Hi @enough-analyst-54434 . Thanks for the effort on making it clearer. I think I was not clear on the cases I ran as well. Please find the summary below: Use Case 1

requirements.txt

used to generate the lockfile

Copy code

dep-a ==4.2.31 #

dep-a

v 4.2.31 , in the

setup.py

'python_requires': '>=3.7.0,<3.8.0'

Results: I was playing just changing the

interpreter_constraints

✅ lockfile generated, ❌ fails to generate the lockfile with error:

ERROR: No matching distribution found for dep-a==4.2.31

1. If

pants.toml.[python].interpreter_constraints = ["==3.7.11"]

, ✅ 2. If

pants.toml.[python].interpreter_constraints = ["==3.7.*"]

, ✅ 3. If

pants.toml.[python].interpreter_constraints = [">=3.7.11"]

, ❌ Use Case 2 requirements.txt
used to generate the lockfile

Copy code

dep-a ==4.2.32

dep-a

v 4.2.32 , in the

setup.py

'python_requires': '>=3.7.*1*,<3.8.0'

Results: I was playing just changing the

interpreter_constraints

✅ lockfile generated, ❌ fails to generate the lockfile with error:

ERROR: No matching distribution found for dep-a==4.2.32

1. If

pants.toml.[python].interpreter_constraints = ["==3.7.11"]

, ✅ 2. If

pants.toml.[python].interpreter_constraints = ["==3.7.*"]

, ❌ 3. If

pants.toml.[python].interpreter_constraints = [">=3.7.11"]

, ❌ So based on the that, why does it have different results when setting

interpreter_constraints

"==3.7.11"

and

">=3.7.11"

? I agree, seems to be a
pex
issue indeed. I will create an issue there to iterate over this.
