问题描述

我正在尝试安装 react-bootstrap.当我运行命令时

I am trying to install react-bootstrap. When I run the command

npm install react-bootstrap --save

我得到以下信息(一些路径名替换为..."):

I get the following (some path names replaced with '...') :

npm WARN saveError ENOENT: no such file or directory, open '/Users/../package.json'/Users/.../..

我是否需要在安装 react-bootstrap 之前安装 React ?我在 doc 中没有看到任何具体提及.(我是 React 的新手，如果我使用 react-bootstrap，我什至不知道我也需要 React.我认为它也包含 React.但是在同一 doc 稍后:如果你安装了 React 和 React-Bootstrap，你就拥有了你需要的一切.")

Do I need to install React before I install react-bootstrap? I don't see any specific mention of it in the 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 later: "If you have React setup and React-Bootstrap installed you have everything you need.")

推荐答案

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.

In the React ecosystem, you should always install react + react-dom first. Don't rely on peer dependencies in general.
