运行时出现错误webpack-dev-server --config config/webpack.dev.js --progress --profile --watch --content-base src/。这是错误日志：

如果您正在使用webpack-cli 4 or 网页包 5， 改变webpack-dev-server to webpack serve.

Example:

"serve": "webpack serve --config config/webpack.dev.js --progress"

NPM package.json脚本是一种方便且有用的运行方式 本地安装的二进制文件，而不必关心它们的 完整路径。只需这样定义一个脚本：

For webpack-cli 3.x:

"scripts": {   "start:dev": "webpack-dev-server" }

For webpack-cli 4.x:

"scripts": {   "start:dev": "webpack serve" }
