Typically when installing a new npm packages globally in your system, you will run into an error something like Error: EACCESS permission denied something.
Don't worry, information technology'southward natural I'g here to assist you lot to fix this kind of mistake.
Normally I'm using node version manager (nvm) to handle my node versions, so I can easily switch to whatsoever version I adopt only we volition not talk over information technology here. I'll create a separate web log post for that on how to set a multiple node version using NVM (node version manager).
So allow's take a look the error that most probably something like this below:
Fault:
npm ERR ! Fault: EACCES, open '/Users/letscodepare/.npm/-/all/.cache.json' npm ERR ! { [ Error: EACCES, open up '/Users/letscodepare/.npm/-/all/.cache.json' ] npm ERR ! errno: 3 , npm ERR ! code: 'EACCES' , npm ERR ! path: '/Users/letscodepare/.npm/-/all/.enshroud.json' } npm ERR ! Please try running this command again as root/Administrator. .. .. . .. .. . Solution:
- Open up upwardly your favorite terminal and run this code
sudo chown -R $(whoami) ~/.npm Then what does it do? 
chown is a unix control which means "modify owner". From that definition based on our code above we are going to change the possessor of our binder ~/.npm which for sure the "root" user is applied.
We're going to assign this folder recursively to our own username using this command whoami so that it will exist piece of cake to read and write anything nosotros desire.
Notation: Somehow, even when we change the possessor of ~/.npm folder, we still encounter an EACCES error. To Fix that, nosotros should change the possessor of our node_modules binder.
sudo chown -R $(whoami) /usr/local/lib/node_modules/ Voila
Now you tin finally install npm packages without sudo.
