Error installing pygame on MacOS: 'longintrepr.h' file not found-CodePudding

I am trying to install the pygame library on my Mac running macOS 11.0 Big Sur, but I keep getting errors related to missing files, such as 'longintrepr.h' and 'pkg-config'. I have tried installing the library using pip3 and a virtual environment, but I am still encountering the same issues. I am looking for a solution to successfully install the pygame library on my Mac.

 #include "longintrepr.h"
                 ^~~~~~~~~~~~~~~

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.

I have the newest version of python3 installed.

I tried to install pygame using pip on my MacOS machine but I encountered an error "src_c/_sdl2/sdl2.c:211:12: fatal error: 'longintrepr.h' file not found" during the installation process. I also tried creating a virtual environment and installing pygame there but still encountered the same error. I was expecting the installation process to complete successfully without any errors.

CodePudding user response：

On the official pygame repo, there's a huge thread regarding installation of pygame in python 3.11 (latest version) not working properly yet.

Try installing pip install pygame --pre for now, which is going to install a developmental release of the newest, prereleased pygame version, or if you want stability using an older version of python also works.
