React Native:<string>.matchAll 不是函数 [英] React Native: <string>.matchAll is not a function

问题描述

我在运行 React Native 应用程序时遇到一个奇怪的错误:

I get a weird error when running my React Native app:

一些示例代码:

const { url } = <incoming object>;
const reURL   = <my regex>;

console.debug('url:', url);
console.debug('typeof url:', typeof url);

matches = [...url.matchAll(reURL)];

日志输出:

url: <as expected>
typeof url: string

错误信息:

TypeError: url.matchAll is not a function. (In 'url.matchAll(reURL)', 'url.matchAll' is undefined)

在 iOS 上一切正常，错误仅在 Android 上发生.

Everything works fine on iOS, the error only occurs on Android.

最新的环境，几天前更新了所有 npm 包.

Pretty up to date environment, updated all npm packages a couple of days ago.

有没有人知道从哪里开始寻找解决方案?

Does anyone have the slightest idea where to even begin searching for a solution ?

推荐答案

你可以使用 string.prototype.matchall 来 polyfill.

You can use string.prototype.matchall to polyfill.

matchAll.shim()
