Visual Studio Task Runner "SyntaxError: Use of const in strict mode."

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:






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.

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).
