Maybe its too easy but I struggled with this for the last couple of hours and thought my answer here would help anyone who has a similar problem.Īs you can notice from the above, I forgot the letter 'l' at the end of the line leading to npm config setting my 'prefix' to /usr/loca īecause there is no directory by name 'loca'.įew suggestions about disabling SIP to make it work are there but I think it's not a good idea.

It's been 3 years to this Question and there isn't a clear solution to this over the internet. usr/local/lib/node_modules/npm/lib/utils/error-handler.js:205 TypeError: Cannot read property 'get' of undefinedĪt errorHandler (/usr/local/lib/node_modules/npm/lib/utils/error-handler.js:205:18)Īt /usr/local/lib/node_modules/npm/bin/npm-cli.js:83:20Īt cb (/usr/local/lib/node_modules/npm/lib/npm.js:214:22)Īt /usr/local/lib/node_modules/npm/lib/npm.js:252:24Īt /usr/local/lib/node_modules/npm/lib/config/core.js:81:7Īt /usr/local/lib/node_modules/npm/lib/config/core.js:80:13Īt f (/usr/local/lib/node_modules/npm/node_modules/once/once.js:25:25)Īt afterExtras (/usr/local/lib/node_modules/npm/lib/config/core.js:178:20)Īt /usr/local/lib/node_modules/npm/node_modules/mkdirp/index.js:47:53

Please help as this is interfering with my projects.Įrror: EPERM: operation not permitted, mkdir '/usr/loca' I am installing packages for NODEJS/NPM and am receiving the following error, which, apparently, is not an error with the software, but with my MAC.

Npm config set cache
