Webpack + React + TypeScript: Module not found ... in ... node_modules/react/
提问by Sandy Gifford
I'm trying to put together a very basic project with React, TypeScript and Webpack. When I compile I get the following errors from the reactfolder in node_modules(I've removed the stack traces and my project's path for brevity):
我正在尝试将一个非常基本的项目与 React、TypeScript 和 Webpack 放在一起。当我编译时，我从react文件夹中得到以下错误node_modules（为简洁起见，我删除了堆栈跟踪和我的项目路径）：

I tried uninstalling TypeScript and replacing it with Babel to transpile the JSX and got the same error. Installing babel-preset-2015fixed it.
我尝试卸载 TypeScript 并用 Babel 替换它以转译 JSX 并得到相同的错误。 安装babel-preset-2015固定它。
I've tried just about every combination of targetand modulein tsconfig.jsonto get the same result in TypeScript but couldn't get anything working. How can I get Webpack, TypeScript, and React working together?
我已经尝试了几乎所有target和modulein 的组合tsconfig.json以在 TypeScript 中获得相同的结果，但无法获得任何工作。 如何让 Webpack、TypeScript 和 React 协同工作？
I've worked with all three of these technologies before, is it a recent compatibility problem? If so what are the most recent compatible versions?
我以前使用过所有这三种技术，这是最近的兼容性问题吗？如果是这样，最新的兼容版本是什么？
I've seen a few other questions similar to this one where the solution was installing fbjsdirectly in the project - I've tried this too without success.
我已经看到了一些与此类似的其他问题，其中解决方案fbjs直接安装在项目中 - 我也尝试过但没有成功。

Webpack is not resolving .jsfiles. Add this to your webpack.config.js.
Webpack 不解析.js文件。将此添加到您的webpack.config.js.
resolve: {
extensions: [".ts", ".tsx", ".js", ".jsx"]
},
Here is the tsconfig.jsonI used to run your example.
这是tsconfig.json我用来运行您的示例的。
