Vue webpack ERROR in multi ./src/main.js dist/bundle.js

原命令
webpack .srcmain.js .distundle.js
报错
ERROR in multi ./src/main.js ./dist/bundle.js
Module not found: Error: Can’t resolve ‘.distundle.js’ in ‘C:UsersTecna1205Desktopvuewebpack-study’
@ multi ./src/main.js ./dist/bundle.js main[1]

当webpack版本到达4，需更换命令为
webpack .srcmain.js -o .distundle.js --mode development

这样就可以生成bundle.js了
