Doom-emacs: doctor report issues

[ModarYaghi]

Hello, I am new in emacs world and trying to follow emacs experts' instructions as far as I can. After making some uncomment to some of init.el available choices and did bin/doom/install, I ran bin/doom doctor and I received this message! Any idea how to fix these issues? Please.

You should run doom sync whenever you modify init.el (and packages.el). Hopefully that fixes the errors.

gls, cmake, markdown compilers, pipenv, nosetests, spellcheck, stylelint and js-beautify are all external programs that certain packages in Doom need to function. However, Doom will function fine without them, so if you don't know what they do or don't need them, you can ignore them.

Otherwise, you'll need to install them through your OS's package manager (homebrew, in your case), or your language's package manager (pip or npm). e.g.

brew install coreutils cmake sbcl markdown shellcheck node python3
pip install pipenv nosetests
npm i -g stylelint js-beautify

Thank you very much hlissner, your answer did solve the issue.
