Hi~ Now I have upgraded to

1.25.0

, and got this error when running

./pants test …

. How do I find out which packages cause this conflict?

Exception message: Could not satisfy all requirements for pytest<4.7,>=4.6.6:
    pytest<4.7,>=4.6.6, pytest<5.4,>=5.3.5

That looks like a conflict between your

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

and Pants's default, which is set by

version

under

[pytest]

.

ok~ After I removed it and ran it again, I got this:

**** Failed to install pytest-5.3.5 (caused by: NonZeroExit("received exit code 1 during execution of `['/usr/bin/python2.7', '-s', '-', 'bdist_wheel', '--dist-dir=/tmp/tmpv4cu0fne']` while trying to execute `['/usr/bin/python2.7', '-s', '-', 'bdist_wheel', '--dist-dir=/tmp/tmpv4cu0fne']`",)

I think my whole repo is in python2.7. What should I do?

Well, the issue here is that it's still trying to install pytest-5.3.5 for some reason

Where should I put that line?
