Install expo-cli global

npm i expo-cli --global.txt

I used these to install it:

bash you need to change the default terminal as bash first.
-> https://conemu.github.io/

maybe the new windows terminal does support bash too
-> https://github.com/microsoft/terminal/releases

Install Nodejs: (I don't need a higher version and it can give errors.)
-> v12.9.0

clean npm cache
-> npm cache verify

then run I ran this command on conEmu
-> npm install expo-cli --global --no-optional
or
-> npm i [email protected] --global 
or
-> npm install expo-cli --global 

Voilà!

I hope this works for you too.

Plus, if you need to upgrade your older expo project to a newer version then you may check these steps too.
