`make html` fail when generate document in local computer

Conduct the command:

make html

but the following error occurs:

/bin/sh: sphinx-build: command not found
make: *** [html] Error 127

But, actually, sphinx has been installed.

https://stackoverflow.com/questions/37757151/the-sphinx-build-command-was-not-found provide an effective approach to address this. In summary, conduct below commands:

brew install sphinx-doc
export PATH="/usr/local/opt/sphinx-doc/bin:$PATH"
# export PATH="/opt/homebrew/opt/sphinx-doc/bin:$PATH" (for mac M1 ARM computers)
