Installing TA-lib

The pandas-ta Python package extends Pandas to provide easy support for technical analysis indicators. However, during my initial attempt to install the package, I encountered an issue with installing the required TA-lib.

Here is the error message I received:

python3 -m pip install TA-lib

Upon investigation, I discovered that the TA-lib Python package is actually a wrapper around a C library. Therefore, it was necessary to install the C library separately. I resolved this by executing the following command:

brew install ta-lib

After installing the C library, I attempted to install the Python package again, and this time it was successful:

python3 -m pip install TA-Lib

I hope this information helps you with your installation process.

Please let me know if you have any further questions or concerns.
