使用命令行npm install element-plus --save 出现了上面的错误。
大致意思就是缺失了东西。
查了下，是缺啥安装啥。
使用了npm install babel/core@^7.0.0
报错了。

进入官方文档查询。运行如下命令：

npm install --save @babel/helper-compilation-targets

接着再次运行了npm install @babel/core@^7.0.0
出现了一个警告，但是没有出现error，大概是我之前少输入了一个@符号。

这个警告，进行了查询，被安装的原因就是：这个包是mac上可以选择的依赖，但是你使用了window的电脑，也安装了，可以看看你的package.json文件中是不是fsevents的相关依赖，删除就好；其实这个警告是因为mac需要这个包，但是你是在windows环境下，可以忽略这个警告。
强迫症可以按照如下方法，删除这个包：

①在package.json中添加这个对象

"optionalDependencies": {
    "fsevents": "*"
  }

②删除原来安装的包和生成的package-lock.json文件

③重新执行安装命令

npm install --no-optional
