无法将SVG导入到Typescript应用中,在react-scripts start过程中抛出以下错误:

Failed to compile.

./src/components/Icons/Backward.svg (./node_modules/@svgr/webpack/lib?-svgo,+titleProp,+ref!./src/components/Icons/Backward.svg)
TypeError: Cannot read property 'children' of undefined

我是这样导入的:
import {ReactComponent as SomeName} from './some/svg/file.svg'

你尝试恢复依赖了吗?

是的,我已经重新安装了所有的依赖。但仍然显示错误。

你在用户指南中搜索了哪些术语?

SVG, Typescript

环境

npx create-react-app info 上我得到这个:

重现问题的步骤

我的伙伴用typescript模板创建了一个全新的CRA,对我来说它可以工作。
我创建了一个新的项目,将所有文件移动到新项目中,但它仍然无法正常工作。

预期行为

SVG文件应该被导入为React组件。

实际行为

无法正常工作)

我遇到了类似的问题。错误是 Attempted import error: 'ReactComponent' is not exported from '../../assets/images/tick.svg' (imported as 'TickIcon'). 。真希望我知道问题出在哪里,因为它在默认设置下可以正常工作,但在我的项目中却不行。

伙计,我的同事和我做了相同的设置,她的项目可以正常运行。她把代码推送到仓库,我拉取后,项目神奇地开始运行了......

对于发现此问题的人,临时解决方法是:将所有SVG导入到index.js(注意js扩展名),然后从JS中导出。这样它就不会处理类型了。
