Environment

• OS: macOS on M1
• Python version: 3.8.9

I dont have an M1 to test with. Can you reproduce it by just installing just cffi (or gevent) directly? In that case, maybe file an issue with them?

[brendandebeasi]

Have you tried running it within Docker? I haven't had any issues on my 2021 16" M1 MBP

[Hritik14]

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

[mnvum]

I have the same problem.

OS: macOS on M1
Python version: 3.11

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

Closing this issue, I used npm package autocannon instead.
Locust might be better than autocannon but I just wanted to test one http path so it worked fine.
