Python -m site -help command cannot find the site.py path? How to modify the default path of the pip installation package?

Python site module path search problem and pip installation path modification

Many Python developers use the python -m site -help command to view the path of the site.py file for configuration modifications when trying to change the default path of the pip installation package. However, some users found that the command outputs frozen [--user-base] [--user-site] information, rather than the expected site.py path. This article analyzes this issue.

Problem: The user hopes to find the site.py path through python -m site -help to modify the pip default installation path, but the actual output is frozen [--user-base] [--user-site] and there is no path information. This means that site module may be in a frozen state (frozen) and its configuration information is not read directly from site.py

Another similar problem: Even if --user-base and python -m site --user-site parameters in site module are modified, the results are still unchanged and no errors are reported. This means that directly modifying the site.py file is invalid, because the configuration of site module may not be stored in site.py , but is managed through other mechanisms. This may be due to differences in Python installation or version.

frozen state indicates that the configuration information of site module may have been compiled into the Python interpreter rather than exist in a standalone file form. Therefore, modifying site.py directly is invalid. To solve this problem, we need to further explore the installation path of the Python interpreter and how it configures the site module. You may need to modify the pip installation path through other methods, such as setting environment variables.
