Could not install dotnet-aspnet-codegenerator tool

Question

When I right click the controllers folder and select add, new scaffolding, empty MVC Controller, the ASP.NET Core Scaffolder gives me this error. I then added it to the project through the Nuget Manager and still have no luck. I am new to .NET and Visual Studio so any help is appreciated.

I am following this video tutorial to implement CRUD on asp.net MVC https://www.youtube.com/watch?v=C5cnZ-gZy2I

I've had similar issues in the past that were solved with adding something to my $PATH so here is the output of echo $PATH

Answer 1

When Visual Studio attempted to install "dotnet-aspnet-codegenerator" it would bomb because of the space located in the path "Google Drive". I moved the project to a directory with no spaces and it works fine.

It worked for me:

1. dotnet tool uninstall -g dotnet-aspnet-codegenerator
2. dotnet tool install -g dotnet-aspnet-codegenerator

...and if it is still not working:

3. Make sure your Project is in the default folder: /Users/yourname/Projects (in my case is MacOS).
