When I ran

pants export ::

Sure, so Pex is trying to create a venv and it's running:

/Users/szto/.pyenv/versions/3.9.15/bin/python -m ensurepip -U --default-pip

That apparently hangs. Can you try running that manually?

➜  linear-cli git:(main) ✗ /Users/szto/.pyenv/versions/3.9.15/bin/python -m ensurepip -U --default-pip            
Looking in links: /var/folders/4y/2r8ypdnx6kv0t1vd71t6kd1h0000gn/T/tmpltwei0db
Requirement already satisfied: setuptools in /Users/szto/.pyenv/versions/3.9.15/lib/python3.9/site-packages (58.1.0)
Requirement already satisfied: pip in /Users/szto/.pyenv/versions/3.9.15/lib/python3.9/site-packages (22.3.1)

I ran the script but it is the same running export command

For full fidelity, try:

/Users/szto/.pyenv/versions/3.9.15/bin/python -mvenv pex.venv
pex.venv/bin/pip install pex==2.1.111
pex.venv/bin/pex -o empty.pex --include-tools
PEX_TOOLS=1 ./empty.pex venv test.venv --pip

it hangs~

Ok then, you have a good narrow case to dig on. I have no clue why it hangs.
