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 _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This error seems to be caused by an out of date cli version of gulp.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.

Solution

  • 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)
