Can't install expo-cli -g

I'm new in react-native, I'm trying to set up my project after all package install when I tried to start npm start command then show me 'expo-cli' is not recognized as an internal or external command, this error.
ok, then I have followed the guide from here
after that I have added my env path in this way:
environment variable > System Variables > PATH >
C:\Users\YOUR_USERNAME\AppData\Roaming\npm
then I have to install again:
npm install -g expo-cli
but it does not work for me, I don't know why.
when I try to run this command npm install -g expo-cli then show me an error like this:
PS C:\Users\alami\OneDrive\Desktop\React native\starter-react-native> npm install -g expo-cli
npm ERR! code EPERM
npm ERR! syscall mkdir

At least I just solved my problem in this way:
Search cmd
Then run as administrator
Then npm i -g expo-cli
I just solved my problem.

permissions issue when trying to update npm

I tried to update to the latest version of npm and got this error? Anyone ever have a permission error with npm before? I'm stuck as to how to fix it.
