ios - React Native - iOS - 无效的`Podfile`文件:nil:NilClass的未定义方法`[]'
问题描述
我刚刚开始使用 React Native。我正在关注官方文档中的 React Native CLI 快速入门。这也意味着我是最新的 React Native 版本0.61.2。
从那以后,我做了一些基本的 UI,在 iPhone 模拟器中检查结果。它在运行时工作react-native run-ios
,并没有真正接触ios/Podfile太多。
我的问题是在我的ios/文件夹中运行pod install总是会导致错误!现在这成为一个问题,我需要安装其他软件包。但是默认 Podfile 已经失败了!
错误信息:
[!] Invalid `Podfile` file: undefined method `[]' for nil:NilClass.

我不知道如何处理这个!我不知道 Podfile 和带有 xcode 文件的东西是如何工作的!我试图删除完成重置的文件夹。不仅如此,我不知道错误消息可能意味着什么。
解决方案
当您 cd 到 ios 文件夹并运行“pod install”时会发生此错误,这是因为您添加了一个新的 react native 模块
npm -i包
而不是使用纱线
纱线添加包
要解决此问题,只需转到 package.json 所在的主要 react native 项目文件夹,然后再次运行以下命令
纱线缓存清理
纱线添加包
然后尝试cd到ios文件夹并运行“pod install”,不会再有错误了。希望这可以帮助同样面临同样问题的其他人。
