使用Visual Studio 2019时如何在我的PATH中添加“ aspnet-codegenerator”？

Question

我正在使用Mac的Visual Studio 2019（8.6.3）。我有一个使用ASP.net核心的MVC应用程序。我安装了

Microsoft.VisualStudio.Web.CodeGeneration.Design

NuGet软件包。然后，按照一个教程（https://docs.microsoft.com/en-us/aspnet/core/tutorials/first-mvc-app/adding-model?view=aspnetcore-3.1&tabs=visual-studio-mac#add-a-data-model-class），我打开了一个命令窗口

，然后输入以下内容。但是，我得到了错误...

localhost:DemoMVCApp satishp$ dotnet aspnet-codegenerator controller -name MoviesController -m Movie -dc MvcMovieContext --relativeFolderPath Controllers --useDefaultLayout --referenceScriptLibraries
Could not execute because the specified command or file was not found.
Possible reasons for this include:
  * You misspelled a built-in dotnet command.
  * You intended to execute a .NET Core program, but dotnet-aspnet-codegenerator does not exist.
  * You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.

我还需要做些什么来安装/执行我的代码生成器？
