glenn, help me install ta-lib!

I'm using the command "pip install TA-lib --user". It shows some lines indicating that it's being installed, but then it stops at one line. It keeps waiting for hours and eventually throws an error. Below, I'm sharing the code lines:

09:38 ~ $ pip install TA-lib --user Looking in links: /usr/share/pip-wheels Collecting TA-lib Using cached ta_lib-0.6.3.tar.gz (376 kB) Installing build dependencies ... done Getting requirements to build wheel ... done Installing backend dependencies ... done Preparing metadata (pyproject.toml) ... done Requirement already satisfied: setuptools in /usr/local/lib/python3.10/site-packages (from TA-lib) (60.2.0) Requirement already satisfied: numpy in /usr/local/lib/python3.10/site-packages (from TA-lib) (1.21.6) Building wheels for collected packages: TA-lib Building wheel for TA-lib (pyproject.toml) ... |

What command did you run and what error message do you see?

You need to use the ta-lib python package that matches the library that we have install. So, if you do

pip install --user 'ta-lib<0.5'

it will install correctly.
