Dear community,

I can not install lest version of Truffle Suite in VS Code and Ganache also.
I got this after I typed: npm install -g truffle@latest

npm ERR! code EACCES
npm ERR! syscall mkdir
npm ERR! path /usr/local/lib/node_modules/truffle
npm ERR! errno -13
npm ERR! Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/truffle'

npm ERR! code: 'EACCES',
npm ERR! syscall: 'mkdir',
npm ERR! path: '/usr/local/lib/node_modules/truffle'
npm ERR! }
npm ERR!

Hi,
have you read the advice here:
https://trufflesuite.com/docs/vscode-ext/installation-guide/

You are using macOS, have you installed node with a version manager such as "nvm"? That is the cleanest way to avoid any permission (EACCES) errors while installing npm packages.

Warm regards,
Chris | Truffle | ConsenSys

Your npm setup has permissions issues (maybe you used sudo?).

npm doctor is a useful diagnostic tool that returns the status of your npm setup, and hints to fix if necessary.
