Mac版Enthought Canopy能否切换为32位Python以适配pygame？

Hey there! Let's get your Enthought Canopy running in 32-bit mode so you can use pygame without issues. Since you're new to this, I'll walk you through the simplest methods step by step:

Method 1: Launch Canopy in 32-bit Mode Temporarily #

This is perfect if you only need the 32-bit environment occasionally:

• First, close all open Canopy windows (editor, terminal, package manager—everything).
• Open your Mac's Terminal (find it in Launchpad > Other).
• Run this command to start Canopy in 32-bit mode:

  arch -i386 /Applications/Canopy.app/Contents/MacOS/Canopy
  

• Once it launches, your Canopy environment will be running 32-bit Python, and you should be able to install and use pygame successfully.

Method 2: Set Canopy to Default to 32-bit Mode #

If you want 32-bit to be the default every time you open Canopy:

1. Close all Canopy windows first.
2. Find Canopy.app in your /Applications folder. Right-click it and select Show Package Contents.
3. Navigate to the Contents folder and locate the Info.plist file.
4. Open it with a text editor (like TextEdit—if you hit a permission error, use sudo nano /Applications/Canopy.app/Contents/Info.plist in Terminal instead).
5. Look for the LSArchitecturePriority key. If it exists, change the value from x86_64 to i386. If it doesn't exist, add this block to the file:

   <key>LSArchitecturePriority</key>
   <array>
       <string>i386</string>
   </array>
   

6. Save the file and restart Canopy. It will now launch in 32-bit mode by default.

Important Notes #

• Keep in mind that switching to 32-bit means any 64-bit packages you previously installed might stop working. If you need to go back to 64-bit later, just reverse the steps above, or run arch -x86_64 /Applications/Canopy.app/Contents/MacOS/Canopy in Terminal.
• Make sure you install a 32-bit compatible version of pygame. You can use Canopy's built-in Package Manager to search for pygame and pick the version that matches your 32-bit environment.
