找不到任何已安装的.NET SDK

Question

我已经安装了多个版本的.NET Sdk。现在Omnisharp建议不能正常工作。

输出显示这些

[info]: OmniSharp.MSBuild.ProjectManager
        Loading project: /BO-V2/Techne-Travel/travel-techne-bo-for-ota/src/Application/Application.csproj

但是dotnet-info显示了这个输出

哪个网络命令

/usr/bin/dotnet

我在谷歌上搜索过，发现了这个https://www.py4u.net/discuss/1941159.

我按照他们说的做了下面的事。但我仍然面临着同样的问题。为什么会出现这个问题？我该如何解决setting.json

{
    "editor.formatOnSave": false,
    "editor.codeActionsOnSave": {
        "source.fixAll": false
    },
    "omnisharp.path": "latest",
}

omnisharp.json

{
    "MsBuild": {
        "UseLegacySdkResolver": true
    }
}

global.json

{
  "sdk": {
    "version": "6.0.101",
    "rollForward": "latestMinor"
  }
}

我应该怎么做才能使omnisharp工作正常？没有Omnisharp的建议，我无法继续工作。它很难编码。请帮帮我。

请参阅此处的文档https://github.com/OmniSharp/omnisharp-vscode

使用OmniSharp的.NET 6构建从C#扩展版本开始1.24.0，现在可以选择使用运行在.NET 6 SDK上的OmniSharp构建。此内部版本要求安装.NET 6 SDK并且不使用Visual Studio MSBuild工具或Mono。它只支持可通过dotnet构建的更新的SDK风格的项目。团结一致不支持项目和其他完整框架项目。

要使用.NET 6内部版本，请在VS中将omnisharp.useModernNet设置为true编码设置并重新启动OmniSharp。
