Vue项目启动报错处理

1、Error: Cannot find module 'webpack'

解决方式：

npm install --save-dev webpack

2、Error: Rule can only have one resource source (provided resource and test + include + exclude) in {

解决方式：

首先卸载原来的webpack包：npm uninstall webpack
然后重新再项目中安装低版本的：npm install webpack@^4.0.0 --save-dev

3、Syntax Error: Error: Cannot find module '@vue/babel-preset-app'

npm install @vue/babel-preset-app --save-dev

npm install --save-dev @babel/core

4、Syntax Error: Error: Cannot find module 'cache-loader'

5、解决Error: ENOENT: no such file or directory, scandir 'xxx\node-sass\vendor'

删除依赖，重新 cnpm install

6、解决 These dependencies were not found: * core-js/modules/es6.array.fill in xxx 之类的问题

在babel.config.js中添加：

presets: [ [ "@vue/app", { useBuiltIns: "entry" } ] ]

Error: Rule can only have one resource source (provided resource and test + include + exclude)

解决方案：

删除webpack，重新装以前的版本。

npm uninstall webpack
npm install webpack@^4.0.0 --save-dev
