How to install RenanBr/bibtex

[Walt K]

Trying to install the plugin on a fresh typo3 installation.
Plugin is installed over the extension manager (v 2.3.0)

When using the bib importer the following error

Oops, an error occurred! Class 'RenanBr\BibTexParser\Parser' not found

Presumably also this package should be installed: https://github.com/renanbr/bibtex-parser

Could you elaborate on this in the manual for the installation?

Please look at https://github.com/in2code-de/publications#technical-requirements - this extension needs to be installed in composer mode only. In classic mode third party packages are not loaded.

I just had the same problem, local is composer and live unfortunately not.
The dirty way was to copy the renarn directory from the vendor (local installation) to typo3conf/ext (live installation) and create an ext_emconf.php.

the important part

    'autoload' => [
        'psr-4' => [
            'RenanBr\\BibTexParser\\' => 'bibtex-parser/src/'
        ]
    ]

After installing the renan extension in backend (TYPO3 10.4.21), the import is working.
