I'm having the same issue (with slightly different version of monolog i.e. 2.0.0).

./composer.json has been updated
Loading composer repositories with package information

I see this issue was resolved but I think this change of composer.json caused the problem - 7097f0d

Hi @WiktorPacer

Yes that one caused the issue. Please use the latest version of the library where we don't require a specific version of the monolog anymore. If you would still keep using the one which you are using now just change the composer.json as a quick fix, that will work as well.

Best,
