根据官网搭建环境，创建项目，yarn iOS报错

[GentleCai-CH]

问题的具体描述

根据官网搭建环境，创建项目，yarn iOS报错。途中 xcode的ios模拟器的安装，与官网有出入，因为xcode不太一样。

另外xcode不能打开RN项目，只能打开RN项目里面的iOS目录。

报错信息如下：

error Failed to build ios project. "xcodebuild" exited with error code '65'. To debug build logs further, consider building your app with Xcode.app, by opening 'AwesomeProject.xcodeproj'. Command line invocation: /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -project AwesomeProject.xcodeproj -configuration Debug -scheme AwesomeProject -destination id=CA73C2BF-CDE7-41A1-BFD0-0C5A3179D769

User defaults from command line: IDEPackageSupportUseBuiltinSCM = YES ...........

BUILD FAILED

xcode打开ios目录里的xcworkspace后缀文件

如果没有xcworkspace文件，就是pod没有初始化完成，在ios目录中运行pod install看具体报错

网络问题，需要代理

谢啦。并没有用。

那是你的代理配置有问题

问题解决了！ 重新多次创建项目，与之前有两点不同：

1、卸载安装过的react-native-cli命令行工具：

发现跟随官网搭建程序后，创建项目时，需要卸载安装过的react-native-cli命令行工具（尽管之前没有安装过），运行官网给的命令：

       npm uninstall -g react-native-cli @react-native-community/cli

2、创建项目过程中，提示安装cocoapods。安装cocoapods后，有出现一些提示，其中有：

 Run instructions for iOS:
    • cd "/Users/gentle/Downloads/rnpj/AwesomeProject/ios"
    
    • Install Cocoapods
      • bundle install # you need to run this only once in your project.
      • bundle exec pod install
      • cd ..
    
    • npx react-native run-ios
    - or -
    • Open AwesomeProject/ios/AwesomeProject.xcodeproj in Xcode or run "xed -b ios"
    • Hit the Run button

主要是运行了这两句，安装了不同的依赖

• bundle install # you need to run this only once in your project.
• bundle exec pod install

后面创建的项目就都有 xxx.xcworkspace文件了。

小白不懂，只记录客观流程。

问题解决了，貌似不是网络问题
