Running MacOS Sierra (10.12.2), I have a program that can be executed successfully from terminal:
~$ /Users/pf/apps/cfm/bin/cfm-id
Usage: cfm-id.exe <spectrum_file> <id> <candidate_file> <num_highest> <ppm_mass_tol> <abs_mass_tol> <prob_thresh_for_prune> <param_filename> <config_filename> <score_type> <apply_postprocessing> <output_filename> <output_msp_or_mgf>
However, I need to run this program within R, using the system() command. Doing so, I get the following error:
> system("/Users/pf/apps/cfm/bin/cfm-id")
dyld: Library not loaded: libFileParsers.1.dylib
Referenced from: /Users/pf31/apps/cfm/bin/cfm-id
Reason: image not found
>
So the program apparently can't find some of the necessary libraries when it is invoked as a system command from within R.
I've set my environment variables (e.g. DYLIB_LIBRARY_PATH, etc.) in an Renviron.site file and verified these using Sys.getenv().
One hint: if I turn off the "rootless" SIP using csrutil disable, this program (and another that exhibits the same behavior) works fine both in Terminal and using system("/Users/pf/apps/cfm/bin/cfm-id") within R. Unfortunately, if I turn off SIP, this breaks yet another necessary program, such that it will not run properly either in Terminal or within R.
Another hint: if I run the same program from Terminal using sudo, I get the same behavior as with the system() call within R:
$ sudo /Users/pf/apps/cfm/bin/cfm-id
dyld: Library not loaded: libFileParsers.1.dylib
Referenced from: /Users/pf31/apps/cfm/bin/cfm-id
Reason: image not found
Abort trap: 6
Seems odd that the program would fail running as superuser. I'm guessing there is an issue with permissions somewhere, but I don't know how to run it down.

shell_exec("Rscript C:\R\R-3.2.2\bin\code.R ");
This is the call to script.On calling the above script, the error occurs.
I am trying to call my R script from the above path but no output is being shown. While checking the error logs of PHP, it says 'Rscript' is not recognized as an internal or external command, operable program or batch file.' The script is working fine on the Rstudio but not running on the command line.
Add the Rscript path to your environment variables in Windows:
Go to Control Panel\System and Security\System and click Advanced System Settings, then environment variables, click on path in the lower box, edit, add "C:\R\R-3.2.2\bin"
Restart everything. Should be good to go. Then you should be able to do
exec('Rscript PATH/TO/my_code.R')
instead of typing the full path to Rscript. Won't need the path to your my_code.R script if your php file is in the same directory.
You need to set the proper path where your RScript.exe program is located.
exec ("\"C:\\R\\R-3.2.2\\bin\\Rscript.exe\"
C:\\My_work\\R_scripts\\my_code.R my_args";
#my_args only needed if you script take `args`as input to run
other way is you declare header in your r script (my_code.r)
#!/usr/bin/Rscript
and call it from command line
./my_code.r
If you are running it in Git Bash terminal, you could follow a revised version of the idea suggested by #user5249203: in the first line of your file my_code.R, type the following
#!/c/R/R-3.2.2/bin/Rscript.exe
I assumed that your path to Rscript.exe is the one listed above C:\R\R-3.2.2\bin. For anyone having a different path to Rscript.exe in Windows, just modify the path-to-Rscript accordingly. After this modification of your R code, you could run it in the Git Bash terminal using path-to-the-code/mycode.R. I have tested it on my pc.
I faced the same problem while using r the first time in VS Code, just after installing the language package (CRAN).
I restart the application and everything worked perfectly. I think restarting would work for you as well.
I've recently done a (Windows) system update and now I cannot run system commands anymore using R. I've tried to reinstall R and all the used packages but this doesn't resolve my problem. Rebooting also didn't solve the problem.
I just discovered that while the system() and system2() commands don't work anymore, the shell() command does work.
> system('ECHO "test"')
Warning message:
running command 'ECHO "test"' had status 127
> system2('ECHO "test"')
Warning message:
running command 'ECHO \"test\"' had status 127
> shell('ECHO "test"')
"test"
The documentation describes that shell() should be a simple user-friendly wrapper around system(). Therefore I don't understand why shell() works, but system doesn't.
With another computer on which the system() functions still work, I've checked for differences. The Windows version, the R version and the package versions are equal (at least according to sessionInfo() in a clean session). Shell() specifies a few additional arguments compared to system() with which I could play:
shell specifies the shell to be used. The 'Details' section tells me that this will check two environment variables: R_SHELL and COMSPEC. R_SHELL is not defined on both systems (global and local). COMSPEC is defined and refers on both systems to cmd.exe (in the same folder). I've checked and running the pure command via this executable works.
flag no idea what this does, but it is a difference with the system() command. As far as I understand it, the only reason to change it would be when a different shell/OS is used (e.g. Bash on Linux).
intern set to FALSE for both shell() and system().
wait set to TRUE for both shell() and system().
translate set to TRUE, but the system call doesn't contain '/' nor '\'. As expected, playing with this Boolean doesn't change the results.
mustWork related to the output in case of an error. Will return an error or a warning. Changing this Boolean doesn't change the behavior.
Therefore, I can only conclude that shell() does something on top of system() that somehow changes its behavior. This behavior is not specified in the documentation, nor accessible via any of the arguments.
Where could I look for additional differences between both in order to find the source of this bug?
First I tried if I can reproduce this (on Win10):
system('ECHO "test"')
#Warning message:
#running command 'ECHO "test"' had status 127
shell('ECHO "test"')
#"test"
Then I looked at shell's source code and discovered that it changes the command before passing it to system. On my system:
system('C:\\WINDOWS\\system32\\cmd.exe /c ECHO "test"')
#"test"
See also Sys.getenv("COMSPEC") which gives the shell if Sys.getenv("R_SHELL") is empty. Note that the documentation states that the POSIX standards require running commands under a shell. help("system") explains that on a Unix-alike OS system launches a shell and recommends shell (on Windows).
When I run a Julia Script that prints "Hello World" on HTCondor, I get the following error
fatal: error thrown and no exception handler available.
Base.InitError(mod=:Pkg, error=Base.KeyError(key="HOME"))
The code runs without a problem on my local Ubuntu machine. I can run
eval julia --version
in a bash script on condor and the output is
julia version 0.5.0
This problem has been discussed in two places on github: one, two.
ENV["HOME"] is used in a single file and the common recommendation is to modify that. However, I cannot change the julia installation on condor.
Is there a way to fix this on the fly before running a script without sudo?
As #sujeet suggested, it is possible to set environmental parameters in condor. The issue is resolved by adding the following line in the condor submit script
Environment = "HOME=""/tmp"""
, which sets the home directory to the tmp. Julia code runs fine then (as long one is careful not to write to home before resetting it in the script itself).
So I am trying to install a program on my windows machine that required me to install Cygwin to install it. So I am working from a README file and assueme I have compiled the code previously correctly (its one line sh build.sh) and when actually trying to use the program I get the following error:
BabakP#Babak /cygdrive/c/Users/BabakP/Desktop/test
$ ./Runlock input.tst output.tst 1
./Ostrich: Exec format error. Binary file not executable.
I guess I am trying to figure out why I am getting this error so any suggestions on how to troubleshoot it would be great!
./Ostrich is a Mac executable. It can't be executed under Cygwin. (A MacOS emulator that runs under Windows or Cygwin is theoretically possible, but I don't know of any such thing.)
Without knowing the details of the software you're trying to install, it's hard to say how or whether you can fix it.
You may be able to rebuild Ostrich from source (if you have the source, and if it's not MacOS-specfic).
I try to run my R script in Java, thus I installed JRI. and run the example, I am using Eclipse on 64 bits windows 7. part of the example code is as follows:
public static void main(String[] args) {
System.out.println("Creating Rengine (with arguments)");
Rengine re=new Rengine(args, false, null);
System.out.println("Rengine created, waiting for R");
if (!re.waitForR()) {
System.out.println("Cannot load R");
return;
}
However, everytime I run it. it teminated after print out "Creating Rengine (with arguments)" never successfully print out "Rengine created, waiting for R"
I do not know what is right argument to input, I have tried to add "--no-save" under the Program arguments of eclipse run configuration, but still does not help.
any suggestions? Many thanks
Ref: http://www.rforge.net/JRI/
R_HOME must be set correctly
(Windows): The directory containing
R.dll must be in your PATH
(Mac): Well, it's a Mac, so it just
works ;).
(unix): R must be compiled using
--enable-R-shlib and the directory containing libR.so must be in
LD_LIBRARY_PATH. Also libjvm.so and
other dependent Java libraries must
be on LD_LIBRARY_PATH.
JRI library must be in the current
directory or any directory listed in
java.library.path.
Alternatively you can specify its
path with -Djava.library.path=
when starting the JVM. When you use
the latter, make sure you check
java.library.path property first such
that you won't break your Java.
Depending on your system, the R
verison and other features you want
to use, you may have to set
additional settings such as
R_SHARE_DIR, R_INCLUDE_DIR and
R_DOC_DIR.

Running JRI example Java with Eclipse on Mac OS X
Copied the rJava/jri/examples/rtest.java to Eclipse JRI/src/.
Copied the JRI.jar from the jri directory to the JRI/lib/ and added it to the build path.
The rtest.java compiles but it did not run as a Java application.
Apparently, it needs to be run by: ./run rtest.
After examining the "run" shell script which comes with the rJava package (inside ./jri/), I have set up these in the Eclipse run configuration:
Environnment:
R_HOME = /Library/Frameworks/R.framework/Resources
PATH=/Library/Frameworks/R.framework/Resources/bin/
In addition, the example run shell script sets up the following Environment vars:
R_INCLUDE_DIR=Library/Frameworks/R.framework/Resources/include
R_SHARE_DIR=Library/Frameworks/R.framework/Resources/share
R_DOC_DIR=Library/Frameworks/R.framework/Resources/doce
JRI_LID_PATH=Library/Frameworks/R.framework/Resources/lib:/Library/Frameworks/R.framework/Resources/bin
VM argument:
-Djava.library.path=/Library/Frameworks/R.framework/Resources/library/rJava/jri/
JRI.jar is now referenced in the build path, which is:
/Library/Frameworks/R.framework/Resources/library/rJava/jri/JRI.jar.
This automatically appears under the -cp tab in the run configuration.
Also, the run configuration requires a program argument: --save, --no-save or --vanilla.
Chances are it's not finding jri.dll or R.dll. If you see nothing, not even an exception, the JVM is crashing. Look for files like hs_pid* which should tell you which library is the culprit.
I have found this question in my own struggles with R on Windows, although on Linux it just worked.
I too found I was getting "Creating Rengine (with arguments)" but nothing further.
It was finding jri.dll and R.dll, which I was able to prove:
jri.dll - deleted it from the current directory, which generated the error:
Cannot find JRI native library!
Please make sure that the JRI native library is in a directory listed in java.library.path.
java.lang.UnsatisfiedLinkError: no jri in java.library.path
(on copying it back, make sure to take the right 32 or 64 bit version to avoid "Can't load IA 32-bit .dll on a AMD 64-bit platform" type errors)
R.dll lives under the installation directory C:\Program Files\R\R-2.15.0\bin\x64
If the PATH is set incorrectly in the run.bat file (which it was) then you get the slightly different error
Cannot find JRI native library!
Please make sure that the JRI native library is in a directory listed in java.library.path.
java.lang.UnsatisfiedLinkError: [CURRENT DIR]\jri.dll: Can't find dependent libraries
With those two things set correctly (and no hs_pid* files being generated) I found the problem to be the lack of R_HOME in run.bat. Adding
set R_HOME=C:\Program Files\R\R-2.15.0\
fixed it, and now it all seems to work for me. I did not need to add --save, --no-save or --vanilla to the script. Also, it had 'runtest' hardcoded, so ./run.bat runtest2 will not DWYM.
Short answer: The Windows run.bat script was broken (whereas the Linux 'run' script was correct out of the box).
I got the same problem while working with rJava, Windows 7 64 bit.
And here is the solution.
Added -Djava.library.path="${env_var:PATH}" in eclipse -> Project -> Run As -> Run Configuration -> Arguments.
And make sure System.getProperty("java.library.path") is pointing to jri.dll
I spent lot of time on this issue, so feel free to ask any questions ;)
The below error can be due to two paths not set, one is r.dll not found or/and jri.dll not found. Make sure system path includes for 32 bit systems
%R_HOME%\bin;%R_HOME%\bin\i386;%R_HOME%\library\rJava\jri\i386
Also make sure install.packages("rJava") plugin is installed from R console
Cannot find JRI native library!
Please make sure that the JRI native library is in a directory listed in java.library.path.
