Building my project with the plugin... Config is just copy & pasted from document.
Than it failed.........

ENV

npm -version
5.6.0

webp-webpack-plugin
^1.2.6

html-webpack-plugin
^3.2.0

OS Platform:
Windows 10

webpack Version:
^4.16.0

code

Configuration file plugin section:

new WebPWebpackPlugin(
    {
        match: /(jpe?g|png)$/,
        webp: {
            quality: 80,
            inject: true, // inject the default runtime code
            injectCode: '' // inject your code
        }
    }
),

Exactly the same as the README shows.

This is project doesn't seem to support Webpack 4 at the moment. I also stumbled across this problem.

Sorry, this package doesn't support webpack 4 now. I will support it in the feature. And welcome to pull requests to support it.
