如何解决 TypeError: undefined is not an object (evaluating '_reactNative.Text.propTypes.allowFontScaling')

Question

我升级了 expo 并使用了 react-native-star-rating 并且我得到：

 ERROR  TypeError: undefined is not an object (evaluating '_reactNative.Text.propTypes.allowFontScaling')
 ERROR  Invariant Violation: "main" has not been registered. This can happen if:
* Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.
* A module failed to load due to an error and `AppRegistry.registerComponent` wasn't called.

我看到了一些关于这个补丁的东西，但我不知道我是怎么做到的

Answer 1

只需 go 到 node_modules/react-native-button/Button.js

并添加

import {TextPropTypes} from 'deprecated-react-native-prop-types'

将'static propTypes'更改为

static propTypes = {
...
allowFontScaling: TextPropTypes.allowFontScaling,
...
style: TextPropTypes.style
styleDisabled: TextPropTypes.style,
...
};

显然，您必须先 npm 安装 deprecated-react-native-prop-types 然后执行上述操作。 希望能帮助到你
