reactjs - TypeError：无法读取未定义的属性“isRequired”（材料 ui）

Question

我试图从@material-ui/core@3.9.3材料切换到最新的当前版本v4.4.3，但我遇到了这个错误

我不清楚这个问题发生在哪段代码中以及如何解决它。也许有人对此有一些想法？此外，您可以在 package.json 文件中检查我的所有依赖项。如果不清楚，请告诉我您需要哪些信息，我会附上。

我只是有同样的问题。更新 prop-types 包对我有用。我在版本上，prop-types@15.6.0但材料 v4 状态prop-types@^15.7.2为依赖项。因此，请尝试在您的应用程序中干净地安装 prop-types。这对我有用。

  npm uninstall prop-types;
  npm install --save-exact prop-types@15.7.2;

我是怎么想出来的：如果你点击 SelectInput.js:361 它会把你带到这一行

解析为 prop-types 包。

希望这可以帮助
