Cannot find ta-lib library, installation may fail. (and does)

[ParityError]

When I try to install on macOS 10.14.6 with Python 3.7 installed I get an error that TA-Lib cannot be found:

# first, make sure that the PyPi version is not installed
pip uninstall jesse

# now install Jesse from the repository
git clone https://github.com/jesse-ai/jesse.git
cd jesse
pip install -e .

Error output:

[ParityError]

The error is caused because my Python is installed with MacPorts.

The solution is to:

$ sudo port install ta-lib

Did you follow the steps in the docs?
https://docs.jesse.trade/docs/getting-started/environment-setup.html#macos

[ParityError]

@cryptocoinserver, It would be helpful to include instructions in the document you linked for people using MacPorts as not everyone uses Homebrew on macOS.
