Environment

• OS: macOS on M1
• Python version: 3.8.9

I have the same problem. OS: macOS on M1 Python version: 3.11

I dont think that is the same problem? Your logs look look like it fails building greenlet, not cffi? There are no pre-built wheels for python 3.11, and it is not really supported yet.

Either way: Please try installing the respective packages directly and (assuming that fails) file tickets for the respective packages instead.

Thank you for your reply. I have just solved it.

Use Python 3.10

I just tried installing locust on my M1 and it installed without any problem.
