5.6.0xb3 node_modules missing

First time trying to run Unity Editor in Linux, and on the first launch it hangs on the "gettingStarted" / "recent" window and pegs my CPU to 100%. I'm using Ubuntu 16.04, with NPM 3.5.8, Node 4.2.6, Java 8 all set on the PATH. I installed Unity through the Ubuntu Software Center.

My Editor.log is outputting that it can't find a node module:

Code (CSharp):

2. Initialize mono

There is no node_modules directory in /opt/Unity/Editor/Data/Tools/nodejs/bin. Do I need to do something to have Unity install its NPM dependencies? Or is there something else wrong here?

I've checked that my user has ownership of all the unity3d directories in ~/.cache ~/.config and ~/.local. And I've made sure ~/.local/share/unity3d/Packages exists. User root is the owner of /opt/Unity

Any suggestions?

 

After some mucking around I finally got this to work, but it's not a very elegant solution. I'm on Ubuntu 16.04 and here are the steps :

• Copy the node_modules directory from "/usr/share/npm" and paste into "/opt/Unity/Editor/Data/Tools/nodejs/bin/"
• Copy the bin and lib folders from "/usr/share/npm" and paste into "/opt/Unity/Editor/Data/Tools/nodejs/bin/node_modules/npm"

Again, I am using the nodejs and npm packages as installed by apt, so your directories may differ from mine. Hope this helps.

 

I have solved it by adding npm-cli.js path in /opt/Unity/Editor/Data/Tools/nodejs/bin/npm file

 

Thanks for the help guys. I noticed my missing npm-cli.js file was actually at /opt/Unity/Editor/Data/Tools/nodejs/lib/node_modules/npm/bin/npm-cli.js, so I updated /opt/Unity/Editor/Data/Tools/nodejs/bin/npm to point there, which solved my problem.

 

Best, used your fix, and it worked for me, Special Thanks)

 

This fixed black screen on startup problem on Antergos, except the path was different.

 

A lot of thanx Adnaan it was helpful also for Fedora.

 

on Ubuntu 16 install the "nodejs-legacy"
