epub generation fails with the sample project about ibis-next

[johnblommers]

Aha, excellent! All I had to do was type:

sudo apt install php-xml

and ePub generation completed with success.

Hi @johnblommers thank you for the feedback. Really appreciated.
This tool uses DOMDocument in the process for converting markdown.
So DOMDocument is a dependency, and DOMDocument is shipped with a specific PHP Extension:
https://www.php.net/manual/en/dom.requirements.php

You need to install php-xml extension (or php-dom , in some operating system you have php-dom).

I will open a PR to set all the extension needed in the composer.json in order to provide a better message in the case the extension is missed.

You can run

composer check-platform-reqs

to see if something is missing.

If everything is fine you should see something like this:

ext-ctype    *          success provided by symfony/polyfill-ctype
ext-dom      20031129   success
ext-filter   8.3.2      success
ext-gd       8.3.2      success
ext-json     8.3.2      success
ext-mbstring *          success provided by symfony/polyfill-mbstring
ext-zlib     8.3.2      success
php          8.3.2      success

Great, I am happy to know that you updated your environment. I just merged a PR to set all the ext-* dependencies in the composer.json file #20
