无法定位 .NET Core SDK

如何解决无法定位 .NET Core SDK

在运行 macos big sur 的 macbook 上的 vscode 中，我无法在 vs 代码中使用带有 dotnet 核心的 c#，我不断收到此错误（链接到下面的图片）。我尝试了无数的事情，包括将进入核心的路径附加到 bash_profile 以及卸载和重新安装，但没有任何效果，如果您有任何解决方案，请告诉我，下面是错误图片和完整的 OmniSharp 日志

解决方法

我能够为所有 mac 用户找到解决方案。您需要做的就是将下面列出的两行添加到您的 bash_profile 文件中，一切都会顺利运行。如果您在这样做时遇到问题，请随时回复此答案，我将非常乐意为您提供帮助。

PS：请确保将 5.0.203 替换为您的 .NET sdk 版本

export MSBuildSDKsPath="/usr/share/dotnet/sdk/$(dotnet --5.0.203)/Sdks"
export MSBuildSDKsPath="/usr/share/dotnet/dotnet/sdk/$(dotnet --5.0.203)/Sdks"
