Mac 10.13.4系统下无法搭配MuPDF安装PyMuPDF的问题求助

Hey there, fellow Python newbie! Let's break down this PyMuPDF installation clearly—since you're on a beta version of macOS 10.13.4, we need to skip unnecessary steps and avoid common pitfalls.

First off: you don't need to manually build MuPDF from source! That's the key point you were unsure about. The brew install mupdf-tools command you ran already installed a pre-compiled, working version of MuPDF (and its tools) on your system. Homebrew handles all the messy compilation details for you, so you can totally skip following the official MuPDF build docs.

Here's what to do next to finish installing PyMuPDF:

• Keep your ARCHFLAGS setting intact
  The export ARCHFLAGS='-arch x86_64' command you ran is crucial for your macOS version, since it fixes potential architecture mismatches. Just note that this setting only applies to your current terminal window. If you open a new terminal later, you'll need to re-run it, or add it to your shell config file (~/.bash_profile for Bash, ~/.zshrc for Zsh) to make it permanent.

• Install PyMuPDF via pip
  Now you can jump straight to installing the Python package. Use the pip command matching your Python version to avoid confusion:

  • For Python 3 (recommended for new projects): pip3 install PyMuPDF
  • If you hit permission errors (common with system Python), add the --user flag to install it in your user directory (no sudo needed): pip3 install --user PyMuPDF

• Clean up any leftover MuPDF source files
  If you started running make on the MuPDF source you downloaded, you can just delete that entire folder—Homebrew's installed version is all you need, and those source files won't affect your PyMuPDF installation.

• Verify the installation worked
  Open a Python terminal by typing python3 in your terminal, then run these lines:

  import fitz  # PyMuPDF uses the 'fitz' module name—don't let that confuse you!
  doc = fitz.open()
  doc.insert_page(0, text="Hello, PyMuPDF!")
  doc.save("test_pymupdf.pdf")
  doc.close()
  

  If no errors pop up, check your current folder for the test_pymupdf.pdf file—if it exists and opens correctly, you're all set!
