Installing pygame with homebrew

问题:

I am trying to install pygame for Python3 using Homebrew. (I have both Python 2 and Python 3 on my machine.)

I used this Reddit page, which says:

brew tap Homebrew/python
brew update
brew install pygame

This works perfect and installs pygame successfully on my Python 2.7. However, Python 3 still does not have pygame.

I also found that I can do it using pip3. However, I am looking for a way to install pygame for Python 3 using Homebrew.

Adding --with-python3 is the key here. You can install via brew install --with-python3.

In general brew info <package-name> will give you additional information. In this case brew info pygame prints:

Homebrew might be the tool you need to get this done. But first;

• Do you have homebrew installed? To check, in your terminal, type in brew. A list of commands should follow. If not install homebrew, here https://gorails.com/setup/osx/10.11-el-capitan, and follow the homebrew instructions section
• Once homebrew is setup, run 'brew update'
• Then run 'brew install pygame'. It might prompt you install 'homebrew/python/pygame' instead, copy that command and run it
