webpack 4.0 报错

ERROR in multi ./src/entery.js dist/bundle.js
Module not found: Error: Can't resolve 'dist/bundle.js' in 'D:vuejswebpack_demo'
@ multi ./src/entery.js dist/bundle.js main[1]

module not found:error:can't resolve‘./components/layer/layer.js’ in webpack-demo/src/app,js

webpack --mode production src/main.js --output-filename app.bundle.js --output-path dist

4.0以后需要写 --output-filename和--output-path
