vue报错：dependencies were not found: * element-ui in ./src/main.js * element-ui/lib/theme-chalk/display.css in ./src/main.js * element-ui/lib/theme-chalk/index.css in ./src/main.js

报错信息：

These dependencies were not found:

* element-ui in ./src/main.js

* element-ui/lib/theme-chalk/index.css in ./src/main.js

解决方案：

1、 cmd进入命令行窗口，切入运行的项目文件夹下

2、在cmd命令行窗口输入

cnpm i element-ui -S

没有cnpm的使用  如下代码：

npm i element-ui -S
