mmm-mode is available on Melpa.
Yet both
`M-x` `list-packages` `C-s` `mmm-mode`
and
`M-x` `package-install` `mmm-mode`
suggest that it's not.
How do I install mmm-mode (through MELPA)?

You have to add the melpa repository to your package archives.
In your .emacs init file you have to add the following lines:
Then, when listing the available packages, you will find mmm-mode:

I had just one (stable.melpa.org/packages). Adding the two you suggest does not help. I'm using Emacs 25 (and so the third you suggest does not apply).– CalafCommented Nov 7, 2017 at 16:49

Hmm, that seems strange. Those are the only repositories I have. If you see in the second image, my mmm-mode comes from MELPA, so adding the source melpa.org/packages should allow you to get it. Make sure to add the package and then run
M-x package-list-packages. Which emacs version are you using?– MartínCommented Nov 7, 2017 at 19:04 -
If I type
/Applications/Emacs.app/Contents/MacOS/Emacs-x86_64-10_9in the Terminal, with a.emacscontaining (require 'package) (add-to-list 'package-archives '("MELPA Stable" . "stable.melpa.org/packages/") t) (add-to-list 'package-archives '("MELPA" . "melpa.org/packages/") t) (add-to-list 'package-archives '("org" . "orgmode.org/elpa/") t) (package-initialize) , and then callpackage-list-packages, Emacs crashes. I'm running GNU Emacs 25.3.1 on High Sierra. I guess it's more serious than just a lack of mmm-mode.– CalafCommented Nov 8, 2017 at 2:12 -
It's not specific to 25.3.1. Emacs 25.2.1 also crashes in that exact setup. Not sure if it happens on Sierra or El Capitan.– CalafCommented Nov 8, 2017 at 2:15

The
.emacsinit file should be in your home directory, for instance, in my case it is in/Users/martin/. That is the file that gets loaded when emacs starts. The other one I think it is a system example file. You can verify which init file gets loaded withC-h v user-init-file [RET]– MartínCommented Nov 8, 2017 at 13:13
mmm-modeis not in melpa anymore, it's actually in ELPA now.mmm-modeisn't inmelpaanymore), and the description provided in comments suggests the actual problem is unrelated tommm-modeandmelpa.
