Installation Failure in Clean Environment

I am getting the following error when trying to install my package in CI when it goes to install fxpmath:

 Collecting fxpmath>=0.3.5

Due to the way that it is currently retrieving its version information, numpy must be installed prior to installing fxpmath. pip does not have a proper dependency resolver so in my situation fxpmath is installed before numpy, leading the numpy import in “objects.py” to fail during the installation.

Thanks for explanation. Sorry, but I answered without seeing merge request. The solution seems good! Thank you. I’m going to accept the merge request and update package in pip/conda soon. Don’t forget close the issue if you test and it’s ok for you.

No worries!

I tested locally & was able to install the package with no problems. I’ll go ahead & close out the issue.

Thanks for this awesome package and your quick response!
