yarn cannot build node-sass with node 12.1.0

Question

I am trying to install my packages with yarn install

I have node 12.1.0 installed, and as I understand, node-sass needs to be at least version 4.12+ to work with node 12

my package.json file is as so:

{
  "name": "redacted",
  "private": true,
  "dependencies": {
    "@rails/webpacker": "3.5",
    "babel-preset-react": "^6.24.1",
    "bootstrap": "^4.1.2",
    "font-awesome": "^4.7.0",
    "js-md5": "^0.7.3",
    "moment": "^2.22.2",
    "prop-types": "^15.6.2",
    "qrcode.react": "^0.8.0",
    "react": "^16.4.1",
    "react-big-calendar": "^0.19.2",
    "react-dom": "^16.4.1",
    "react-loading": "^2.0.3",
    "react-router": "^4.3.1",
    "react-router-dom": "^4.3.1",
    "react-transition-group": "^2.5.0",
    "urijs": "^1.19.1"
  },
  "devDependencies": {
    "webpack-dev-server": "2.11.2"
  }
}

The (truncated) error I get is:

../fsevents.cc:85:58: error: expected ';' after top level declarator

                                                         ^

I have tried installing just node-sass alone with yarn add node-sass but it still fails with the same sort of error.

How can I get get past this?

Answer 1

I managed to solve this by deleting my lockfile and running yarn install again.
