rebuild-node-sass

Rebuilds node-sass but only if needed

Use

npm install --save-dev rebuild-node-sass node-sass

Then before build (when node-sass is probably used), call rebuild-node-sass
to make sure it is ready

{
  "scripts": {
    "prebuild": "rebuild-node-sass",
    "build": "..."
  }
}

Testing

To execute in a different environment, for example when working on Mac, we
can install Mac Sass binary npm install and then switch to Docker

docker run -v $PWD:/src -w /src -it node /bin/bash

which produces the following output (abridged)

root@0d0cd593e320:/src# ./rebuild.sh
npm info it worked if it ends with ok
npm info using npm@5.0.0
npm info using node@v8.0.0
npm info ok

      throw new Error(errors.missingBinary());
