Gulp has removed the 4.0 branch from their GitHub repository, so the previous way of installing using <code>npm install gulpjs/gulp.git#4.0 --save-dev</code> no longer works.

They state in their <a href="https://github.com/gulpjs/gulp#installation" rel="noreferrer">README</a> that the correct way to install gulp 4.0 is to run the command:

<code>npm install gulp@next</code>

Run the following to check the version of gulp cli that is installed on your machine. 

<pre><code>gulp -v
</code></pre>

If you are not running version 4, do the following to install gulp globally on your machine.

<pre><code>npm uninstall -g gulp
npm install -g "gulpjs/gulp#4.0"
</code></pre>

Now install gulp 4 locally

<pre><code>npm uninstall gulp --save-dev
npm install "gulpjs/gulp#4.0" --save-dev

to install gulp-4, CLI version has to be 1.2.2 which will support gulp 4.0

to install gulp-cli 1.2.2 run <code>sudo npm install gulp-cli@1.2.2 -g</code>

and to install gulp 4.0 run <code>npm install 'gulpjs/gulp.git#4.0' --save-dev</code>

when you run gulp -v command

My installation was a bit different.

Running 

<pre><code>npm install 'gulpjs/gulp.git#4.0' --save-dev
</code></pre>

Or

<pre><code>npm install 'gulpjs/gulp#4.0' --save-dev
</code></pre>

Gave me an error: 

<blockquote>
 npm ERR! code EINVALIDTAGNAME npm ERR! Invalid tag name "gulp#4.0": Tags
 may not have any characters that encodeURIComponent encodes.
</blockquote>

NB I was only having problems installing my local gulp-4 so I took a look at my last <code>package.json</code> installation and saw this: 

<pre><code>"gulp": "github:gulpjs/gulp#4.0",
</code></pre>

So my move was to install local gulp with

<pre><code>npm install "github:gulpjs/gulp#4.0" --save-dev
</code></pre>

and that worked, installing local gulp 4 successfully.

<pre><code>[15:45:55] CLI version 1.4.0
[15:45:55] Local version 4.0.0-alpha.2

I wrote a batch file that does the job based on what @demisx answered.

The problem I had was a missing npm config parameter 'prefix', so my global directory was the node binary directory.
I am pretty sure this wasn't always the case, but I could (re-)set it running this script from the project root directory:

<pre><code>@ECHO OFF
echo configuring npm
set USERNAME=&lt;enter username&gt;
set USERPROFILE=C:\Users\%USERNAME%
set APPDATA=%USERPROFILE%\AppData\Roaming
call npm config set prefix %APPDATA%\npm

SET DIR_PROJECT="D:/stuff/plugins/wallpaper_engine/raintime-dev"

echo Uninstall previous Gulp installation and related packages, if any
call npm rm gulp -g
call npm rm gulp-cli -g

echo cd %DIR_PROJECT%
cd /D %DIR_PROJECT%

call npm rm gulp --save-dev
call npm rm gulp --save
call npm rm gulp --save-optional
call npm cache clean

echo Install the latest Gulp CLI tools globally
call npm install gulpjs/gulp-cli -g

echo Install Gulp 4 into your project from 4.0 GitHub branch as dev dependency
rem call npm install gulpjs/gulp#4.0 --save-dev
call npm install gulpjs/gulp --save-dev

echo Check the versions installed.

call gulp -v

pause
</code></pre>

The script finally showed this:

<pre><code>[14:59:48] CLI version 2.0.1
[14:59:48] Local version 4.0.0
</code></pre>

Hope it helps!

I've been using gulp-watch. The current version of gulp-watch relies on the call gulp.parrallel. This call is only available from gulp 4.

However gulp 4 is not available via the npm repo. 
<code>npm info gulp dist-tags</code> returns: <code>{ latest: '3.9.0' }</code>.

I can see that there is a 4.0 branch within the git repo. But attempting to install it with variations on this command fails: <code>npm install https://github.com/gulpjs/gulp#v4.0.0</code>.

How do I install gulp 4

我一直在用大口手表。当前版本的gulp watch依赖于call gulp.parrallel。此呼叫仅在gulp 4中可用。但是，gulp 4不能通过npm repo获得。npm info gulp dist-tags返回：{ latest: '3.9.0' }。我可以看到在git代码库中有一个4.0分支。但尝试使用此命令的变体安装它会失败：npm install https://github.
