I have been trying to set up development machine for Rocket.Chat on Ubuntu 16.04. Followed the steps given for prerequisite installations on the site and trying to execute npm start meteor. However the process fails at command meteor npm i && meteor.
Below is the log of error that is
Any pointers on what is the possible issue. Pretty new to the framework and did not get any specific answer for my error on the forum.

I am using react native and Expo. I am unable to build new app because after I use expo init appName it shows the following error.
Heres the full message:
📦 Using npm to install packages. You can pass --yarn to use Yarn instead.
√ Downloaded and extracted project files.
× Something when wrong installing JavaScript dependencies. Check your npm logs. Continuing to initialize the app.
✅ Your project is ready!
To run your project, navigate to the directory and run one of the following npm commands.
- cd Scanner
- npm start # you can open iOS, Android, or web from here, or run them directly with the commands below.
- npm run android
- npm run ios # requires an iOS device or macOS for access to an iOS simulator
- npm run web
I tried multiple times to create a blank project, also tried npm install to install failed/not downloaded libraries and continue after failure but it showed another error:
npm ERR! code Z_BUF_ERROR
npm ERR! errno -5
npm ERR! zlib: unexpected end of file
also tried npm cache verify that showed cache is ok Content verified: 3562 (252580364 bytes).
So, How can I solve this issue?
Problems related to npm installation are very common If you do any mistake in early installation, but is avoided. Learn more about npm tree.
Steps worked for me are :
npm cache clean --force
npm cache verify
npm -g uninstall expo-cli --save
npm install expo-cli --global
expo init app-name
cd app-name
npm start
Always run as administrator if working on Windows and in root directory.
The solutions above didn't work for me but if you use 'npm install' in the directory of the app you get a clue that you shuold try 'npm install --force'
err message
You should have all these files folders and files at the start of the project otherwise not all the dependencies have been installed which is why we were getting the problem.folder structure
After you have added --force to npm install you have all the dependencies installed. Now you can run the app with npm start.
Unfortunately, all the solutions described above didn't work on my machine...
Here is my latest solution for this problem...
This worked 100% on my machine...
Use npm i -g expo-cli
This will automatically add the required packages and also remove the unnecessary ones.
Yes, surely, you don't need to uninstall and re-install it again.
Just follow my steps.
And, you can create your expo project using expo init.
I hope my solution will help you out from this annoying problem....
I just did npm install and it worked for me, but I had do that every time I create a new expo project.
I also encountered this problem, and finally found that it was the problem of react native cli，I installed the latest version of react native cli，Expo is back to normal
This Error is regarding to the git account. expos need a git account to setup react native project
If you are using windows you need to install git in your local PC
after that open your Terminal and type this command
git config --global user.name "your_username"
git config --global user.email "your_email_address#example.com"
after that clone any github project to your local computer. it will ask to login to Github
after all these steps try expo init <projectname>
The simple way to settle that error is by using "expo-cli init app-name" instead of "expo init app-name".
I tried and worked perfectly for me. Hope it will help you guys.
i have faced a similar problem and running yarn set version 1.22.1 fix it
Run the Command Prompt as an administrator. And run the following command:
npx create-expo-app AwesomeProject
I am trying to deploy an app that has been upgraded to meteor 1.7 using the setup for passenger outlined at puhsionpasserger.com, however when I try and access the app I get an error in the console of
Error: The core-js npm package could not be found in your node_modules directory. Please run the following command to install it: meteor npm install --save core-js
Being shown on the web page (although the favercon is correct so its trying).
The app runs fine locally (as in on the dev machine).
Give its deployed, meteor doesn't exist on the machine.
I tried npm install --save core.js and it reported one package installed, but still no joy on the app front.
I'm not sure where to go from here. Any thoughts?
Edit:
I just tried building the app without the --server-only flag with no change. Deployed the app the way I do with the v1.3 instances of the app and no change.
One thing that I did get when running npm intall from the /programs/server directory was
Binary is fine; exiting
npm WARN lifecycle meteor-dev-bundle#~install: cannot run in wd %s %s (wd=%s) meteor-dev-bundle# node npm-rebuild.js /opt/bundle/programs/server
added 131 packages in 13.857s
I'm not sure if the warning means anything in particular.
I know how to package and then deploy meteor application. But recently for one project i'm stuck at an error which i couldn't resolve.
Steps I followed for package and deploy of my meteor app:
1. meteor build package
2. cd package
3. tar -xf inventoryTool.tar.gz
4. cd bundle/programs/server
5. npm install
6. cd ../..
7. PORT=<port> MONGO_URL=mongodb://127.0.0.1:27017/dbName ROOT_URL=http://<ip> node main.js
Here is the log for the error when i run the npm install(STEP 5) command.
Is there anything missing in my execution?. I'm not using the fibers package anywhere in my project. Does anyone have solution to this problem? Thanks in advance.
Why this happens (a lot)?
Your local version of node is v8.9.4. When using the build command, you will export your application and build the code against this exact node version. Your server environment will require this exact version, too.
An excerpt from the custom deployment section of the guide:
Depending on the version of Meteor you are using, you should install
the proper version of node using the appropriate installation process
for your platform. To find out which version of node you should use,
run meteor node -v in the development environment, or check the
.node_version.txt file within the bundle generated by meteor build.
Even if you don't use fibers explicitly it will be required to run your Meteor app on the server correctly.
So what to do?
In order to solve this, you need to
a) ensure that your local version of node exactly matches the version on the server
b) ensure that you build against the server's architecture (see build command)
To install a) the very specific node version on your server you have two options:
Option I. Use n, as described here. However this works only if your server environment uses node and not nodejs (which depends on how you installed nodejs on the server).
II. To install a specific nodejs version from the repositories, you may do the following:
$ cd /tmp
$ wget https://deb.nodesource.com/node_8.x/pool/main/n/nodejs/nodejs_8.9.4-1nodesource1_amd64.deb
$ apt install nodejs_8.9.4-1nodesource1_amd64.deb
If you are not sure, which of both are installed on your server, check node -v and nodejs -v. One of both will return a version. If your npm install still fails, check the error output and if it involves either node or nodejs and install the desired distribution using the options above.
To build b) against the architecture on your server, you should use the --architecture flag in your build command.
I’m trying to get sqlite3 to work in an electron app running on Windows7 and 10. Running the following command, I was able to create electron-v1.7-win32-x64\node_sqlite3.node
cd node_modules/sqlite3 && sudo npm install nan
&& sudo npm run prepublish && sudo node-gyp configure --module_name=node_sqlite3 --module_path=…/lib/binding/electron-v1.7-win32-x64
&& node-gyp rebuild --target=1.6.11 --arch=x64 --target_platform=win32 --dist-url=https://atom.io/download/atom-shell
--module_name=node_sqlite3 --module_path=…/lib/binding/electron-v1.7-win32-x64
However, I get Uncaught Error: %1 is not a valid Win32 application. \\?\c:\folder\ppt_win32-x64\resources\app\node_modules\sqlite3\lib\binding\electron-v1.7-win32-x64\node_sqlite3.node.
My node version is v7.4.0. Electron v1.6.11.
I was trying to compile for windows from mi Mac and I had that problem too, but after some readings I figured out how to proceed, and after all I can say that I got it. Yesterday I spent all day setting up a windows virtual machine in my (other) Linux laptop (I used my linux laptop just because my mac was exhausted in storage...). I was having too a problem with the preloadScript from electron main process in windows, Cant found the script, it was solved too.
Anyway, I think the library node printer from #tojocky is well maintained, in other hand in the electron-builder documentation they say that you should compile in native for natural reasons. Once you will have it, you'll see that it's a cleaner and pragmatic solution ...
This was my entire process, I hope it helps to someone having the same issue:
Get VirtualBox (or Parallels but is not free)
Get iso for W10
Create a VM with this W10 iso, and you should give to this VM some storage (because some dependency that you'll need to compile), I have assigned 60gb to this VM
Once I had that VM running, I just installed in that machine Visual Studio 2017 (with their build-tools included, it's necessary)
And then, I used CMD to make the rest
Install NodeJS (and NPM, but it comes with)
Install node-gyp globally
Install Python 2.7
Clone your project from git (in my case)
npm i (in your project), you should have as npm dependency in your package.json the module electron-builder of course. (here I had some troubles because when node-gyp tried to rebuild printer to generate the binary for windows it was failing, this was because it was imposible to find the python executable, so if you face this problem you should add it like:npm config set python "c:\Python27\python.exe" in my case )
Then try again npm i and Voila!
If you still having error you can rebuild the native dependency as well, run:
node-gyp rebuild --target=YOUR_ELECTRON_TARGET[eg: 1.8.4] --arch=YOUR_ARCH_TARGET[eg: x64 | ia32] --dist-url=https://atom.io/download/atom-shell
After all, you should make the build using electron-builder, in my case my npm script command was build --win --x64 but you can use the --ia32 flag as well for 32bits
I just started learning Meteor JS on a fresh copy of OSX. I used the Meteor install instructions to install it. Everything works well - I can install Meteor packages and run the local instance. But where is Node.js and npm? I assume it must be installed with Meteor because everything runs, but the npm and node command is not available. Am I supposed to install Node separately?
Thanks,
Kevin N.
Edit: Corrected npm in the question title which OS X keeps changing to nom.
As of METEOR#1.1.0.2, node and npm are stored in :
/home/username/.meteor/packages/meteor-tool/1.1.3/mt-os.linux.x86_64/dev_bundle/bin/
(The path depends on both the username and architecture of course).
If you're doing only Meteor dev, you won't need node on its own, you might however need npm to install Meteor related tools such as Meteor Up (mup), in which case you need to install npm separately or alias the command to use the Meteor one.
