Fatal Errors during installation (after preparing isolated conda environment for pip installation) [BUG]

[richlysakowski]

Describe the bug

Installing the package using the recommended command "pip install qtpylib --upgrade --no-cache-dir" gives a Fatal error and stops with the final message: "ERROR: No matching distribution found for qtpylib" after re-trying every available of the package that exists on pypi.org.

Steps to reproduce the behavior:

1. create a new conda virtual environment and activate the new environment:
   conda create -n qtpylib python=3.8
   ```activate qtpylib`

2. add all available conda packages in the requirements.txt file
   conda install flask pandas pytz requests python-dateutil pymysql pyzmq beautifulsoup4 twilio

3. try to install Interactive Brokers packages using conda:
   conda install ibpy2` (FAILED, but used pip later.)
conda install -c conda-forge ibpy2
   (FAILED, with PackagesNotFoundError: The following packages are not available from current channels:

• ibpy2

4. install workaround for pip-anaconda known interoperability bug recommended by Ran Aroussi
   (SUCCEEDED with a WARNING:

5. install qtpylib using suggested pip install command:

### This resulted in many failed attempts to install the qtpylib package, all the way from the newest to the oldest version available.

Getting a similar fatal error when trying to install the library. Shame, it seems very capable, is Ran still active on this repo?

Looks like this reop is not under maintainance now.
