Your ABP Framework version: 5.2.2 (Stable)
Your User Interface: MVC
Your database provider(EF Core/MongoDB): EF Core

The start template throw AbpException: Could not find the bundle file '/libs/abp/core/abp.css' for the bundle 'Basic.Global'! error .

when I try to run the abp install-libs, it warns the NPM is not installed ,but I have installed it .

I saw there maybe some defects for the yarn detection . #12970 ,is there any way to workaround ,Thanks .

Can you check Setup Environment Steps?

It seems you missed node & yarn steps.

You should run abp install-libs after successfull installation in your project folder to restore client-packages before running your project.

It was solved by running the below commands .

Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope Process
npm install -g npm-windows-upgrade
npm-windows-upgrade
