There are a number of things in our repo that still require the use of a venv. I'm curious if I could use the power of

export

to reduce our bootstrap times. This bootstrapping does something like

pip install -U -e . -r requirements.txt -c constraints.txt

. Even with a warm pip cache, this takes usually around 2 minutes or so while

./pants export

is only like 15 seconds. The missing details are that the venv written by

export

sensibly doesn't have the

-e .

install step. Anyone tried to do something like this before?

2.11 has added support for VCS requirements, if you are using PEX lockfiles.

and

./pants export

now includes pip in the venv as of 2.11. (Although you may hit a bug when you're running with how interpreter constraints are chosen. Some people got it, some did not reproduce. The fix has been cherry picked and we will probably do a release this week)

Not pex lockfiles. Just in our

requirements.txt

for right now.
