这个“pyvenv.cfg”文件在哪里？

Question

I give a quotation of site module documentation below and i am not aware where “pyvenv.cfg” file actually exists.Does it just exist in a directory one level higher than sys/executable 's ?

If a file named “pyvenv.cfg” exists one directory above sys.executable, sys.prefix and sys.exec_prefix are set to that directory and it is also checked for site-packages (sys.base_prefix and sys.base_exec_prefix will always be the “real” prefixes of the Python installation). If “pyvenv.cfg” (a bootstrap configuration file) contains the key “include-system-site-packages” set to anything other than “false” (case-insensitive), the system-level prefixes will still also be searched for site-packages; otherwise they won't.

Answer 1

It doesn't exist unless it is created.

If ...

And if it is created, it should be in the same directory as the executable or one directory above as per PEP 405 .
