Why isn't the kernel module Makefile recognizing any files in the directory?

Question

I'm just starting to work on kernel module programming and I'm having a hard time getting the makefile to properly compile the c files. I'm using Manjaro 5.4

When I execute make in the same directory as the code and this Makefile:

obj-m += hello1.o

PATH = /usr/lib/modules/$(shell uname -r)/build

all:
    $(MAKE) -C $(PATH) M=$(PWD) modules

clean:
    $(MAKE) -C $(PATH) M=$(PWD) clean

I get the output of

make -C /usr/lib/modules/5.4.67-1-MANJARO/build M=/home/aidan/Documents/kernelProgramming/hw2 modules
make: make: No such file or directory
make: *** [Makefile:7: all] Error 127

I've checked I have all the correct headers installed

And the path /usr/lib/modules/5.4.67-1-MANJARO/build looks like this:

$ ls
arch   crypto   include  kernel    mm              samples   sound  virt
block  drivers  init     lib       Module.symvers  scripts   tools
certs  fs       Kconfig  Makefile  net             security  usr

I'm quite stumped and I cannot find out the reason why it gives me that error.
