Visual Studio Task Runner“SyntaxError：在严格模式下使用const”。 [英] Visual Studio Task Runner "SyntaxError: Use of const in strict mode."

问题描述

使用Win10 Pro / VS2015与'网站'项目（不是asp.net，基本网站）

当试图保存/重新加载gulpfile.js时，我收到错误消息（来自Task Runner Explorer / output）
$ b

SyntaxError：在严格模式下使用const。

在目前的情况下，它正在扼杀'gulp-changed'

I已经浏览了可用的答案和评论：

• 
  在我的情况下，环境路径$（PATH）已经包含节点的全局安装，但我需要将它移动到$（ DevEnvDir）路径，以便获得优先权。
  
  
  

  （在提供正确答案后添加，谢谢@baao）

  $ b $ VS似乎会安装（然后使用）一个旧版本的节点，这就是为什么任务运行者打破构建。
  $ b
  $ b

  转至工具>选项>项目和解决方案>外部Web工具并将正确的路径添加到您的节点版本中（找到哪个节点）的路径。

  Using Win10 Pro / VS2015 with a 'website' project (not asp.net, basic website)

  When attempt to save/reload gulpfile.js I receive the error message (from Task Runner Explorer/output)

  SyntaxError: Use of const in strict mode.

  In the present case it is choking on 'gulp-changed'

  I have looked through the answers and comments available:

  • SyntaxError: Use of const in strict mode

  • SyntaxError: Use of const in strict mode?

    1. I have updated my version of node to the latest: 6.10.30
    2. I have cleaned the cache (npm cache clean -f)
    3. I have used 'which node' to determine that node is pointing to the installation of the latest install.
    4. "n" does not want to install on Windows (?)

  ---

  In my case the environment path, $(PATH) already include the global install of node but I needed to move it ahead of the $(DevEnvDir) paths so that it would get priority.

  (added after correct answer provided, thanks @baao)

  解决方案

  VS seems to install (and then use) an old version of node, which is why the task runner is breaking the build.

  Go to Tools > Options > Projects and Solutions > External Web Tools and add the correct path to your node version (find the path with which node).
