It’s not recommended to use sudo with npm install, follow the steps from npmjs official docs instead 🙂
Make a directory for global installations:
mkdir ~/.npm-global
Configure npm to use the new directory path:
npm config set prefix '~/.npm-global'
Open or create a ~/.profile file and add this line:
export PATH=~/.npm-global/bin:$PATH
Back on the command line, update your system variables:
source ~/.profile
Test: Download a package globally without using sudo.
npm install -g typescript
