How can i install vue cli?

Question

I come here to solve this problem: I have installed node (Ver. 12.13.1) in my computer, then I use node -v to see if node are well installed, and yes, it is.

Later, I use npm install @vue/cli, it installs the framework, but when a do a vue --version throws me a error.

I have tried in the terminal of visual studio code and throws me the error too. I tried uninstall and install node, and do the before stuff again, but its not working, the error remains

What could I do? Why is this happening?

Error in english:

Cannot load file C:\Users\halva\AppData\Roaming\npm\vue.ps1. 
The file C:\Users\halva\AppData\Roaming\npm\vue.ps1 is not digitally signed.
You cannot run this script on the current system.

This looks like an issue with PowerShell... Try to run this first (if you would have read the error message, and gone to the link they provide, it gives you all the answers you are looking for) Set-ExecutionPolicy -ExecutionPolicy Bypass — Matt Oestreich

Can confirm this is a powershell issue:

Please read this github issue on the matter: https://github.com/vuejs/vue-cli/issues/3424

People have suggested getting the same issue with vue-cli installed globally.

Solution: delete the erroring file: File C:\Users\halva\AppData\Roaming\npm\vue.ps1.

Sidenote: What I suggest is to not use powershell, and use something like gitbash: https://gitforwindows.org/ (but this is entirely an opinion)

this command help to get rid off error message and execute the command, I am sharing here for help, looks like you should be sure whatever libraries you are using they are safe for your computer.
