I suppose there are no known tricks beyond installing pip-tools into the project's virtualenv to convince it to consider a specific python version?

[strong falcon]

Yeah, It's general advice to have pip-tools installed in your venv. However, you can also use globally installed pip-tools (or installed via pipx) -- there should be no difference for pip-compile. Globally installed pip-sync would require --python-executable option to point a specific python interpreter.

to convince it to consider a specific python version

To use specific python version, yeah, pip-tools should be installed there so that pip-compile could resolve deps in this environment.

AFAIK there are no other options to convince pip-compile to use a particular Python version.

(beyond ^^, I use n global installed pip-compiles named pip-compile-<version> which are installed to venvs corresponding to each version)

--pip-args='--python-version=3.7' should do the trick

[elfin glen]

@clear salmon i thought so, sadly not 😦

@elfin glen could you check this PR https://github.com/jazzband/pip-tools/pull/1898 ?

PR that makes pip-compile 1.6x faster for me https://github.com/pypa/pip/pull/12204

Awesome improvement! I can confirm it makes slightly faster pip-compile 🚀

@abstract stump is everything allright? xD

i don't quite get the all extras logic in pip-compile. if there are multiple src_files, we don't collect extras from all of them, since we reassign extras. but the good news is that this will fail loudly if it's a real bug

noticed this while making https://github.com/jazzband/pip-tools/pull/1964 (this will be a nice speed improvement for the repo i work in, let me know if it's not viable for some reason)

[strong falcon]

that's likey a bug, I've noticed the same recently, but haven't reported an issue yet.

[strong falcon]

I like the idea. Should be huge speed improvement!

@abstract stump we're focused on this right now https://github.com/jazzband/pip-tools/pull/1681 which seems related to your PR. After this being merged I'd gladly help with test and review.
