MAC 上的 dotnet tool install --global dotnet-ef --version 3.0.0 导致未知 Nuget 错误

Question

在我的 Web API 项目中升级到 .Net Core 3.1 后，我尝试了这个常用的 ef 命令 -

dotnet ef

得到：

Could not execute because the specified command or file was not found.

Possible reasons for this include:
  * You misspelled a built-in dotnet command.
  * You intended to execute a .NET Core program, but dotnet-ef does not exist.
  * You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.

然后找到了这个 - dotnet ef not found in .NET Core 3

因此，尝试了：

dotnet tool install --global dotnet-ef --version 3.0.0

得到：

/usr/local/share/dotnet/sdk/3.1.100/NuGet.targets(123,5): error : Unable to load the service index for source https://api.nuget.org/v2/index.json 
/usr/local/share/dotnet/sdk/3.1.100/NuGet.targets(123,5): error :   Response status code does not indicate success: 400 (Bad Request). 
The tool package could not be restored.
Tool 'dotnet-ef' failed to install. This failure may have been caused by: ...

如何解决？

Answer 1

找到这个 -

Nuget connection attempt failed "Unable to load the service index for source"

所以，然后在 MAC 上打开 Nuget.config -

~/.nuget/Nuget/Nuget.config

并从那里删除所有网址。

重新运行

dotnet tool install --global dotnet-ef --version 3.0.0 

工作:)

在 VS for MAC 项目中重用 NUGET（刚刚添加了任何 Nuget），我只剩下

<configuration>
    <packageSources>
        <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <packageSources>
</configuration>

终于实现了使用ef tools 3.0.0，所以用-完成了ef tools的更新

dotnet 工具更新--global dotnet-ef
