Modifying $PATH in Make on macOS

Makefile

# You can, in fact reference node_modules without the prefix by prepending node_modules to your $PATH with this line:
export PATH := ./node_modules/.bin:$(PATH)

# But for some reason, on macOS, Make doesn’t recognize the $PATH when it’s the start of a command.
# So this rule doesn’t work. It treats `prettier` as a file/directory:
format: node_modules
	@prettier --write .

# But this rule does:
format: node_modules
	@true && prettier --write .

# Erring on the side of simplicity and clarity, it's probably best to just include the full prefix.

Oo interesting. This is the top of the Makefile I ran:

SHELL=bash
export REACT_APP_GIT_HASH := $(shell git rev-parse HEAD)
export PATH := ./node_modules/.bin:$(PATH)

I'm using stock make, but a bit older

GNU Make 3.81
