我用的是react-admin v3.1.4，我试着升级到v4，但是太难了。所以，当我试着回到以前的版本时，我发现了一个问题，这个问题没有运行。这是由于mui的版本与更新前的版本不同而引起的。我已经为此挣扎了好几天了。请帮助！

问题

因此，我想做的是更改嵌套的@material-ui/icons版本。

我想将react-admin的@material-ui/icons版本v4.11.3更改为v.4.2.1（之前版本）
这是我依赖的一部分。

├─ @material-ui/icons@4.2.1
└─ react-admin@3.1.4
   └─ @material-ui/icons@4.11.3 => ToDo : change to v4.2.1

我已经试过了。
1.删除node_modules和yarn install

1. yarn upgrade --depth 5
   这是我的包. json
