找不到所需的库libhostfxr.so。Netcore

❯ 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
~ 如果在运行命令后没有运行，那么我能做什么呢？

通过将此添加到shell配置文件的任何部分(可以在末尾)解决这个问题：
# 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其中一个文件中：
- Bash Shell：~/.bash_profile，~/..bashrc
- Korn：~/..kshrc还是.profile
- Z壳：~/..zshrc或.zprofile
不要忘记关闭和打开终端，这样env变量就可以加载.
要检查是否一切正常，请运行dotnet ef，您应该得到如下内容：
❯ dotnet ef
_/\__

尝试更新下面的配置，并使用dotnet的最新版本：
export PATH="$PATH:$HOME/.dotnet/tools"
export DOTNET_ROOT=/snap/dotnet-sdk/current
export MSBuildSDKsPath=$DOTNET_ROOT/sdk/$(${DOTNET_ROOT}/dotnet --version)/Sdks
export PATH="${PATH}:${DOTNET_ROOT}"
export PATH="$PATH:$HOME/.dotnet/tools"页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
