Unable to build lr-pcsx-rearmed

Help!
Pi Model: 3B+
File Path: /home/pi/RetroPie-Setup/tmp/build/lr-pcsx-rearmed/pcsx_rearmed_libretro.so

I am trying to install the lr-pcsx-rearmed emulator to fix another problem preventing me from updating my RetroPie Setup Script. Whenever I try to install the lr-pcsx-rearmed emulator from source it gives me the message that the pcsx_rearmed_libretro.so file is missing. But it is not missing, I downloaded it and put it in the correct folder and rebooted several times. Very frustrating. What can I do to have a clean installation from Source to fix my emulator without completely uninstalling it

Update the RetroPie-Setup script first and then re-try the source installation.

@mitu it won't let me update the retropie script... It gives me this error message.

@90sgamer This means the files was modified by you and RetroPie-Setup doesn't know how to update it. Revert the modifications you did on the file and re-try the update.

@mitu I am unsure or unaware of any modifications I made. What should I do?

@mitu The file had the wrong file extension. I got it to update now!
