javascript - 带有 React Native 的 Typescript 2.0

Question

我刚刚开始使用 Typescript，我正在尝试将它用于一个新的 React Native 项目。但是，我可以让 TS 进行编译。我的设置基于 this article使用 npm @types 除外。我在我的 IDE (Atom) 中获得了正确的类型提示，但是当我尝试编译时，我收到以下错误:

node_modules/@types/react-native/index.d.ts(19,24): error TS2307: Cannot find module 'react'.
node_modules/@types/react-native/index.d.ts(222,28): error TS2304: Cannot find name 'Component'.
node_modules/@types/react-native/index.d.ts(1017,15): error TS2304: Cannot find name 'Ref'.
...

由于您使用的是 "typescript": "^2.0.3"，因此报告的错误是 issue .有解决此问题的方法，即使用 "moduleResolution": "node"。请注意，它不会使经典模块解析适用于之后的包。

@Leone:你的修复 "module": "commonjs" 将无法工作，因为 React Native 附带了 ES2015、require() 模块将导致 React Native 中的运行时错误。
