[BUG] No module named 'pkg_resources.extern'

### setuptools version



setuptools==70.0.0



### Python version



3.8.10



### OS



Windows 11



### Additional environment information



_No response_



### Description



I use PyInstaller and PyArmor to obfuscate my code and create an Executable out of it.

On a pipeline of mine, an error started to throw today:

```

Traceback (most recent call last):

  File "Lib\site-packages\PyInstaller\hooks\rthooks\pyi_rth_pkgres.py", line 16, in <module>

  File "PyInstaller\loader\pyimod03_importers.py", line 495, in exec_module

  File "pkg_resources\__init__.py", line 77, in <module>

ModuleNotFoundError: No module named 'pkg_resources.extern'

```



Inside this Pipeline I run `python -m pip install -U setuptools`. I.e., it uses the latest version of it.



I tested it locally and it happens with version 70.0.0 but not with version 69.5.1



### Expected behavior



Obfuscated Executable from PyArmor and PyInstaller is created.



### How to Reproduce



1. Create a virtual environment

2. Install pyinstaller[encryption]==4.* and pyarmor==7.*

3. `pip install tendo==0.2.*` (just for the matter of having some import on the main.py file) (for some reason, it works with tendo>=0.3.0)

4. Create a test.py 

    ```python

    import tendo.singleton

    

    def main():

        print("Hello World!")

    

    if __name__ == "__main__":

        me = tendo.singleton.SingleInstance()

        main()

    ```

5. Run `pyarmor pack .\test.py -x "--exclude .venv"`

6. Run the test.exe on `dist/test/`



### Output



```console

python -m pip install -U setuptools

pip install -U pyarmor==7.* pyinstaller[encryption]==4.*

pyarmor pack main.py

```



```console
