How to resolve two perl version in MacOS?

I installed perl with brew then I found that when I type perl -v it says 5.18.1 but when I type in which perl it says /usr/local/bin/perl and if I type /usr/local/bin/perl -v it says 5.28.1 which I believe is the brew version. The problem now is that I can run some perl script in terminal without problem (5.18.1) but run in python by calling subprocess, it will call 5.28.1 version which causes the script to fail. Any idea how I can use 5.18.1 inside the subprocess?

Then see this question and this question for an explanation of hashed commands. Perhaps you edited your PATH after your shell had already made a hash entry for the perl command.

You can delete the hash entry with

hash -d perl

And then perl should resolve to the same location returned by which perl.

To remove all hashed commands, say, after you update the PATH variable, the command is

hash -r
