❯ dotnet ef   
A fatal error occurred. The required library libhostfxr.so could not be found.
If this is a self-contained application, that library should exist in [/home/ru/.dotnet/tools/.store/dotnet-ef/6.0.2/dotnet-ef/6.0.2/tools/netcoreapp3.1/any/].
If this is a framework-dependent application, install the runtime in the global location [/usr/share/dotnet] or use the DOTNET_ROOT environment variable to specify the runtime location or register the runtime location in [/etc/dotnet].

The .NET runtime can be found at:
  - https://aka.ms/dotnet-core-applaunch?missing_runtime=true&arch=x64&rid=arch-x64&apphost_version=6.0.2

通过将其添加到髋臼杯轮廓的任何部分（可以在末端）解决：

# Netcore
export PATH=$PATH:$HOME/.dotnet/tools
export DOTNET_ROOT=$HOME/.dotnet
export PATH=$PATH:$DOTNET_ROOT

您的shell配置文件可以位于以下文件之一中：

哈希 shell ：~/.bash配置文件、~/.bashrc
Korn shell ：~/.kshrc或.profile
Z shell ：~/.zshrc或. z配置文件
不要忘记使用命令source ~/.bashrc（取决于您的shell配置文件），以便加载env变量。

要检查是否一切正常，请运行dotnet ef，您应该得到如下所示的结果：

❯ dotnet ef

               ---==/    \\      
         ___  ___   |.    \|\    
        | __|| __|  |  )   \\\   
        | _| | _|   \_/ |  //|\\ 
        |___||_|       /   \\\/\\

我在使用Snap version时遇到了这个错误（还有很多其他错误）。当我切换到Snap version时，这些问题都消失了。
