### 问题

npm下载包的时候，如果其依赖的其他包的版本和你本地已经安装的版本不一致会出现类似下面的提示：

```
$ npm install seven-food-form@2.0.6
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree

npm ERR! Found: seven-food-form@2.0.1

```

其实这不影响使用，我们仍然下载就行了，下载时添加参数`legacy-peer-deps`，如下
```
npm install seven-food-form@2.0.6 --legacy-peer-deps
```
