Permission denied while installing Yo

问题

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:

> spawn-sync@1.0.11 postinstall /usr/lib/node_modules/yo/node_modules/cross-spawn/node_modules/spawn-sync
> node postinstall


fs.js:439

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! :)

回答1:

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.

The comment in the github repo fixed my issue. Basically just needed to update node version. Listing out the steps for future reference:

sudo npm cache clean -f
sudo npm install -g n
sudo n stable
node -v

Cheers

Have a look at this bug report: https://github.com/ForbesLindesay/spawn-sync/issues/11

回答4:

I had the same issue . Apparently a common isse with yeoman. doing the following solved my issue try deleting all files in the /Users/yourusername/.config/configstore/ directory and then run the yo command as usual.

回答5:

I had same issue too,under linuxmint 17. Cause I use nodejs 0.10,and I upgrade npm to 2.X.

Try to reinstall nodejs and select the correct version https://github.com/nodesource/distributions

Good luck!
