Recharts 不适用于带有打字稿的 React

Question

我在处理图表库时遇到问题。

一步步

1. 创建一个空项目

$ npx create-react-app chart-demo --template typescript

2. 添加记录

$ yarn add @types/recharts

3. 运行项目

$ yarn start

它显示以下错误。

Failed to compile
./src/App.tsx
Module not found: Can't resolve 'recharts' in '\chart-demo\src'

仅供参考，它不仅适用于重新图表，还适用于几个图书馆。幸运的是，我发现胜利图表正在运行

新项目真的很新鲜，只是添加recharts而已。
请帮我弄清楚这个问题。

Answer 1

你没有安装 recharts，你只安装了它的类型定义。

尝试：

yarn install recharts

当你安装一个@types/<package-name>包时，你并没有安装任何可运行的代码。您只是为不提供自己类型的包安装类型定义。您仍然需要安装软件包本身。
