当我尝试使用npm start运行React应用程序时，它失败并出现类型错误：no-undef和no-restricted-globals，而它实际上编译并运行时没有任何问题我同事的机器！
我更改了我的npm和node版本以匹配其他计算机上的版本，但我得到了相同的结果。
任何想法在版本中的其他地方都可能出现问题吗？
以下是所有错误：

is not defined no-undef表示未声明或导入。例如
PropTypes需要导入，如import PropTypes from 'prop-types';。如果您这样做，请确保您已经运行npm install。
或者确保重新安装依赖项。删除node_modules文件夹，
然后在该npm cache clean之后运行npm install。

感谢大家，感谢您尝试解决我的问题。问题原来是在掉毛！ create-react-scripts似乎有自己的缘故。当我安装eslint时，错误开始仅显示为警告，因此我现在看到not defined警告，而不是not used错误。至少应用程序工作，我可以处理删除未使用的变量。
再次感谢！
