Cannot read property 'tapAsync' of undefined

I found this issue. But it didn't solve my problem. #180

I still get this error：

D:\work\kefu\front\node_modules\webpack-stream\index.js:198
        ? function (callback) { compiler.hooks.afterEmit.tapAsync('WebpackStream', callback); }
                                                         ^
