The PDF can't be built

[ghost]

I tried to build the PDF of the book but got the following error:

I just followed the steps of the provided readme.md file.

I am using Arch Linux and use the current version of php, composer and texlive in the repository.

What version of Yii do you have?

[ghost]

I can't really tell from the composer.json file of the project, but the changelog of the yii package goes up to version 2.0.10, so i guess this is the installed version. Is there a better way to get the version of the installed Yii framework?

Edit: The composer.lock file says version 2.0.10 is installed.

[samdark]

You need at least 2.0.13 to use it with PHP 7.

I could get it to work, but there were some steps needed beforehand:

1. Install the php-mcrypt extension as Yii2 needs it
2. Update the composer.json to the following:

   {
   "require": {
       "yiisoft/yii2": "~2.0.35",
       "yiisoft/yii2-apidoc": "~2.1.0",
       "bower-asset/jquery": "~3.4.1"
   },
   "repositories": [
       {
           "type": "composer",
           "url": "https://asset-packagist.org"
       }
   ]
   }

   After that i can run make but i still get an error:

   vendor/bin/apidoc guide --template=pdf --interactive=0 ../book/ ./pdf
   Updating cross references and backlinks... done.
   Searching files to process... done.
   Rendering markdown files: 35% (17/48) ETA: n/a   Error: array_unique() expects parameter 1 to be array, null given
   make: *** [Makefile:6: book.pdf] Fehler 1

   I am using Arch Linux with PHP 7.4 by the way.
