ESLint is not a constructor

Question

I have made the porting to eslint-webpack-plugin and I am getting the error "ESLint is not a constructor", the relevant snippet code is:

const ESLintPlugin = require('eslint-webpack-plugin');

  const plugins = [
    new webpack.DefinePlugin(productionEnvironmentVariables),
    new ESLintPlugin({
      overrideConfigFile: path.resolve(configPath, '.eslintrc.json')
    })
  ];

Any idea what is wrong? I have tried also with new ESLintPlugin() and ESLintPlugin({}).

Webpack version is ^4.44.2 Eslint version is ^6.8.0 eslint-webpack-plugin is ^2.1.0

Thank you in advance and regards.

You also need to install eslint >= 7 from npm, if you haven't already:

npm

npm i -D [email protected]

yarn

yarn add -D [email protected]
