Its asking me to get Microsoft C++ Build Tools but do i need a c++ complier for Locust version 2.15.1? I previously was able to install locust version 2.14.2 and I never got that error and I didn't have to install Microsoft C++ Build Tools. Just wondering if its needed for this newer locust version? The python version I'm currently using is 3.10.9.

I'm expecting this to install without failing.

  • Seems that the error comes from a different package (dependency). https://stackoverflow.com/a/75307579/4788546, https://stackoverflow.com/a/73805010/4788546, https://stackoverflow.com/a/75150938/4788546, https://stackoverflow.com/a/57883242/4788546 might provide some details (although won't contain a fix for your specific problem). – CristiFati Apr 19 '23 at 11:05

I think the problem is that there is no binary version of the latest release of greenlet for your particular OS version.

If you done want to install build tools, try pip install --prefer-binary locust
