Visual Studio 2015社区 - "Visual C++项目系统包"错误

Question

所以,我一直有这个问题.通常,当我尝试打开任何项目时,我会收到以下错误:

---------------------------
Microsoft Visual Studio
---------------------------
The 'Visual C++ Project System Package' package did not load correctly.



The problem may have been caused by a configuration change or by the
installation of another extension. You can get more information by examining the
file 'C:\Users\Q009\AppData\Roaming\Microsoft\VisualStudio\14.0\ActivityLog.xml'.



Restarting Visual Studio could help resolve this issue.



Continue to show this error message?

打开活动日志会显示以下错误:

SetSite failed for package [Visual C++ Project System Package][Object reference not set to an instance of an object.]:{ at Microsoft.VisualStudio.Project.VisualC.VCProjectEngine.VCProjectEngineShim.get_ProjectService() at Microsoft.VisualStudio.Project.VisualC.VCProjectEngine.VCProjectEngineShim.Initialize(IntPtr instResources, Object sp, Object browser, IVCBuildPackageInternal bldPkg)}

为了"解决"这个问题,我只需要去AppData/Local/Microsoft并删除VisualStudio和VSCommon文件夹.这修复了一段时间,让我继续我的项目工作.直到问题随机决定再次回来.

再次,澄清情况.这不是迁移问题或新安装的软件包的问题.我已经有一段时间了这个设置,这些项目是使用这个Visual Studio实例创建的.

我时不时地得到同样的错误而不仅仅是C++项目.解决方案各不相同,但大部分时间都是通过删除ComponentModelCache下的文件来完成的,正如WhozCraig建议的评论:

rmdir /q /s %LOCALAPPDATA%\Microsoft\VisualStudio\14.0\ComponentModelCache

更新:

现在存在一个扩展,清除了由Mads Kristensen编写的VS 2015,2017的ComponentCache.
