Node.js — npm ERR! Error: EACCES: permission denied, mkdir ‘/home/artheman/.npm

Problem:

I cannot install a semantic-ui using npm. When I encounter an error like this usually the solution is using a sudo command. Please don’t ever use npm with sudo (eg: sudo npm install semantic-ui) because it will make a headache for you.

[sourcecode language=”bash”]
artheman@ub3c:/var/www/_php/ci-blog(master)$ npm install semantic-ui

Solution:
We just reclaim the ownership like this..
sudo chown -R $(whoami) ~/.npm

And thats it..
