Error installing yeoman

问题:

Installing Yeoman on my OSX machine results in the following error:

paulh16$ npm install -g yo npm http GET https://registry.npmjs.org/yo npm http 304 https://registry.npmjs.org/yo npm ERR!

I believe the problem is that bash is looking for npm within the Ruby Version Manager, which is where I installed node and npm originally. However, I removed both from RVM and installed from the Node website. I also adjusted my .bash_profile:

PS1="\u$ " export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH" export DYLD_LIBRARY_PATH="/usr/local/mysql/lib:$DYLD_LIBRARY_PATH"  if [ -f ~/.git-completion.bash ]; then    source ~/.git-completion.bash fi  [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM$ 

I don't understand why the Yeoman installation is failing.

回答1:

This solved the issue for me. Setting the permission on the npm folder in your home directory was the fix for me.

sudo chown -R `whoami` ~/.npm 

回答2:

The npm command fails because you need to be root to edit files under /usr/.

You should properly configure npm, see this relevant SO answer:

$ echo prefix = ~/.node >> ~/.npmrc 

回答3:

try

sudo chown -R $USER /usr/local

and this kind of problem would be solved forever

it's not encouraged to npm with sudo

回答4:

For me on Ubuntu only the following worked for me...

Ubuntu

Tested on Ubuntu 14.04.2

This was a base install of Ubuntu 14.04.2 on VirtualBox using ubuntu-trusty-64.

I had just installed node and npm fresh and they were working well.

npm install -y -g yo echo export PATH="$HOME/npm/bin:$PATH" >> ~/.bashrc npm config set prefix ~/npm echo "export NODE_PATH=$NODE_PATH:/home/$USER/npm/lib/node_modules" >> ~/.bashrc && source ~/.bashrc npm install -y -g yo 

yes I had to install yeoman, fix the path issues, then reinstall yeoman. based on some answers on this stack overflow post

回答5:

This worked well for me:

sudo npm install -g yo
