为什么我无法运行 dotnet tool install --global bla-bla-bla? [英] Why am I unable to run dotnet tool install --global bla-bla-bla?

问题描述

具体来说，我正在尝试运行 dotnet tool install --global Project2015To2017.Migrate2017.Tool 如此处所述 - https://github.com/hvanbakel/CsprojToVs2017#as-a-net-core-global-tool

Specifically, I am trying to run dotnet tool install --global Project2015To2017.Migrate2017.Tool as explained here - https://github.com/hvanbakel/CsprojToVs2017#as-a-net-core-global-tool

这是我得到的:

c:Program Filesdotnetsdk2.1.4SdksMicrosoft.NET.SdkuildMicrosoft.NET.TargetFrameworkInference.targets(135,5): error : The current .NET SDK does not support targeting .NET Core 2.1.  Either target .NET Core 2.0 or lower, or use a version of the .NET SDK that supports .NET Core 2.1. [C:UsersmkharitonovAppDataLocalTemp3sdfphfy.fq0
estore.csproj]
The tool package could not be restored.
Tool 'project2015to2017.migrate2017.tool' failed to install. This failure may have been caused by:

* You are attempting to install a preview release and did not use the --version option to specify the version.
* A package by this name was found, but it was not a .NET Core tool.
* The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
* You mistyped the name of the tool.

所以，我去了https://www.microsoft.com/net/download/dotnet-core/2.1 并安装了 SDK 2.1.500 的 .NET Core Installer x64.当这不起作用时，我为 Runtime 2.1.6 安装了相同的(不认为它做任何事情).无论如何，错误消息仍然存在，我不知道我应该做什么.

So, I went to https://www.microsoft.com/net/download/dotnet-core/2.1 and installed the .NET Core Installer x64 of SDK 2.1.500. When this did not work I installed the same for Runtime 2.1.6 (do not think it did anything). Anyway, the error message stays and I have no idea what am I expected to do.

推荐答案

您可以运行具有诊断详细级别的 dotnet 工具安装.例如:

You can run dotnet tool install with diagnostic verbosity level. For example:

dotnet tool install --global Project2015To2017.Migrate2017.Tool -v diag

我遇到了一些问题，就我而言，我遇到了错误:

I had some problem and in my case I had error:

The SDK 'Microsoft.NET.Sdk' specified could not be found

为了解决这个问题，我更改了环境变量 MSBuildSDKsPath(来自 https://github.com/Microsoft/msbuild/issues/2532)

To solve this problem I changed environment variable MSBuildSDKsPath (advice from https://github.com/Microsoft/msbuild/issues/2532)
