TypeError:无法读取未定义(material ui )的属性'isRequired‘

Question

我试图从@material-ui/core@3.9.3切换到material v4.4.3的最新当前版本，但是我得到了这个错误

​

​

对于我来说，不清楚这个问题发生在哪段代码中，以及如何修复它。也许有人对此有一些想法？另外，你可以在package.json文件中检查我的所有依赖项。请让我知道你需要哪些信息，如果它不清楚，我会附上它。

Answer 1

我也有同样的问题。更新prop-type包对我很有效。我使用的是prop-types@15.6.0版本，但material v4将prop-types@^15.7.2声明为依赖项。因此，请尝试在应用程序中干净地安装prop-type。这对我很有效。

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

我是怎么想的:如果你点击了SelectInput.js:361，它会把你带到下面这一行

它解析为prop-type包。

希望这能有所帮助

尝尝这个,

import {PropTypes} from "prop-types";
