If you use Codeception installed using composer, install this module with the following command:

{% highlight yaml %} composer require --dev codeception/module-cli

{% endhighlight %}

Alternatively, you can enable Cli module in suite configuration file and run

{% highlight yaml %} codecept init upgrade4

{% endhighlight %}

This module was bundled with Codeception 2 and 3, but since version 4 it is necessary to install it separately.
Some modules are bundled with PHAR files.
Warning. Using PHAR file and composer in the same project can cause unexpected errors.
