VSTS with gulp v.4.0.0

I'm having the gulp version of one of my projects. Previously we were using version 3.9.1 and we were hestitative updating.

After updating i have fixed all local issues and tested the project on a different computer (after updating the installed gulp there as well) it works fine.

Our automatic deployment however won't agree with me.

After a check-in our VSTS does the following steps

  1. install npm
  2. execute command
  3. build project

However, this produces the following error.

Working directory changed to D:\a\1\s\MVC
Using gulpfile D:\a\1\s\MVC\gulpfile.js
C:\NPM\Modules\node_modules\gulp\bin\gulp.js:129
gulpInst.start.apply(gulpInst, toRun);
     ^
     TypeError: Cannot read property 'apply' of undefined
at C:\NPM\Modules\node_modules\gulp\bin\gulp.js:129:20
at _combinedTickCallback (internal/process/next_tick.js:131:7)
at process._tickDomainCallback (internal/process/next_tick.js:218:9)

This error seems to be caused by an out of date cli version of gulp. But i can't figure out how to update this using VSTS.

Concrete problem

How do i update gulp cli in VSTS

What have i done already?

After some checking i saw the npm version installed was very old (3.10.8). I've dragged in a nodejs installer which updates to the latest version and gives me the latest version of nodejs, and a much newer version of npm (5.6.0) which i've used at on-hands computers to update the cli version. however i can't figure out how to do this in VSTS.

The solution that I found worked for me was to change the Pipeline from Hosted to Hosted VS2017.

I had completed a PR that upgraded the Gulp to 4.0, and the PR build completed but the CI build failed with strange results. After a lot of searching, I narrowed it down to the PR build already being set to Hosted VS2017 (it was building C# projects too that required them) and the CI build was only doing the Gulp build and was set to Hosted.

Try to install/update gulp-cli through NPM task:

BTW, the package in package.json will be installed on current project/folder instead of global, you need to call gulp command through npm command (scripts property of package.json) to use package in current project/folder or specify the path directly (e.g. ./node_modules/gulp/bin/gulp)

It seems that you are using Hosted Agent which the installed npm version is 3.10.8. You just need to add a Node Tool Installer task in your build definition and set it to use "8.x" version. It will install the 8.x version which include npm 5.6.0. enter image description here

npm version before Node Tool Installer task: enter image description here npm version after Node Tool Installer task: enter image description here
