任务运行资源管理器不工作

我已经在VS2015社区中制作的项目上应用了Gulp。但是，当我使用任务运行资源管理器时，出现一个对话框，指出“异常已被调用的目标抛出。”我尝试在“配置外部Web工具”中执行（PATH）的事情，但它没有帮助。任务运行资源管理器不工作

NPM安装正在运行，Gulp正在正确执行。

我使用以下版本

的.NET Framework 4.6.1
咕嘟咕嘟v1.3.15
NPM v1.3.15
节点V5.3.0

此外，当我运行该项目并打开Task Runner Explorer时，我有以下例外情况：

我有同样的错误，并注意到我的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Microsoft ASP.NET and Web Tools扩展来修复它。

它也解决了我的问题！，tnx。只是一件事：尝试以这种方式从cmd运行此Web工具扩展： “DotNetCore.1.0.0-VS2015Tools.Preview2.exe SKIP_VSU_CHECK = 1”。（这会在安装前跳过对当前版本号的任何检查）。 – Dudi

如果可以帮助其他人，则无法从VS Extensions和Updates中卸载并重新安装。您需要下载扩展名exe并卸载并安装，或使用修复选项。 – gitsitgo
