importlib.metadata.PackageNotFoundError: jsonschema

(Maybe related to #1068, closed yesterday)

When running a small script compiled in standalone mode, I get:

Traceback (most recent call last):
  File "[...]/test.dist/jsonschema_test.py", line 1, in <module>
  File "[...]/test.dist/jsonschema/__init__.py", line 34, in <module jsonschema>

importlib.metadata.PackageNotFoundError: jsonschema

Python installed with anaconda in dedicated environment.

$ python -m nuitka --version

0.6.15
Python: 3.9.5 (default, May 18 2021, 12:31:01)
Executable: /Users/mesca/anaconda3/envs/nuitka/bin/python
OS: Darwin
Arch: x86_64

I have the same issue when using the develop branch (v0.6.16rc1).

$ python -m pip freeze | grep jsonschema

jsonschema==3.2.0

Minimal example:

from jsonschema import validate

if __name__ == "__main__":
    schema = {
        "type" : "object",
        "properties" : {
            "foobar" : {"type" : "number"}
        }
    }
    validate(instance={"foobar": 42}, schema=schema)

Fixed on github develop, but there will be a hotfix for this soon.
