This is very unlikely. If there were issues in this area, we would be
seeing many more bug reports. More likely is that the PATH variable
doesn't contain what you think it does. First thing I would do is try
running the following source block
and verify the direnv bin directory is actually in your path.
Emacs will inherit the path from the shell running when emacs is
started. Changes made in your shell after Emacs has started will have no
effect on the PATH variable for emacs.
You mentioned at one point your running exwm. If you are not running
exwm in a login shell and your not sourcing your ~/.profile prior to
starting Emacs/exwm (assuming the direnv settings and path are setup
there), then the path variable is not going to have the direnv bin
directory. Either you need to ensure the appropriate direnv bin
directory is in your path before starting exwm or you need to add a
configuration step (e.g. possibly a hook function) which will add the
direnv bin directory using setenv.
