error getting eslint to work with eslint-plugin-vue

Question

I'm not a front-end dev but am trying to lint my javascript / Vue.js file in a Rails 5.1 app. I'm not that familiar with the node ecosystem. I get the following error and wanted to know where to start to fix this:

Tue Apr 17$ eslint javascript/ --ext .vue
Cannot find module 'eslint-plugin-vue'
Referenced from: /Users/jt/repos/embers2/.eslintrc.js

Tue Apr 17$ 

My .eslint.js file is:

module.exports = {
  extends: [
    // add more generic rulesets here, such as:
    // 'eslint:recommended',
    'plugin:vue/essential',
    'airbnb-base'

  ],
  rules: {
    // override/add rules settings here, such as:
    // 'vue/no-unused-vars': 'error'
  }
};

and my package.json is:

{
  "dependencies": {
    "@rails/webpacker": "^3.4.3",
    "axios": "^0.17.1",
    "coffeescript": "1.12.7",
    "octicons": "^6.0.1",
    "postcss-smart-import": "^0.7.6",
    "solc": "^0.4.19",
    "vue": "^2.5.16",
    "vue-awesome": "^2.3.4",
    "vue-cookie": "^1.1.4",
    "vue-loader": "^14.2.2",
    "vue-moment": "^3.2.0",
    "vue-octicon": "^2.1.1",
    "vue-progressbar": "^0.7.3",
    "vue-router": "^2.7.0",
    "vue-template-compiler": "^2.5.16",
    "vue2-google-maps": "^0.8.10",
    "vuex": "^3.0.1"
  },
  "devDependencies": {
    "eslint": "^4.19.1",
    "eslint-config-airbnb-base": "^12.1.0",
    "eslint-plugin-import": "^2.11.0",
    "eslint-plugin-vue": "^4.4.0",
    "extract-text-webpack-plugin": "^3.0.2",
    "vue-masonry-css": "^1.0.1",
    "webpack-cli": "^2.0.13",
    "webpack-dev-server": "2.11.1"
  }
}

Where do I start looking to debug this? This ecosystem is still very opaque to me.

On a comment's request, I ran npm install and verified that the plugin appears to be in ./node_modules/:

But I'm still getting the same error. Any other ideas?

You need to set the eslint working directories in .vscode/settings.json as following

{
  "eslint.workingDirectories": [
    "./client",
  ]
}

Here, ./client path is relative to where you initiated your visual studio code i.e. where your project root is
