我最终升级了 ios 版本并使用 Rosetta 运行了 iterm2，Pod 安装终于成功了。当我应该使用cd ios/ && pod install时，我也在使用npx pod install

原创

我正在设置一台新的笔记本电脑，终于开始重新构建我的 React 本机应用程序，但遇到了 npx pod install 的问题。

npx pod install

当我查看这些 npx 目录时，它们在 node_modules 中从来没有任何内容。

【问题讨论】：

你到底想做什么？在快速浏览 pod 文档时，我没有看到 pod install 作为命令。

抱歉 @Trott 我从 npx pod install 命令中修剪了其余的日志。其余的日志行是关于不推荐使用的包。

【参考方案1】：

查看pod package.json file，它似乎依赖于安装在模块自己的node_modules 目录中的pm2，但这不是npx 做事的方式。这就是为什么您会收到 pm2 模块的 ENOENT（基本上是“找不到路径”）作为您的错误消息。

最简单的解决方案可能是不使用npx 和pod，而是使用the README instructs 并将pod 安装为带有npm install -g pod 的全局包。然后运行pod install 而不是npx pod install。

【讨论】：

谢谢。我的命令错误，所以最终它是旧 iOS 版本的组合，而我使用了错误的命令，让我陷入了这个困境。很抱歉浪费了您的时间。
