我刚刚开始使用React Native。我遵循的是官方文档中的React Native CLI快速入门。这也意味着我使用的是最新的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react-native run-ios时工作，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！这现在成为一个问题，我需要安装额外的软件包。但它已经失败了默认的Podfile！

错误消息：

[!] Invalid `Podfile` file: undefined method `[]' for nil:NilClass.

 #  from /Users/marcel/Projekte/WerBinIch/ios/Podfile:43
 #  -------------------------------------------
 #  
 >    use_native_modules!
 #  end
 #  -------------------------------------------

ios/播客文件

platform :ios, '9.0'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

target 'WerBinIch' do
  # Pods for WerBinIch
  pod 'FBLazyVector', :path => "../node_modules/react-native/Libraries/FBLazyVector"

  target 'WerBinIchTests' do
    inherit! :search_paths
    # Pods for testing
  end

  use_native_modules!
end

我不知道如何处理这个问题！我不知道Podfile和xcode文件是如何工作的！我试图删除文件夹完成重置。更重要的是，我不知道错误信息可能意味着什么。

xcode

这个错误发生时，你的cd到ios文件夹和运行“pod安装”，是因为你添加了一个新的React Native模块
npm -i * 软件包 *
代替使用Yarn
Yarn添加 * Package *
要解决此问题，只需转到package.json所在的主react原生项目文件夹，然后再次运行以下命令
Yarn缓存清理器
Yarn添加 * Package *
然后尝试cd到ios文件夹，运行“pod安装”，就不会有更多的错误了。希望这能帮助其他也面临同样问题的人。

这个回答很好地解决了我的问题：
react-native ios Podfile issue with "use_native_modules!"
正确答案如下：
1 -POD文件顶部应包含此行

require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

2 -确保您的package.json和node_module文件夹已安装此模块

cli-platform-ios/native_modules

3 -如果在运行yarn install后没有发现-表示您的计算机中有旧的缓存node_modules，您需要在重新安装软件包之前清除它。
4 -清除缓存

$ yarn cache clean

5 -确保您有此文件react-native.config.js并且其配置有效-并且没有不存在的NPM包-此步骤是最后一步，也是错误的主要原因 *

我的react-native.config.js示例

module.exports = {
  project: {
    ios: {},
    android: {},
  },
  assets: ['./assets/fonts/']
  dependencies: {}, // make sure this deps are all valid installed packages or empty if you don't need it
};

6 -安装节点软件包yarn install，您的pod现在应该可以工作了！$ pod install --repo-update
快乐编码！
