NPM错误!错误:enoent“…\<non existing folder>\package.json”

遵循本指南: https://docs.microsoft.com/en-us/aspnet/core/client-side/spa/angular?view=aspnetcore-2.2&tabs=visual-studio

我已经跑了 dotnet new angular -o HelloWorld ,然后在Visual Studio中打开.csproj。

接下来,我运行生成过程并开始调试,现在面临aggregateexception错误:

AggregateException: One or more errors occurred. (One or more errors occurred. (The NPM script 'start' exited without indicating that the Angular CLI was listening for requests. The error output was: npm ERR! Error: ENOENT, open 'E:\DELETEME\HelloWorld\ClientApp\node_modules\start\package.json'

值得注意的: package.json 文件实际位于 E:\DELETEME\HelloWorld\ClientApp\package.json , 不是 E:\DELETEME\HelloWorld\ClientApp\node_modules\start\package.json

有关版本的一些详细信息:
