I'm trying to set up yo to use the angular generator for a project. I am following the steps detailled here: http://yeoman.io/learning/index.html
I already have Node.js and NPM installed.
But when I use the command:
sudo npm install -g yo bower grunt-cli
It fails and I get this error:
> [email protected] postinstall /usr/lib/node_modules/yo/node_modules/cross-spawn/node_modules/spawn-sync
> node postinstall
fs.js:439
return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);

I tried to use chmod 777 on /usr/lib/node_modules
but it doesn't seem to work better.
I can install Bower and Grunt, it worked, but when I try to install Yo, it fails everytime...
I have no idea what to do as everything I tried using chmod
or chown
didn't work.
Thanks for your help guys! :)
I worked around the issue by using:
sudo npm install -g yo --unsafe-perm
Use of --unsafe-perm
suggested by nyakto in this bug report.
Edit - realised that this is the URL posted by @Stephan in his answer.
I don't know the specifics about --unsafe-perm - I can only state that it allowed me to install yo without errors I experienced that were very similar / identical to OP.
