【问题描述】：

我正在捆绑一个 typescript react 组件包，我想知道当用户安装 react 组件包时是否有办法忽略 react 和 react-dom。

如果我不从节点模块中删除 react 和 react dom，用户将遇到此问题

错误：无效的挂钩调用。钩子只能在体内调用的一个功能组件。这可能发生在以下情况之一原因：

如果我从节点模块中删除了 react 和 react dom，组件将正常工作。我不想一直来回删除节点模块。我怎样才能简化这个？

我如何告诉 package.json 忽略节点模块中的 react 和 react dom？

【解决方案1】：

您基本上已经通过将 react 和 react-dom 放在 peerDependencies 下来告诉 npm 这样做。这告诉 npm 不要为你的包安装 react 和 react-dom，而是假设正在使用你的包的项目已经有 react 和 react-dom 作为依赖项。

尝试将 react 和 react-dom 添加到 webpack 配置的 externals 属性。这告诉 webpack 不要将它们与您的组件一起打包，并且应该减少版本冲突。
