solution:
Directly open the installation path of Visual Studio extension components, for example: My Visual Studio 2010 is installed on the D drive, so the installation path of extension components is D:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft Corporation . Delete the entire directory of NuGet Package Manager under the Microsoft Corporation directory, restart Visual Studio 2010, and you will not see the NuGet Package Manger component in the extension manager, and now you can reinstall the NuGet Package Manager component.
Finally successfully installed the latest version of the NuGet component and the problem has been resolved.
