Cannot read property 'plugin' of null

npm-install-webpack-plugin stop systematically with this error

TypeError: Cannot read property 'plugin' of null
    at NpmInstallPlugin.apply (/home/alexandre/Project_tests/npm-install-webpack-plugin/example/webpack2/node_modules/npm-install-webpack-plugin/src/plugin.js:50:28)

I am using the example provided in this repository: https://github.com/webpack-contrib/npm-install-webpack-plugin/tree/master/example/webpack2

When running npm run start, dependencies seems to be resolve but not not the loaders

well until they push a release. this works for me =>

npm install webpack-contrib/npm-install-webpack-plugin --save-dev
