webpack - Property context does not exist on type NodeRequire

Solution from 2018:

Just install the typings for webpack-env

npm i @types/webpack-env -D

And in tsconfig.json add it in the types property example:

 {
  "compilerOptions": {
    "outDir": "./dist/",
    "declaration": true,
    "declarationDir": "./dist/",
    "sourceMap": true,
    "noImplicitAny": false,
    "module": "commonjs",
    "target": "es6",
    "allowJs": false,
    "types": [
      "node",
      "webpack-env" // here
    ]
  },
  "files": [
    "src/index.ts"
  ],
  "compileOnSave": false
}
