I am trying to install TA-Lib and everything I try does not work. I do not know what package wheel is and why the error references numpy but I am hoping someone can help me.
What I am using:
PS C:\Users\ebben> pip install TA-Lib
Collecting TA-Lib
Using cached TA-Lib-0.4.19.tar.gz (267 kB)
Requirement already satisfied: numpy in c:\python39\lib\site-packages (from TA-Lib) (1.20.2)
Using legacy 'setup.py install' for TA-Lib, since package 'wheel' is not installed.
Installing collected packages: TA-Lib
Running setup.py install for TA-Lib ... error

TA-Lib is a C-library. You're trying to install a python wrapper for it and it can't find C library during installation. Wrapper prints:
setup.py:71: UserWarning: Cannot find ta-lib library, installation may fail.
So, firstly, install the C library binary, then install python wrapper. Check out Dependencies section at https://mrjbq7.github.io/ta-lib/install.html
