我在React(使用Redux和Antd),ASP.NET和C#中继承了一个项目,实际上我收到了数百种以下类型的错误:
TS2605(TS)JSX元素类型“ xxx”不是JSX元素的构造函数。
给我代码的程序员声称他们没有“拥有”这些错误(因此,由于代码无论如何编译,它们可能只是忽略它们)。我认为这可能与我的React版本有关(我有最新版本)。变通方法是由不同的资源(请参见下文)建议降级,但这不是我的选择。
我测试了导入React的不同方法,但是并没有减少错误的数量。在以下示例中,我在Visual Studio(专业版2017)中看到带下划线的红色代码:
import * as React from "react";
// ...
import { DatePicker } from "antd"; // I also load other things from antd
const { MonthPicker } = DatePicker;
// ...
<MonthPicker
format="MMMM YYYY"
style={{ width: 150 }}
placeholder="Date"
onChange={(e) => { this.handleSelectorChange("Date", e) }}
value={this.props.selectedDate !== null ? moment(this.props.selectedDate) : null}
/>
换句话说,用户定义元素xxx
以及标准元素MonthPicker
均会发生错误。 错误的确切含义是什么,我该如何解决?
有趣的是,尽管发生错误,该项目仍然可以运行。

如果您在以前运行的代码中到处都有它们,则可能是依赖性问题。我会尝试通过删除node_modules
并运行yarn install
或npm install
(取决于您所使用的软件包管理器)来重新安装所有内容。另外,请尝试将react
,react-dom
,@types/react
和@types/react-dom
软件包更新到最新版本,例如
npm install --save @types/react-select -D

您可以尝试删除package.lock.json
,然后运行npm i
。这可能会解决问题。
