.net Msbuild try 构建 msbuild.exe 而不是我的 .csproj 文件

我对在虚拟机上安装msbuild有问题.

我正在使用:

• Visual Studio 2022社区版
• .NET框架v4.8.1
• MSBuild版本MSBuild version 17.5.0+6f08c67f3 for .NET Framework - 17.5.0.10706
• Windows 10

如果我创建一个全新的"Hello World"C#项目(.Net Frameworkv4.8.1)，那么它将不会构建.

Visual Studio shows an error at the top:

错误是:

如果我try 在Visual Studio中从Developer powershell运行msbuild，则会出现以下错误:

> msbuild .\ConsoleApp2.csproj
MSBuild version 17.5.0+6f08c67f3 for .NET Framework
MSBUILD : error MSB1008: Only one project can be specified.
    Full command line: '"C:\PROGRA~1\MIB055~1\2022\COMMUN~1\MSBuild\Current\Bin\amd64\MSBuild.exe" "C:\Program Files\Microsoft Visual Studio\2022\Community\\MSBuild\Current\Bin\amd64\MSBuild.exe" .\ConsoleApp2.csproj'
  Switches appended by response files:
'' came from 'C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Current\Bin\amd64\MSBuild.rsp'
Switch: .\ConsoleApp2.csproj

For switch syntax, type "MSBuild -help"

这看起来很奇怪，它看起来像是试图运行命令. 在那里，它把自己作为自己的一个论点插入其中.

"C:\PROGRA~1\MIB055~1\2022\COMMUN~1\MSBuild\Current\Bin\amd64\MSBuild.exe" "C:\Program Files\Microsoft Visual Studio\2022\Community\\MSBuild\Current\Bin\amd64\MSBuild.exe" .\ConsoleApp2.csproj

如果我试图只运行msbuild，看起来msbuild试图构建msbuild.exe，但显然失败了.

我不知道这额外的msbuild美元是从哪里来的.

我试过了:

• 重新安装Visual Studio 2022
• 判断环境变量-一切正常
• 已判断文件C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Current\Bin\amd64\MSBuild.rsp-它仅包含默认注释

如何修复msbuild个项目，以便它可以再次建设项目？
