How to install Gulp 4
Gulp 4 is not released yet and if you cannot wait to get your hands on it, here is how to install Gulp 4.
Install Gulp globally
If you have a previous version of Gulp installed, uninstall it first. You might need run this command as an administrator or a superuser, depending on your system.
npm uninstall -g gulp npm install -g "gulpjs/gulp-cli#4.0"
On my machine (Linux Mint Rebecca), I had no problems continuing using Gulp < 4 after globally installing Gulp 4.
Add Gulp 4 to your repositories
If you use a previous version of Gulp (i.e. Gulp 3.8.x or earlier), remove it from the repositories you want to upgrade. Don't forget to specify
--save so your
package.json gets updated.
cd YOUR_REPO npm uninstall gulp --save-dev npm install "gulpjs/gulp#4.0" --save-dev
Possible issues uninstalling Gulp
On my machine, previous version of Gulp hadn't been properly removed and I started to get that error when trying to run Gulp:
/usr/local/lib/node_modules/gulp/bin/gulp.js:129 gulpInst.start.apply(gulpInst, toRun); ^ TypeError: Cannot call method 'apply' of undefined at /usr/local/lib/node_modules/gulp/bin/gulp.js:129:20 at process._tickDomainCallback (node.js:492:13)
What does this error trace tell use?
gulp.start() is no longer in Gulp 4 and shouldn't be called, and
gulp-cli package should be called rather than an old
I ran the following command:
ls -l $`whereis gulp`
And realise I still had an old Gulp file in a bin folder:
lrwxrwxrwx 1 root root 40 May 3 11:17 /usr/bin/gulp -> ../lib/node_modules/gulp-cli/bin/gulp.js lrwxrwxrwx 1 root root 40 May 3 11:17 /usr/bin/X11/gulp -> ../lib/node_modules/gulp-cli/bin/gulp.js lrwxrwxrwx 1 root root 36 Apr 3 21:41 /usr/local/bin/gulp -> ../lib/node_modules/gulp/bin/gulp.js
Simply remove old files and you will be good to go:
$ sudo rm /usr/local/bin/gulp $ sudo rm -rf /usr/local/lib/node_modules/gulp
