You can try starting with Manual:How to debug.
The same problem happened to me. I had forgotten the installation of php-curl.
Hmm, that's rather annoying, composer should check such things really. @Jdforrester (WMF) is it true that visual editor depends on the php-curl extension ?
Yes, MediaWiki's multi-http-request whatever has required curl since it was written in ~ 2011, and VisualEditor (technically, MediaWiki's way of talking to Parsoid) is built on that. This is the first answer in Extension:VisualEditor#Troubleshooting for that reason.
@Jdforrester (WMF), we could add a composer file that declares the php curl requirement perhaps ? (i'm guessing that curl is an optional requirement for core.. in which case it should be a 'suggest' for core btw.... )
