How to fix the missing write access error in npm

Learn, how to fix the missing write access to /.npm-global/lib/node_modules error in npm.

If you install an npm package globally using the npm install -g <package-name> command, you will see an following error inside the terminal.

npm WARN checkPermissions Missing write access to /Users/saigowtham/.npm-global/lib/node_modules
npm ERR! code EACCES
npm ERR! syscall access
npm ERR! path /Users/saigowtham/.npm-global/lib/node_modules
npm ERR! errno -13
npm ERR!
npm ERR! Your cache folder contains root-owned files, due to a bug in
npm ERR! previous versions of npm which has since been addressed.
npm ERR!

To solve this error permanently, we need to run the following command.

sudo chown -R $USER /usr/local/lib/node_modules

• sudo means run this command as a superuser.

• chown means change the ownership of a file or folders

• -R option is used to recursively get the owner access to all files.

• $USER gets the username.

The final thing is folder path /usr/local/lib/node_modules.
