带有“ use_native_modules！”的react-native ios Podfile问题 [英] react-native ios Podfile issue with "use_native_modules!"

问题描述

在ios /目录中的react-native项目（react-native@0.60）中，我运行 pod install 并得到以下错误：

In my react-native project (react-native@0.60) in the ios/ dir I run pod install and get this error:

[!] Invalid `Podfile` file: no implicit conversion of nil into String.

 #  from /Users/coryrobinson/projects/hhs2/ios/Podfile:37
 #  -------------------------------------------
 #  
 >    use_native_modules!
 #  end
 #  -------------------------------------------

我没有在此Podfile中添加或更改任何内容-所有本机生成。 （我没有iOS开发经验，所以这可能是一个简单的解决方法，我只是不知道要寻找什么：-|）感谢您的帮助！

I haven't added or changed anything in this Podfile - it's all react-native generated. (I'm not experienced in iOS dev so this might be a simple fix, I just don't know what to look for :-|) Thanks for any help!

这里是我的Podfile

Here is my Podfile

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

target 'hhs2' do
  # Pods for hhs2

  target 'hhs2Tests' do
    inherit! :search_paths
    # Pods for testing
  end

  use_native_modules!
end

target 'hhs2-tvOS' do
  # Pods for hhs2-tvOS

  target 'hhs2-tvOSTests' do
    inherit! :search_paths
    # Pods for testing
  end

end

推荐答案

这是正确的答案：

1-您的POD文件的顶部应包含此行

1 - Your POD File should contain this line on top

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

2 - Make sure your package.json and node_module folders has this module installed

cli-platform-ios / native_modules

3-如果您在运行 yarn install 后未找到-表示您的计算机中有旧的高速缓存node_modules，则需要

3 - If you didn't find after you run yarn install - means you have old cache node_modules in your machine and you need to clean it before reinstalling the package again.

4-清理缓存纱线缓存清理

5-确保您拥有此文件 react-native.config.js 并且其配置为有效-并且它没有t具有不存在的NPM软件包-此步骤i s造成错误的主要原因是

5 - Make sure you have this file react-native.config.js and its configuration is VALID - and it doesn't have non-existing NPM packages - this step is LAST AND MOSTLY THE CAUSE of the error

我的 react-native.config.js

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

6-安装节点程序包纱线安装和您的吊舱现在应该可以正常工作！ pod install --repo-update

6 - Install node packages yarn install and your pods should work now! pod install --repo-update

快乐的编码！
