prettier is not running on precommit. This worked with the same configuration in other projects, so I'm baffled why it's not working this time.

This is the relevant section of my package.json file:

"scripts": {
    "precommit": "lint-staged"
  },
"lint-staged": {
  "*.{js,json,css,scss,html,md}": [
    "prettier --write",
    "git add"
  ]
},

Edit. Here are the relevant devDependencies:

"devDependencies": {
  "husky": "^0.14.3",
  "lint-staged": "^7.0.4",
  "prettier": "1.12.0"
},

The problem for me was I ran "npx mrm lint-staged" like the official website says but it only set the husky and lint-staged configurations in package.json. It does not add then as dependency or installed them.

The solution for me was:

  1. npm i -D husky lint-staged

  2. npx mrm lint-staged
