昨天下午安装babel出错，一直在网上查解决方案都没找到，最后发现原来仔细阅读报错信息就可以解决。

报错信息如下：

PS E:\VSCode\work\1010\aaa> npm install --global babel-cli

## 背景： ##

尝试安装过很多次babel。

## 错误分析： ##

npm ERR! EEXIST: **file already exists**, cmd shim ‘C:\\Users\\lenovo\\AppData\\Roaming\\npm\\node\_modules\\babel-cli\\bin\\babel-doctor.js’ -> **'C:\\Users\\lenovo\\AppData\\Roaming\\npm\\babel-doctor’**

其中说得很清楚，是因为后面路径中的文件已经存在，导致产生不了新的文件。从而使得babel安装失败

## 解决方案： ##

找到前面被指向的路径，在此路径的文件中，把带有babel的文件全部删除，即可解决问题：
