Installation from pipy is failing.

[Pondiniii]

Hi,
I tried to install DXcam using command provided in the description: pip install -i https://test.pypi.org/simple/ dxcambut it throws this error:

PS C:\Users\Administrator\PycharmProjects\dxcam> pip install -i https://test.pypi.org/simple/ dxcam

ERROR: Cannot install dxcam==0.0.2 and dxcam==0.0.3 because these package versions have conflicting dependencies.

The conflict is caused by:
    dxcam 0.0.3 depends on comtypes
    dxcam 0.0.2 depends on comtypes

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/topics/dependency-resolution/#dealing-with-dependency-conflicts

To fix it, I tried to install dependencies manually first using this command:
pip install opencv-python numpy comtypes
it returned:
Successfully installed comtypes-1.1.11 numpy-1.21.6 opencv-python-4.5.5.64

Then I typed:
pip install -i https://test.pypi.org/simple/ dxcam==0.0.3

Output of following command says it installed successfully, but when I try to run the following code:

import dxcam
camera = dxcam.create()
camera.grab()

I get this:

C:\Users\Administrator\PycharmProjects\dxcam\venv\Scripts\python.exe C:/Users/Administrator/PycharmProjects/dxcam/test.py

I Tried to git-clone folder (dxcam) into venv/lib/dxcam/ but it didn't help. Now I get:

ImportError: cannot import name 'DXCamera' from 'dxcam.dxcam' (C:\Users\Administrator\PycharmProjects\dxcam\venv\lib\site-packages\dxcam\dxcam\__init__.py)

Process finished with exit code 1

Btw. I tried it on Arch Linux (py3.9) and Windows 10 (using py3.7 and 3.9).

Workaround:
git clone https://github.com/ra1nty/DXcam
cd DXcam
pip install opencv-python numpy comtypes
cp /benchmarks/dxcam_max_fps.py dxcam_max_fps.py
python dxcam_max_fps.py

Hi Pondiniii,

Thanks for trying out my library. Apologize -- I made a stupid mistake when creating setup.cfg.
Please try installation again from test pypi:

pip install --index-url https://test.pypi.org/simple/ --extra-index-url https://pypi.org/simple dxcam

The issue should be fixed now.

Thanks.
