关于警告：不推荐通过主 React 包访问 PropTypes。改用 npm 中的 prop-types 包

Question

我运行和酶开玩笑，但我收到上述警告，特别是来自 class 我正在尝试测试的 react-router 依赖项。我的问题是为什么我会收到此警告，因为我已经将我的 React 版本降级到 15.1.1。

错误的完整堆栈跟踪是：

我不想从路由器 v2 升级到最新版本 4，因为我必须在我的代码中进行大量升级。尽管我没有使用最新版本的 React，但此包已从 'react' 移动到 'prop-types'。

为什么会出现此错误

Answer 1

如果您降级了 React 节点模块，请务必删除 node_modules 目录并重新安装它们。很可能您的其他依赖项之一也已升级。由于您没有固定您的版本，您可能最终会在同一个地方。我会固定你的版本或使用 yarn 生成一个 yarn.lock 文件。

Answer 2

从 React 15.5.0 开始，PropTypes 不再是 react 包的一部分，现在是它自己的独立包。所以如果你想摆脱警告你需要 npm install prop-types 然后 import PropTypes from 'prop-types'

TestUtils 也一样： https://facebook.github.io/react/blog/2017/04/07/react-v15.5.0.html#react-test-utils

Answer 3

React Router 已更新包以处理 'createClass' 和 PropTypes 的 React 库更改。

版本 2

他们好像没有更新这个。有道理，因为版本 4 是最新的。

版本 3

https://github.com/ReactTraining/react-router/releases/tag/v3.0.4

（尽管您可能会安全地使用 3.0.5）
