No module named 'pip' despite pip is installed in conda env

I've just got started on anaconda and I've been trying to clone this github repo https://github.com/THU-MIG/yoloe/.

after running the clone command and activating a required venv with python 3.10, all that remained was to install the requirements:

pip install -r requirements.txt

Ridiculously enough, this is what happened:

error: subprocess-exited-with-error × Getting requirements to build editable did not run successfully. │ exit code: 1 ╰─> [19 lines of output] Traceback (most recent call last): File "D:\ProgramData\anaconda3\envs\yoloe\lib\site-packages\pip\_vendor\pyproject_hooks\_in_process\_in_process.py", line 389, in <module> main() File "D:\ProgramData\anaconda3\envs\yoloe\lib\site-packages\pip\_vendor\pyproject_hooks\_in_process\_in_process.py", line 373, in main json_out["return_val"] = hook(**hook_input["kwargs"]) File "D:\ProgramData\anaconda3\envs\yoloe\lib\site-packages\pip\_vendor\pyproject_hooks\_in_process\_in_process.py", line 157, in get_requires_for_build_editable return hook(config_settings) File "C:\Users\jeffg\AppData\Local\Temp\pip-build-env-iyul_9eb\overlay\Lib\site-packages\setuptools\build_meta.py", line 481, in get_requires_for_build_editable return self.get_requires_for_build_wheel(config_settings) File "C:\Users\jeffg\AppData\Local\Temp\pip-build-env-iyul_9eb\overlay\Lib\site-packages\setuptools\build_meta.py", line 333, in get_requires_for_build_wheel return self._get_build_requires(config_settings, requirements=[]) File "C:\Users\jeffg\AppData\Local\Temp\pip-build-env-iyul_9eb\overlay\Lib\site-packages\setuptools\build_meta.py", line 301, in _get_build_requires self.run_setup() File "C:\Users\jeffg\AppData\Local\Temp\pip-build-env-iyul_9eb\overlay\Lib\site-packages\setuptools\build_meta.py", line 520, in run_setup super().run_setup(setup_script=setup_script) File "C:\Users\jeffg\AppData\Local\Temp\pip-build-env-iyul_9eb\overlay\Lib\site-packages\setuptools\build_meta.py", line 317, in run_setup exec(code, locals()) File "<string>", line 10, in <module> ModuleNotFoundError: No module named 'pip' [end of output] note: This error originates from a subprocess, and is likely not a problem with pip. ERROR: Failed to build 'file:///D:/code/yoloe/third_party/lvis-api' when getting requirements to build editable

and yet, when I run the command pip list :

Package Version ---------- ------- packaging 25.0 pip 26.0.1 setuptools 80.10.2 wheel 0.46.3

Here it is. This has caused me to suspect that the problem isn't with pip but rather with system configurations. Here's my .condarc :

channels: - defaults show_channel_urls: true envs_dirs: - D:\ProgramData\anaconda3\envs pkgs_dirs: - D:\ProgramData\anaconda3\pkgs

This is what I get when I run conda info:

And I have properly added the following to my PATH:

D:\ProgramData\anaconda3 D:\ProgramData\anaconda3\Scripts D:\ProgramData\anaconda3\Library\bin D:\ProgramData\anaconda3\Library\mingw-w64\bin

It seems to me that I've done nothing wrong(that is, I have been following the instructions I found online, chances are that some of those are wrong), and I've tried all existing solutions like python ensurepip, but to no avail. Could someone please help me fix this?
