I'm trying to set default `interpreter_constraint`...
# general
q
I'm trying to set default `interpreter_constraint`s and `resolve`s for different apps in a monorepo, using BUILD files in the root folder for each app. Trying to follow this https://www.pantsbuild.org/docs/targets#field-default-values The BUILD files in each app folder look like this:
Copy code
__defaults__({
    (python_sources, python_tests): {
        "interpreter_constraints": ["3.11.5"],
        "resolve": "weather"
    }    
})
But it's not working. I get: 
UnrecognizedResolveNamesError: Unrecognized resolve name from the field 'resolve' in the target...
for a file in a subfolder. Am I doing something wrong here?
b
Could you share your 
pants.toml
? Or at least the sections related to python and resolves?
q
Copy code
[GLOBAL]
pants_version = "2.17.0"
backend_packages = [
    "pants.backend.build_files.fmt.black",
    "pants.backend.python",
    "pants.backend.python.lint.black",
    "pants.backend.experimental.python.lint.ruff",
    "pants.backend.experimental.python.typecheck.pyright"
]

[source]
root_patterns = [ "src", "tests" ]

[python]
# Python version can be overridden for a component in the component's BUILD file.
interpreter_constraints = ["3.11.5"]
enable_resolves = true

[python.resolves]
weather = "components/weather/dependencies/requirements.lock"

[pyright]
version="pyright@1.1.326"

[test]
use_coverage = true

[coverage-py]
report = "html"
output_dir = "coverage_report"
global_report = true
'component' == 'app'
b
okay. Nothing leaping out to me there. You might have to debug it by narrowing it down to a minimal example? E.g. hopefully it reproduces with one app/one python file?
q
Okay will do, thanks :)
c
can you share the full error message (with only sensitive parts redacted)?
e
So, it doesn't seem like it would explain the particular error message, but in both cases - 
pants.toml
and the 
__defaults__
- 
interpreter_constraints = ["3.11.5"]
is completely bogus. The constraint must be a specifier string like 
"==3.11.5"
, for example. There must be an operator.
Unless Pants has grown some "convenience feature" and translates a thing that looks like a version number into an 
==<version number>
for you?
Pex will say something like this if not:
Copy code
$ pex --interpreter-constraint 3.11.5
