我正在尝试构建正确的反应项目结构,以用于构建温度转换器。
问题 - 每次尝试通过类组件呈现JSx时,我都会收到以下错误:
exc_class
如何更正此问题?
配置和源目录的树结构:
APIKeyError
我认为导致错误的代码集是:
CelsiusComponent.js
api
InteractiveModel.js
Error: Element ref was specified as a string (container) but no owner was set. This could happen for one of the following reasons:
1. You may be adding a ref to a functional component
2. You may be adding a ref to a component that was not created inside a component's render method
3. You have multiple copies of React loaded
