我正在尝试在当前项目中安装react-tinder-card。所以我想安装react-tinder-card，但是在使用命令之后
npm install-保存react-tinder-card
我在控制台中看到的全部是：

我不明白那是什么意思。请帮助我找到解决方案。任何帮助将不胜感激。 预先谢谢你。
答案 0 :(得分：9)
这个错误基本上是说它的对等依赖项中的 react-tinder-card@1.3.1 有 react@"^16.8.0"。所以它需要那个版本的 react 才能正常运行。在您的 tinder-clone@0.1.0 应用程序中，您目前拥有 react@17.0.1。
这个问题可以手动解决，只需安装react-tinder-card@1.3.1需要的react@"^16.8.0"版本的react，所以你需要降级你的版本来运行包。
--legacy-peer-deps 标志是在 npm 的 v7 版本中引入的，作为绕过 peerDependency 自动安装的一种方式；它告诉 NPM 忽略对等节点并继续安装。这可能会导致一些不需要的行为，我不建议这样做。

降级到 npm v6。它应该可以解决问题。
npm install -g npm@6
答案 2 :(得分：2)
此错误来自npm的7.x版本。
请使用--legacy-peer-deps选项重试。
答案 3 :(得分：2)
$ npm install --save react-tinder-card --legacy-peer-deps
答案 4 :(得分：0)
我上面也有同样的错误。我安装了 npm v6.7。我重新安装了 Netlify CMS 和 Gatsby：
npm install netlify-cms-app@2.9 gatsby-plugin-netlify-cms@^4.0.0
除了 favicon.ico 文件之外，我在静态文件夹下没有任何东西。没有管理文件夹和 .yml 文件。
