带有“ use_native_modules！”的react-native ios Podfile问题！

Question

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

[!] 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-它们都是react-native生成的。（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！

这是我的Podfile

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

target 'hhs2' do
  # Pods for hhs2
  pod 'React', :path => '../node_modules/react-native/'
  pod 'React-Core', :path => '../node_modules/react-native/React'
  pod 'React-DevSupport', :path => '../node_modules/react-native/React'

  pod 'Folly', :podspec => '../node_modules/react-native/third-party-podspecs/Folly.podspec'

  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

Answer 1

这是正确的答案：

1-您的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-如果在运行后未找到，则yarn install表示您的计算机中有旧的高速缓存node_modules，您需要先清理它，然后再重新安装该软件包。

4-清理缓存 yarn cache clean

5-确保您拥有此文件react-native.config.js且其配置为有效-并且它不存在不存在的NPM软件包-此步骤是最后且主要是错误原因

我的例子 react-native.config.js

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应该可以正常工作了！pod install --repo-update

祝您编码愉快！

Answer 2

将@react-native-community/cli-platform-ios 从 3.1.0 降级到 3.0.0 并且它起作用了。

添加

"@react-native-community/cli-platform-ios": "3.0.0"

到 package.json。

运行 npm install 然后 pod install 让它再次工作。

Answer 3

这是因为您的设备上的纱线版本已过时，如果您在 macOS 上，您可以通过以下链接升级/安装纱线： 这里是

请注意删除node-module并yarn.lock归档，再次安装所有软件包，导航到ios文件夹并运行pod install.

Answer 4

验证您的package.json@react-native-community/cli-platform-ios中是否有 ，

如果你不运行：

npm install @react-native-community/cli-platform-ios

然后

cd ios && pod install

Answer 5

如果您正在使用

pod install --project-directory=ios

您可能需要通过替换来调整 Podfile

use_native_modules!

到

use_native_modules!(".")

也许这种行为将来会得到改善，我打开了一个关于它的问题https://github.com/react-native-community/cli/issues/657
