Getting “node is not recognized as an internal or external command” when using npm install expo

Question

I'm trying to install expo cli using npm install -g expo-cli after uninstalling it but I'm getting the following error:

> @expo/traveling-fastlane-linux@1.15.1 preinstall C:\Users\owl\AppData\Roaming\npm\node_modules\expo-cli\node_modules\@expo\traveling-fastlane-linux
> node platform.js

I used to have no issues installing npm packages, I don't know if I accidentally deleted some files

• the nodejs has already been added to the path in the environment variables
• I've tried re-installing npm and nodejs, clearing npm cache, restarting but nothing seems to be working:(

$ npm --version
6.14.5 

$ node --version
v12.18.2

Any suggestions?
Thank you

Update: Starting the terminal as an admin and running the command again solved the problem:)

For anyone who could be facing a similar problem, try running the command while using the terminal as an admin
