启动 VS 15.3.1 时,我在活动日志中看到此错误。它似乎与 PVS 工作室有关,因为当我禁用扩展时它就消失了。

我只使用 C#,所以我没有安装任何 c++ 模块。单击确定消息后,我没有遇到任何其他异常。

我尝试禁用所有其他第三方扩展并重新启动 VS,并在启动时打开以下窗口:

  • C# 交互式
  • 错误列表
  • 任务列表
  • 命令窗口
  • 输出
  • 测试资源管理器
  • 解决方案资源管理器
  • 团队资源管理器
  • 首页

然后启用 PVS 并重新启动 VS:我收到错误消息

“Visual C++ 项目系统包”未正确加载。

然后我删除了组件缓存文件夹:我仍然收到错误。

使用ClearMEFComponentCache清理。重新启动PVS,现在我无法重现。

其他信息:我已经升级到 VS 15.3.2

  • 在运行 ClearMEFComponentCache 之前,我有几个文件夹%appdata%\Microsoft\VisualStudio,即14.015.0以及15.0_aaea4580文件ComponentCache夹所在的文件夹。现在我只有15.0_aaea4580文件夹。
  • VS 在管理员模式下打开。

不幸的是,我们目前无法重现该问题。或者,更准确地说,我们无法按照您的情况可能出现的方式重现它。通过为 devenv.exe 进程指定错误的 MSBUILD_EXE_PATH 环境变量值,我们能够导致 Visual C++ IDE 包失败,但您的情况很可能是不同的情况。

您能否详细说明当您启动 Visual Studio 并在您提供的活动日志中出现错误时会发生什么 - IDE 会崩溃吗?它的某些组件是否无法正确加载?如果 IDE 运行没有问题,您可以忽略日志中的警告。如果有问题,请尝试删除 %UserProfile%\AppData\Local\Microsoft\VisualStudio\<Visual Studio Version> 目录中的 'ComponentModelCache' 文件夹。
