运行npm run dev报错的问题

源自：1-2 Webpack 安装和命令行

1、按老师的要求打包报错，网上说我本地的webpack版本太高，改用命令

webpack hello.js -o hello.bundle.js

2、dev和build环境都配置完成之后，运行npm run dev报错，错误内容如下：

npm ERR! code ELIFECYCLE

npm ERR! errno 1

npm ERR! webpack-test@1.0.0 dev: `webpack --mode development`

npm ERR! Exit status 1

npm ERR!

npm ERR! Failed at the webpack-test@1.0.0 dev script.

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
