Change executable path of a program

While I was trying to install mupdf backend for Zathura, I accidentally did pip install zathura (in user mode) as Meson build kept complaining about a missing dependency, and now the executable path for zathura is now ~/.local/bin/zathura instead of /usr/bin/zathura. I tried uninstalling the wrong program with pip (as well as uninstall/reinstall the correct zathura package), but it still complains about the wrong executable path. It's possible to set it back using an alias (e.g. alias zathura="/usr/bin/zathura"), but I'd rather not do that unless that's exactly how it works behind the scenes. Is there another way to change the executable path?
