Visual Studio Task Runner Error with ES6
I am running Visual Studio 2017 and use the Task Runner to run tasks in my gulpfile. I recently updated a gulp task to ES6 and now am getting this error:
Failed to run "C:\Users\nz9rcn\Code\WebUI\Gulpfile.js"...
cmd.exe /c gulp --tasks-simple
C:\Users\nz9rcn\Code\WebUI\gulp-tasks\lesslint.js:5
let fail = false;

Can’t find a place to adjust the settings causing this error (strict mode). Please help. Thanks
Issue solved by un-checking the box for the Node.js binary used by Task Runner:
In the menu, go to Tools > Options > Projects and Solutions > Web Package Management > External Web Tools and DESELECT the option for $(VSINSTALLDIR)\Web\External
The version installed in that directory doesn’t support ES6 apparently.
