关于警告：不赞成通过主React包访​​问PropType。 使用npm中的prop-types包

Question

我正在用酶开玩笑，但是我正在尝试测试的类中特别是从react-router依赖项收到上述警告。 我的问题是，为什么我已经将我的React版本降级到15.1.1，所以收到此警告。

我不想从Router v2升级到最新版本4，因为我必须在代码中进行很多升级。 为什么会出现此错误，尽管我没有使用最新版本的React，该版本的包已从“反应”更改为“道具类型”。

Answer 1

从React 15.5.0开始，PropTypes不再是react包的一部分，现在是它自己的单独包。 因此，如果您想摆脱警告，则需要npm install prop-types然后import PropTypes from 'prop-types'

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

Answer 2

如果您将React节点模块降级，请确保删除node_modules目录并重新安装它们。 您的其他依赖项很可能也已升级。 由于您没有固定版本，因此可能会出现在同一位置。 我会固定您的版本或使用yarn来生成yarn.lock文件。

Answer 3

React Router已更新软件包，以处理React库对'createClass'和PropTypes 。

版本2

看起来好像他们没有更新这个。 这是有道理的，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 ）
