在安装 react-bootstrap 之前是否需要安装 React
Do I need to install React before I install react-bootstrap
我正在尝试安装 react-bootstrap。当我 运行 命令
npm install react-bootstrap --save
我得到以下信息（一些路径名替换为“...”）：

我需要在安装 React-bootstrap 之前 安装 React 吗？我在后面的 doc. (I am new to React and didn't even know that I need React also if I am using react-bootstrap. I thought it included React as well. But saw this mentioned in the Javascript section of the same doc 中没有看到任何具体提及："If you have React setup and React-Bootstrap installed you have everything you need.")
在 React 生态系统中，您应该始终先安装 react + react-dom。一般不要依赖对等依赖。
是的，您需要分别安装 react 和 react-dom。对等依赖项是您正在安装的软件包假定已经安装的依赖项。
npm 3 中的行为发生了变化，只是警告那些缺失的内容。
npm install react react-dom react-bootstrap --save
