package.json is not node-pre-gyp ready, but what do the properties mean?

Question

I want to deploy an app to heroku. A while ago it was working, but when I tried to push, now it gives me "Push rejected".

I tried to run node-pre-gyp install and it tells me that my package.json is not node-pre-gyp ready, telling me that:

package.json must declare these properties:

main

version

binary.module_name

binary.module_path

binary.host

It seems like this is the problem, however, I'm quite new to web developing (this is my first project) and I have no idea what these properties mean so I don't know how to add them in my package.json.

heroku login
git add .
git commit -m "test"
git push heroku master

This is how I usually deploy the code.

{
  "name": "myproject",
  "private": true,
  "engines": {
    "node": "8.10.0"
  },
  "scripts": {
    "start": "meteor run",
    "test": "meteor test --once --driver-package meteortesting:mocha",
    "test-app": "TEST_WATCH=1 meteor test --full-app --driver-package meteortesting:mocha",
    "visualize": "meteor --production --extra-packages bundle-visualizer"
  },
  "dependencies": {
    "@babel/runtime": "^7.6.0",
    "bcrypt": "^3.0.0",
    "bcryptjs": "^2.4.3",
    "meteor-node-stubs": "^0.4.1",
    "node-pre-gyp": "0.13.0"
  },
  "meteor": {
    "mainModule": {
      "client": "client/main.js",
      "server": "server/main.js"
    },
    "testModule": "tests/main.js"
  }
}

This is my package.json.

Answer 1

Working backwards from the error, the key lines in the error log are:

remote: npm ERR! Failed at the [email protected] install script.

Which tells us that bcrypt's install script is the culprit (not your app code)

remote: gyp ERR! stack Error: `make` failed with exit code: 2

Which shows an error when node-gyp was running make which is used to compile native addons to node. and:

remote: node-pre-gyp WARN Pre-built binaries not installable for [email protected] and [email protected] (node-v57 ABI, glibc) (falling back to source compile with node-gyp) 

Which tells us that node-pre-gyp initially tried to download a pre-built version of bcrypt to save you the hassle of compilation, but failed because there's isn't a pre-built version of bcrypt 3 for node 8.

This means that if we find a version of bcrypt that works for the node version, we should be good! The version compatibility table tells us:

| Node Version | bcrypt Version | 
| ------------ |:--------------:|
|      8       |    >= 1.0.3    |
|    10, 11    |      >= 3      |

So you want a version of bcrypt between 1.0.3 and 3.0.0.

Looking at the versions tab on npm, we see the latest version that fits is 2.0.1

So you want to change the version in your package.json to 2.0.1:

  "dependencies": {
    "bcrypt": "^2.0.1",
    ... etc

While you're at it, you should probably remove bcryptjs if you're using bcrypt, and node-pre-gyp, as it's very unlikely your actual application is using that in production

In fact, that'd be why node-pre-gyp install is telling you that you're not "node-pre-gyp ready", just remove node-pre-gyp
