I'm attempting to create my first Yeoman webapp using the webapp generator. However I get the following errors:

I just installed your generator by running:

    npm install -g generator-webapp

I am pretty sure that node js and yeoman were installed ok. Is there a permissions issue or path issue?

  • Did you try to run this command again as root/Administrator? – Tobino Dec 29 '13 at 15:31
  • @Tobino Thanks for the help. I used some of the information that was supplied in this post to help with this issue.http://stackoverflow.com/questions/18212175/npm-yo-keeps-asking-for-sudo-permission As you correctly identified, the command needed running as an Administrator – Jonathan Beech Dec 30 '13 at 19:17

I thought I was crazy but a lot of people were having the same problem as me.

This may or may not be the right answer for you but, for me it was do a fresh install of node/npm. I really didn't want to because it sounded like opening a can of worms but it's not as bad as it sounds. Within 15 minutes all my Yeoman generators are working and my permissions are good.

@Dominic Tancredi lays it out nicely, and then just see through using NVM to install fresh node. https://stackoverflow.com/a/11178106/1118070

We have the same error, I fixed this by changing the user owner by

chown my_username:my_username ~/.config/configstore/update-notifier-yo.yml

then after that, another error occurred,

npm ERR! stack Error: EACCES, open /home/my_username/.npm/chalk/0.4.0/package/package.json

then change again the owner of ~/.npm directory.

then solved the problem. Hope it will helpful.
