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

    at Config.getConfigHierarchy (/usr/local/lib/node_modules/eslint-config-airbnb-standard/node_modules/eslint/lib/config.js:180:43)
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?

Wherever your package.json file is, try dong npm install in the terminal/cmd. The npm package eslint-plugin-vue is not installed and this command will install all packages in package.json and overwrite those that exist already. — Rahul Desai

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

Man... any idea why this doesn't simply work for all directories out of the box?
