Trying to run https://github.com/WebKit/WebKit/pull/17351 I've run into: Downloading dnslib-0.9.23... Installing dnslib-0.9.23...

Seemingly, setuptools is checking that requirements are satisfied for installed distributions, and finding that they in fact are not. This is because the AutoInstaller doesn't pay any attention to requirements whatsoever, and we merely rely on the distribution later importing another package we know of (and then installing it then) or via implicit_deps.

This seems to be happening within: EntryPoint.parse('setuptools_scm = setuptools_scm.integration:infer_version') Likely a regression from bug 261893?

(Or rather, this specific instance of the bug is caused by that — the underlying problem of not installing requirements has existed as long as the autoinstaller.)

(In reply to Sam Sneddon [:gsnedders] from comment #2) > (Or rather, this specific instance of the bug is caused by that — the > underlying problem of not installing requirements has existed as long as the > autoinstaller.) This specific instance was solved by https://bugs.webkit.org/show_bug.cgi?id=262184. See also: bug 265809, bug 262182, and bug 262154 for other cases of this. pip guarantees that all dependencies are installed before their dependents, and we should probably guarantee this too. Most of the time this isn't a concern because we end up soon installing them when they are imported from the newly installed installation package, but because there are times where libraries check they are actually installed.
