在运行npm run dev时出现如下错误：

解决方案：
这个是因为当前版本的[email protected] 不支持 [email protected]这种高版本。因此，只需删除当前的webpack-dev-server文件夹，然后重装高版本即可。步骤如下：

1. 找到你创建的项目文件夹，我的是 D:\javaProject\vue\myvue\node_modules\webpack-dev-server，删除webpack-dev-server文件夹。
2. 在当前项目目录下执行npm i [email protected] -D，这样你的webpack-dev-server版本就没问题了。
3. 或者直接更新到最新版

npm i –-save-dev webpack-dev-server@next
