Unable to install TA-lib on pythonanywhere

Hi guys,

I have been working on a project that requires the talib module but it cannot be installed on the server. So far I have tried,

  • easy_install --user TA-lib
  • pip install TA-lib --allow-external TA-lib --alow-unverified TA-lib

but none seems to work.

Does anyone has the same problem?

Have you tried the second command (the pip) with the --user flag? What error did it give you?

i am having the same problem using pip or easy_install

Looks like we need to install the ta-lib library. We'll try to get that into the next update in a few weeks.

Thanks, Glenn. Looking forward to the update.

...and it's installed now. Let us know if how it looks to you!

Thank you, thank you, thank you! I'll try :3

pip install TA-lib --user worked for me

Thanks for confirming that!

What am I missing ? Running default python (3.9) pip install TA-lib --user (Seemed to go ok?) But in a .py script testing it:

import talib
