【问题描述】：

我已经安装了 @types/react-dom 以及 typescript 和 @types/react 和 @types/meteor 但是当我尝试从命令行运行 typechecker 时出现以下错误

【参考方案1】：

React 16 beta 的类型已作为“最新”的 React 类型发布。

新版本移除了 React 16 中已移除的部分定义（如 React.DOM），这是意料之中的。

不幸的是，这些类型的 React 16 beta 发布是在 npm 中的 @latest（默认）标签上完成的，而不是 @next（就像 React 所做的那样）。

我有一个未解决的问题 (#18708)，这里是“DefiniteTyped”：https://github.com/DefinitelyTyped/DefinitelyTyped/issues/18708

您可以尝试专门针对特定版本 (npm install --save @types/react@15.6.0)，但 @types/react-dom 中 @types/react 的依赖项设置为“*”，这似乎导致 @types/react@latest 仍然被下载，导致您在 node_modules 目录的不同位置有多个版本。

我们不得不做一些手动工作来解决这个问题。希望维护@types/react 的人能尽快解决这个问题。

【参考方案2】：

我正在使用 yarn，并通过运行 rm -rf node_modules && rm yarn.lock && yarn install 解决了这个问题

【讨论】：

只是为了让人们意识到——如果你依赖 yarn 作为包管理器，那么这个命令就破坏了yarn 的全部目的。虽然它确实解决了这个问题 :) 另一方面，你可以运行 npm install 来代替
