I installed a pre-compiled version of R-3.3.3 on my computer and also used ./configure and make to install a R-3.2.3. I found out that my RStudio is using 3.3.3, and now I want to delete 3.2.3. How can I do it?
Now a bit of background of my current setup:
I have Python3.3 running on Centos 6. I'm currently working on a web application using Flask that runs on Apache 2.2.15 with mode WSGI 4.5.3 and virtualenv 15.0.2.
pip --version pip 8.1.2 from /usr/local/bin/lib/python3.3/site-packages (python 3.3)
I have installed pysvn with pip and when I run pip show pysvn says
Location: /usr/local/bin/lib/python3.3/site-packages
755 permissions recursively set to /usr/local/bin/lib/python3.3/site-packages. And I passed --system-site-packages argument to virtualenv to use the global site packages.
Even when I try to import the package from python interpreter it does not work. So it is not specific to my virtualenv setup but rather a global problem.
I must mention that other packages installed with pip work perfectly fine (i.e. flask).
I've exhausted all other avenues before coming forward to you guys. Any suggestion would be highly appreciated as I ran out of ideas.
L.E.
I did manage to install it in the end. I'm not completly sure yet why and how but I presume is was compatibility issue.
First of all I have uninstalled svn 1.6+ and installed version 1.8.16 instead which seems to be tested against the latest two versions.
Second, I have uninstalled the troublesome pysvn instance and installed pysvn-1.8.0 workbench "sudo /var/www/FlaskApp/FlaskApp/flask/bin/pip install pysvn-1.8.0.tar.gz". In this case I have installed it my local environment. The 1.9.0 version of pysvn did not work.
L.L.E.
False positive, still doesn't work. I'm going to interact with svn via command line from my script.
L.L.L.E.
After installing svn 1.8.16 and svn-devel along with the rest of dependencies described in the readme file I have managed to successfully install it from the source fallowing the instructions.
Thanks for your help Barry.
pysvn is not available from PyPI because PyPI has no way to allow me to upload pysvn for each supported SVN version. Let alone deal with the issues of installing on a Linux distro given the choices for pysvn dependencies.
(APR, SVN, OpenSSL etc).
Fedora packages pysvn for the Fedora release.
I'm assuming that means it is on RHEL and therefore packaged by CentOS.
(But I do not have RHEL or CentOS to check this on)
If you find that a package is not available for your CentOs is not hard
to build pysvn on a linux distro. Get the source kit and follow the readme.html should get you going.

Suddenly today, without us changing any configuration, all test containers began to fail because of the following error:
$ sudo -E apt-get -yq --no-install-suggests --no-install-recommends --force-yes install libqt5webkit5-dev qtdeclarative5-dev
Reading package lists...
Building dependency tree...
Reading state information...
E: Unable to locate package libqt5webkit5-dev
E: Unable to locate package qtdeclarative5-dev
We have the following configuration in our .travis.yml in order to use QT5 on Travis with Ubuntu 12.04:
apt:
sources:
- ubuntu-sdk-team
packages:
- libqt5webkit5-dev
- qtdeclarative5-dev
We've tried to fix this but are baffled. Any ideas? Anyone else experiencing this?
We had the same problem and after contacting Travis support I learned that apparently the ubuntu-sdk-team has stopped providing packages for Precise and you need to switch dist to Trusty. In order to get the builds working again add this to your .travis.yml file
sudo: required
dist: trusty

Ubuntu 12.04 will be deprecated in less than a year from now (exactly at 2017-04-26), and also Qt Webkit is deprecated with the new versions of Qt starting from Qt 5.5. It is removed in Qt 5.6 from the Qt distribution:
With 5.6, Qt WebKit and Qt Quick 1 will no longer be supported and are
dropped from the release. The source code for these modules will still
be available. You can continue to compile and use these modules, but
we will not be supporting them any longer.
http://blog.qt.io/blog/2016/03/16/qt-5-6-released/
So, you in order to maintain the stability of your development environment, either you have to stay with the current versions of Ubuntu and Qt (which has its own issues), or you have to port your code to work with the newer versions of Ubuntu and Qt, like Qt 5.5 on Ubuntu 16.04 LTS.
I am trying to get qt webengine running on my laptop for the first time, but can't seem to build it. I am following the instructions from here:
https://wiki.qt.io/QtWebEngineHowToTry
On the last few steps, I had to run "qmake -r" on the qtwebengine directory. This is the output:
SSL............................... Using system NSS
ICU............................... Using internal copy (Default, force system ICU with WEBENGINE_CONFIG += use_system_icu)
FFMPEG............................ Using internal copy (Default, force system FFMPEG with WEBENGINE_CONFIG += use_system_ffmpeg)
Proprietary codecs (H264, MP3).... Not enabled (Default, enable with WEBENGINE_CONFIG += use_proprietary_codecs)

Project ERROR: Unknown module(s) in QT: webchannel
This error happened right after I installed WebKitGtk+ from here (http://trac.webkit.org/wiki/BuildingGtk) and ran "Tools/gtk/install-dependencies" and "Tools/Scripts/update-webkitgtk-libs". Before I installed WebKitGtk+, qmake would terminate at a later point.
(I installed WebKitGtk+ because, previously, running "qmake -r" on the qtwebengine directly resulted in an "unmet dependency: harfbuzz" error that I tried to fix on my own via google, and the WebKitGtk+ page was the only lead I could find that would supposedly fix that issue... big mistake!).
I am running on a (mostly freshly reformatted) Ubuntu 15.04 laptop. I installed qt5 via apt-get install, but apparently I have both qt4 and qt5 plugins installed, as well as qtchooser (I'm guessing from the WebKitGtk+ installation scripts).
Here is the output of "qmake --version":
QMake version 3.0
Using Qt version 5.4.1 in /usr/lib/x86_64-linux-gnu
Any help would be greatly appreciated, as I'm excited to try out qt webengine!
In case anyone else has the same problem, I fixed it by installing qt 5.5.0 from here http://download.qt.io/official_releases/qt/, and using the associated qmake binary from that installation. I guess installing qt from 'sudo apt-get install' still has some issues that won't work with qtwebengine.
I am trying to install iPDC on a Centos unix laptop.
I am getting a make error when I attempt to install the programme - I have attached a screenshot of my problem.
The command run is sudo make install and I am attempting to install as the root user.
Your installed GTK version is probably too old to support this software. GtkBuilder (a component within GTK) showed up at version 2.12. To find out what version you have, run pkg-config --modversion gtk+-2.0 at the command line. But that version has been around for quite some time. What version Centos are you running? I assume 5, which is quite old.
Upgrading GTK can be tricky, as most of your desktop software relies on it. If you're in for an adventure, the "easiest" would be to upgrade your Centos OS (to 6.x). You might be able to compile a more recent GTK from source and keep it separate from your system GTK, but that will take some patience.
It seems that GTK is not installed.
Try something like: yum install gtk2 or yum install gtk2-devel
