i am trying to install yeoman on my server but for some reason do i keep getting a permission denied error.

$npm install -g yo /root/.node/bin/yo -> /root/.node/lib/node_modules/yo/cli.js > [email protected] postinstall /root/.node/lib/node_modules/yo > yodoctor sh: 1: yodoctor: Permission denied npm ERR! [email protected] postinstall: `yodoctor` npm ERR! Exit status 127 npm ERR! npm ERR! Failed at the [email protected] postinstall script. npm ERR! This is most likely a problem with the yo package, npm ERR! not with npm itself. npm ERR! Tell the author that this fails on your system: npm ERR! yodoctor npm ERR! You can get their info via: npm ERR! npm owner ls yo npm ERR! There is likely additional logging output above. npm ERR! System Linux 3.13.0-37-generic npm ERR! command "/usr/bin/node" "/usr/bin/npm" "install" "-g" "yo" npm ERR! cwd /root npm ERR! node -v v0.10.33 npm ERR! npm -v 1.4.28 npm ERR! code ELIFECYCLE npm ERR! not ok code 0

I think Shantaru is right, you need to do it with sudo.

Try this

sudo npm uninstall -g yo sudo npm cache clean sudo npm install -g yo

I have a similar problem weeks ago and that works.

Edit: If that didn't work, do this before:

npm config set unsafe-perm true

try this: npm install -g [email protected]
weird... please try to set: npm config set unsafe-perm true
Glad to read that! But i think that's not a right solution, only a temporal workaround. Something is wrong with your users and permissions... try to delete everything about node and do a fresh install in the recommended ways when you want to do another try. Good luck!
npm config set unsafe-perm true fixed the issue for me as well. I am installing yo as root on a server using npm install -g yo.
Thanks, i add the set unsafe-perm in the answer for future visitors.

You need to have root permission to install this so try "sudo npm install -g yo" instead of "npm install -g yo"

I had the same issue and tried running the install using 'sudo npm install -g yo' but it still failed. I couldn't get away from the fact that the error message still said 'sh: 1: yodoctor: Permission denied', indicating a permissions issue. I therefore tried completely changing to the root user using 'sudo su' and THEN running 'npm install -g yo'. This worked for me.

If, like me, when running the install that way you encounter other errors, it could be because you need to upgrade npm first (run 'npm install -g npm' to do that). It could also be because you have yo partially installed from your previous attempts and that's causing issues. Therefore you can try removing it first using 'npm remove -g yo' (still as root user) and then installing it again using 'npm install -g yo'.

Hope this helps someone out there.

To avoid permission errors, install node with nvm.

See the detailed solution here: npm install g less does not work
