.net core aspnet codegenerator标识列表选项导致脚手架失败错误

浏览本教程

我所做的一切都是按照书面形式进行的，因此以下是复制的步骤：

创建一个.net核心项目（名为“DotNetCorePlayed”，VS2019）

从package manager控制台运行以下命令：

dotnet工具安装-g dotnet aspnet codegenerator

以及：

dotnet添加dotnetcoregraphy包Microsoft.VisualStudio.Web.CodeGeneration.Design
dotnet添加DotNetCore游乐场包Microsoft.EntityFrameworkCore.Design
dotnet添加DotNetCore游乐场包Microsoft.AspNetCore.Identity.EntityFrameworkCore
dotnet添加DotNetCore游乐场包Microsoft.AspNetCore.Identity.UI
dotnet添加DotNetCore游戏包Microsoft.EntityFrameworkCore.SqlServer
dotnet添加DotNetCore游戏包Microsoft.EntityFrameworkCore.Tools

一切都按预期进行，结果是：

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="3.1.3" />
    <PackageReference Include="Microsoft.AspNetCore.Identity.UI" Version="3.1.3" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="3.1.3">
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
      <PrivateAssets>all</PrivateAssets>
    </PackageReference>
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="3.1.3" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="3.1.3">
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
      <PrivateAssets>all</PrivateAssets>
    </PackageReference>
    <PackageReference Include="Microsoft.VisualStudio.Azure.Containers.Tools.Targets" Version="1.10.8" />
    <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="3.1.2" />
  </ItemGroup>

结果是：

dotnet : Scaffolding failed.
At line:1 char:1
+ dotnet aspnet-codegenerator identity -h p C:\Users\[user]\sou ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (Scaffolding failed.:String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError

Could not find project file in C:\Users\[user]\source\repos\DotnetCoreplayGround

知道为什么找不到项目文件吗？

我尝试运行：

dotnet aspnet codegenerator-help

和got脚手架失败错误。 问题是我的

.config

文件夹被删除了（我不知道为什么）

我是如何解决问题的：

我在其中创建了一个新的

.config

文件夹和一个新的

dotnettools.json

文件

文件内容：

{
  "version": 1,
  "isRoot": true,
  "tools": {
    "dotnet-ef": {
      "version": "3.1.3",
      "commands": [
        "dotnet-ef"
      ]
    },
    "dotnet-aspnet-codegenerator": {
      "version": "3.1.1",
      "commands": [
        "dotnet-aspnet-codegenerator"
      ]
    }
  }
}

然后转到终端并运行dotnet工具还原

---

就这样

你找到解决办法了吗？嘿，AnatolyNikolaev，恐怕没有

{
  "version": 1,
  "isRoot": true,
  "tools": {
    "dotnet-ef": {
      "version": "3.1.3",
      "commands": [
        "dotnet-ef"
      ]
    },
    "dotnet-aspnet-codegenerator": {
      "version": "3.1.1",
      "commands": [
        "dotnet-aspnet-codegenerator"
      ]
    }
  }
}
