MSYS2: pip is not in path after installation (command not found)

I installed pip on MSYS2 using the following command in the MSYS2 shell: pacman -S mingw-w64-x86_64-python-pip (web page for the package: https://packages.msys2.org/package/mingw-w64-x86_64-python-pip)

After installing, when I try to run pip in the MSYS2 shell I get: bash: pip: command not found

For some reason, it didn't install pip anywhere in the MSYS2 system path. There is no file called "pip" in C:\msys64\usr\bin. The installation did, however, add a file called "pip" in C:\msys64\mingw64\bin. This directory is not part of the default path that MSYS2 uses.

Am I supposed to add C:\msys64\mingw64\bin to my MSYS2 PATH? More importantly, why did it install pip to a directory that isn't in PATH? Is there a reason for this annoyance?
