如何在Mac上为Python 3.6.4安装pip？现有方法均失效求助

Hey there, let's sort out this pip install mess for your Python 3.6.4 on Mac—your issues sound like a mix of using the wrong environment and incorrect commands, so let's break it down step by step.

First, let's fix the common mistakes you ran into: #

• Why get-pip.py threw a syntax error: You probably tried running the script inside the Python interactive shell (the one with >>> prompts) instead of from the terminal. The get syntax error happens because the shell thinks you're writing Python code, not executing a standalone script.
• Why apt and easy_install failed: apt is a Linux package manager—Mac doesn't use it at all! And when you saw commands with $, that's just the terminal's prompt symbol, not part of the actual command. You should always omit the $ when typing commands into the terminal.

Now, let's try the reliable methods to install pip for Python 3.6.4: #

Method 1: Use Python's built-in ensurepip (Most Recommended)

Python 3.4+ comes with a built-in tool to install pip directly. Open your terminal (not the Python shell) and run this command:

python3.6 -m ensurepip --upgrade

This tells Python 3.6 specifically to use its ensurepip module to install or update pip. If you hit a permission error, add --user to install it for your user account only (avoids needing sudo):

python3.6 -m ensurepip --upgrade --user

Method 2: Correctly run get-pip.py

If you still want to use the get-pip.py script, follow these steps:

1. Make sure you've downloaded get-pip.py to an easy-to-access folder (like your Desktop).
2. Open Terminal and navigate to that folder:

   cd ~/Desktop
   

3. Run the script using your Python 3.6 executable:

   python3.6 get-pip.py
   

Again, add --user if you encounter permission issues:

python3.6 get-pip.py --user

Method 3: Use easy_install (Only if the above methods fail)

Mac's default easy_install is tied to Python 2, so you need to target Python 3.6 specifically. First, check if easy_install-3.6 is available:

easy_install-3.6 pip

If that command isn't found, call it via Python 3.6's module system:

python3.6 -m easy_install pip

Verify the installation worked #

After trying any of these methods, confirm pip is installed for Python 3.6 by running:

pip3.6 --version

This should display the pip version linked to your Python 3.6.4 installation.
