Installing Yoeman in a CentOS 7,with the root user, and with the command 'npm install -g yo' I got the following error:

[root@localhost ~]# npm install -g yo

Really the execution has been correct but it has two problems:

  1. /usr/local/bin/yo and /usr/local/bin/yo-complete has no link to the path /usr/bin referenced in PATH environment variable
  2. If we execute /usr/local/bin/ I verify that permissions to the /root/.config/configstore folder are missing and the /root/.config/insight-nodejs folder does not exist

I solved this error with the following actions::

· Create the insight-nodejs folder inside /root/.config (if it doesn't exist, it was my case)

· Assign required permissions: 

chmod g + rwx -R /root/.config/configstore /root/.config/insight-nodejs

· Create the links:

ln -s /usr/local/bin/yo /usr/bin/yo
ln -s /usr/local/bin/yo-complete /usr/bin/yo-complete

Once this is done install Yeoman (me) again with 'npm install -g yo' and certify that Yeoman doctor does not report any errors.


And it is verified that the 'yo --version' command does not return any errors.
