pip install decord returns error on macOS

[shannelu]

1. When I used pip install decord, it returned:

ERROR: Could not find a version that satisfies the requirement decord (from versions: none) ERROR: No matching distribution found for decord

2. When I tried to install from source, I am getting the same error as: https://github.com/dmlc/decord/issues/105 on Mac OS

I'm on macOS: I ran into a similar issue to this, and was able to resolve it by running: brew install ffmpeg -devel and running the rest of the instructions.

A follow-up question. Any suggestions why pip3 install decord couldn't work?

Had the same issue: macos == 11.6.5 and python == 3.9

Solution: Installed a new environment with python 3.7 and pip install decord worked like charm.

Do not using decord,

This is a very last lib I saw it claimed surpress opencv but didn't support macOS and python3.9+
