Ishan Shah, Rekhit Pachanekar and Gaurav Singh demonstrate how to install Ta-Lib across platforms using Anaconda prompt in Part I, and showcase how to install it on Windows PC in Part II.

Install Ta-Lib on MacOS

In comparison to the windows installation, Python Ta-Lib installation is relatively straightforward and easy on the MacOS. But before we talk about the installation of Ta-Lib, we have to make sure the python environment is installed as well.

You can install Anaconda from here or download Python from here.

In our opinion, it is generally a good idea to install Anaconda as it helps build an environment for your python code to be executed seamlessly.

Note: During the Anaconda installation, you will be asked to install either Python 2.7 or 3.7. Since the support for Python 2.7 ended on January 1, 2020, it would be advisable to select the 3.7 version. For a seamless installation, choose the graphical installer.

mac_python_version

You will then be greeted with the following dialog box.

Select “Continue” tab and choose the appropriate install destination and you will finish installation in a short time.

All right, now we move on to the main event, i.e. Python Ta-lib installation. Ok, there is one small step you need to do before the main install.

Check if you can use the ‘brew’ command. For this tutorial on how to install Ta-Lib, let us assume that the ‘brew’ command throws an error. To rectify this, we install the necessary package by using the following line of code in the MacOS shell:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

If it is successful, you will see the following messages:

homebrew_install

Of course, you will get a prompt which asks you to press “Return” to continue the installation or any other key to cancel the installation. If you are curious about the ‘brew’ command, you can always visit this website to know more.

Great! Now that the brew command is installed, use the following code to install the Ta-Lib operating system dependencies:

brew install ta-lib

You will see the following screen

Now, we use the familiar command i.e. “pip” to install Ta-Lib on our MacOS. The command is as follows:

pip install ta-lib

You see the following files being installed on your system.

Great! We have been successful in our quest to install Ta-Lib on MacOS.

But how do we check if it is correctly installed on the system? Simple, we use the following commands.

First, we call the python language by simply writing “python” in the terminal. We then use the following command to import the Ta-Lib library.

import talib

If there is no error, then we should be able to see the following screen

In the next installments, the authors will demonstrate how to install Ta-Lib on Install Ta-Lib on Linux.
