IT技术 - Material-ui v4无法为每个组件读取未定义的属性“根” - 吾爱随笔录

我已经从Material-UIv3 迁移到 v4。现在，我导入的每个组件都会出现此错误：

app.js:3581 未捕获类型错误：无法读取
未定义的属性“根”

在 Button (app.js:3581)
在 renderWithHooks (app.js:126202)
在 updateForwardRef (app.js:127721)
在 beginWork (app.js:128925)
在 performUnitOfWork (app.js:132576)
在 workLoop (app. js:132616)

app.js:130381 组件出现上述错误：
in WithStyles(ForwardRef(Button)) (created by Rtl)
in StylesProvider (created by Rtl)
in Rtl (created by App)
in Provider (created by App)
in App

React 和 react-dom 已按照指南进行更新：

"react": "^16.8.6",
"react-dom": "^16.8.6",
"@material-ui/core": "^4.0.0-rc.0",
"@material-ui/styles": "^4.0.0-rc.0",

我已删除/node_modules并yarn.lock尝试过yarn，但每个组件都会出现错误。

也发现了这个问题，但没有任何解决方案...
