npm install ganache -g failed | Ubuntu 21.10 | node -v v18.0.0 npm -v 8.8.0

Hello @trufflesuite

i am trying to install ganache on ubuntu with the following

npm install ganache --global

i got this errors:

user@ubuntu~$ npm install ganache --global
npm ERR! code EACCES
npm ERR! syscall mkdir
npm ERR! path /usr/local/lib/node_modules/ganache
npm ERR! errno -13
npm ERR! Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/ganache'

i search online that on linux you have to use:

$ sudo npm install ganache --global

but for obv reasons, installing npm package with sudo privileges, is not a best practice but this means that i change node_module folder parameters/variables and it could be dangerous for security reason. Am I correct?

Ganache GUI and ganache, the command line package, are different things (GUI uses its own ganache cli instance internally based on ganache v6)

Was my last answer to this question not sufficient?

Note: official Node 18 support will be in the next release. Try Node 16.
