运行命令webpack ./src/main.js ./dist/murenziwei.js后，目录上神马动静都没有，你以为在dist文件夹上会有murenziwei.js吗？毛都没有

警告和错误倒是有，警告说我没有设置mode？错误说我配置打包出入口有问题？

为了快点打包成功，我老老实实的服从，将上面webpack命令改为webpack ./src/main.js --output-filename ./dist/murenziwei.js --output-path . --mode development，然后按下Enter，我的解决了，你的呢？

--output-filename：设置要打包的文件目录
--output-path：打包文件放置的文件目录
--mode：告诉程序，在当前目录，我是属于开发状态development

再来最后一眼，瞧瞧murenziwei.js都有啥？
