【问题描述】:
我正在尝试在react-testing-library 中运行the example 来测试反应挂钩。但它似乎在这条线上失败了:
testHook(() => ({count, increment} = useCounter({ initialCount: 2 })))
看起来它与 Babel 有关。尝试谷歌搜索,但找不到任何似乎有同样问题的人。我用create-react-app 安装了webpack。
这是堆栈跟踪:

【问题讨论】:
-
我不确定如何解决 Babel 问题,但如果你写
testHook(() => { return ({count, increment} = useCounter({ initialCount: 2 }))}),它可以工作。可能他们正在使用一些您当前设置没有的高级 ES6 语法糖。 -
@tuchi35 是的,这对我也有用。如果您将此作为答案发布,我很乐意接受并投票。
