Cli Migration from CLI 2 to CLI 3

[reqee99]

I have latest stable version of Node.js , Lastest Version of Git and also Ruby as well, But when I run CMD of npm install -g @Shopify/cli@latest i got the CLI 2 , I even uninstall everything and reinstall everything but still I got CLI 2 ! Is there any solution please 🙏

try gem uninstall shopify-cli and If not delete by this command then 
You have to find all the file on which drive you have installed earlier and need to delete everything manually.

If still not found anything then please go-through the https://github.com/Shopify/cli/issues/1405 .

that also not work then uninstall all dependencies(ruby, bundler, git and Shopify cli 2 files from system manually).
after that try to install cli 3
