You can download the corresponding version of pysvn from the download page:

, then double-click to open the installation, no need to use pip to install.
It should be noted that if the installation prompts that chdir fails and /Library/Frameworks/Python.frameworkthe path does not exist, it may be that there is a problem with the python installation path. Reinstalling python can solve this problem.
In addition, an excerpt from a passage in the official python documentation :
Apple-provided versions of Python are installed in /System/Library/Frameworks/Python.framework and /usr/bin/python, respectively. You should never modify or delete these contents because they are controlled by Apple and used by Apple or third-party software. Keep in mind that if you choose to install a newer Python version from python.org, you will have two different but useful versions of Python installed on your computer, so it's important that your paths and usage match what you want to do .
