react The operation was rejected by your operating system. npm ERR! It is likely you do not have the permissions to access this file as the current user code example

Example: npm ERR! path /usr/local/lib/nodejs/node-v10.15.3-linux-x64/lib/node_modules while installing angular cli

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
