NPM permission error while installing

Question

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         


        

Answer 1

To avoid permission errors, install node with nvm.

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

Answer 2

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.

Answer 3

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

Answer 4

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