“ npm i -g gulp”安装错误

Question

I'm trying to install this: npm i -g gulp

But the output are these lines:

npm ERR! Darwin 16.3.0
npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "install" "-g" "gulp"
npm ERR! node v7.4.0
npm ERR! npm  v4.0.5

npm ERR! code EACCES

npm ERR!   syscall: 'access',
npm ERR!   path: '/usr/local/lib/node_modules' }
npm ERR! 
npm ERR! Please try running this command again as root/Administrator.

Just in case: when I ran npm root -g , I got the correct root folder: /usr/local/lib/node_modules

Please, how can I solve this? And install npm i -g gulp ??

Thanks!

Answer 1

see the error message: EACCES: permission denied . Link to fixing npm permissions .

for me, on a new system I'll execute the command found at the reference above:

 sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}

There is another option show at the link above for changing the directory where NPM installs packages to.
