Hi! I encountered this error when upgrading pants:

[WARN] /home/cedriczheng/.cache/pants/setup/bootstrap-Linux-x86_64/1.23.0_py36/lib/python3.6/site-packages/pex/pep425tags.py:274: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses

):

Thanks @happy-kitchen-89482 for pointing out I should fix the

importlib-metadata

version to

2.1.3

. But I don’t know which package depends on it. How do I pin the version? I added

importlib-metadata==2.1.3

in requirement.txt, but it did not work.

What command are you running?

I was running ./pants test …

OK

Sure

you're running ./pants binary? what version was it before vs now? i wonder if the version of setuptools changed

@freezing-area-97131 what does your `pants.ini`'s

[pytest]

section look like?

right now the

[pytest]

in

[pants.ini]

is like this:

[pytest]
requirements: pytest>=4.6.6,<4.7
unittest2_requirements = coverage==5.2.1

Try adding

pytest_plugins = "+['importlib_metadata==2.1.3']"

oh Great! I changed it to this:

[pytest]
pytest_plugins = +["importlib_metadata==2.1.3", "pytest>=4.6.6,<4.7", "coverage==5.2.1"]

And I got a different error message now. I will try figure it out by myself first.
