我尝试了很多事情，没有任何帮助：

• 我安装了.NET Core 2.0
• 我将软件包varsion更改为：1.0.4 in .csproj
• 我使用命令dotnet nuget locals -c all和之后dotnet还原

有人可以帮我吗？:)请

Answer 1

我在升级到15.6后遇到了这个问题。我能够通过将所有SDK暂时移至SDK文件夹（C：/Program Files/dotnet/SDK）来解决问题。运行dotnet还原，缓存人群成功，然后将SDK移回。

长期我们将寻求更新我们的global.json文件以固定较新的SDK，如先前的响应所示。

Answer 2

这是1.0的问题。* .net core sdk的版本（不是运行时！），它不再兼容一次与新的nuget版本中介绍的功能一旦设置了这些功能全局后备文件夹。

由于您似乎安装了2.0版本，因此可能有一个global.json文件固定SDK的旧版本。确保您要么固定1.1。*或2。* SDK的版本或根本不使用global.json文件。您仍然可以使用较新的SDK对准.NET Core 1.0。

Answer 3

我能够通过编辑global.json和替换来解决此问题：

"version": "1.0.0-rc4-004771"

with：

"version": "2.0.0"
