c# - 任务运行器资源管理器不工作

Question

我在 VS2015 社区中制作的项目中应用了 Gulp。但是当我使用 Task Runner Explorer 时，会出现一个对话框，提示“Exception has been throwed by the target of an invocation.”我尝试在“配置外部 Web 工具”中执行(PATH)操作但这根本没有帮助。

NPM 安装正常，Gulp 正常执行。

我正在使用以下版本

• .NET Framework 4.6.1
• Gulp v1.3.15
• npm v1.3.15
• 节点 v5.3.0

此外，当我运行项目并打开 Task Runner Explorer 时，出现以下异常:

An exception was encountered while constructing the content of this frame.  This information is also logged in "C:\Users\marvin\AppData\Roaming\Microsoft\VisualStudio\14.0\ActivityLog.xml".
Exception details:

我遇到了同样的错误，注意到我的 C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft\Web Tools 目录是空的。

通过重新安装 修复它 Microsoft ASP.NET and Web Tools 扩展。
