Hey, I'm trying to migrate from the old tool lockfiles to the new way but am getting the following error:

InvalidLockfileError: You are consuming `isort[colors,pyproject]<6.0,>=5.9.3` from the `toolshed` lockfile at 3rdparty/python/toolshed.lock with incompatible inputs.



- The inputs use interpreter constraints (`CPython<4,>=3.7`) that are not a subset of those used to generate the lockfile (`CPython==3.8.* OR CPython==3.9.*`).

- The input interpreter constraints are specified by your code, using the `[python].interpreter_constraints` option and the `interpreter_constraints` target field.

- To create a lockfile with new interpreter constraints, update the option `[python].resolves_to_interpreter_constraints`, and then generate the lockfile (see below).

See <https://www.pantsbuild.org/v2.16/docs/python-interpreter-compatibility> for details.

To regenerate your lockfile, run `pants generate-lockfiles --resolve=toolshed`.

See <https://www.pantsbuild.org/v2.16/docs/python-third-party-dependencies> for details.

However. when I run

pants py-constraints ::

I get the following:

Final merged constraints: CPython==3.8.*,==3.9.*

Everything in my repo is running either Python 3.8 or 3.9 so not sure which input it is complaining about

if you run

./pants help-advanced isort

you will see the interpreter for isort, if you didn't override those anywhere they will be the default, which is

CPython>=3.7,<4

so the workaround might require you to override this value in your pants.toml file.

This should be fixed in rc2/rc3 though - it will take the ICs from the lockfile

I'm getting this error when trying to upgrade to rc3 ->

Whoa

Yes to the first one, unsure on the last one

When you run Pants, is it via

pants

(the new launcher binary) or

./pants

(the old launcher script)?

the former

Great, so that is the new launcher

oh I just figured it out - this only occurs when I have a virtualenv activated

Oh, you should never do that

Yeah, I had a virtualenv I exported activated and didn't realize that was interfering

Now back to the lockfile update 🙂
