Probably a caching issue on your failing host.

[alcohol]

But I cannot reproduce it myself.

Probably duplicate of #7603 which should be resolved by now. See my last comment there for instructions if you still see the problem: #7603 (comment)

Just an FYI for anyone else coming across this issue, i.e. even the new 5.6.10 version; make sure you have all your dependencies installed for PHP. I was missing a few and after going through the list.
After I had all the packages installed, I re-entered "sudo composer create-project grumpydictator/firefly-iii --no-dev --prefer-dist firefly-iii 5.6.10" and it went through no issues.
