error while installing pyforms on macos

[quanhinh9]

Hi,

I install pyforms on macos: pip3 install pyforms

And get error: ERROR: Could not find a version that satisfies the requirement opencv-python==3.4.5.20 (from pyforms-terminal->pyforms) (from versions: 3.4.8.29, 3.4.9.31, 3.4.9.33, 4.1.2.30, 4.2.0.32, 4.2.0.34)
ERROR: No matching distribution found for opencv-python==3.4.5.20 (from pyforms-terminal->pyforms)

How to fix it?

If this is on python 3.8 it could be related to #102
