我遵循以下指南:

但是当我到达运行expo run:ios的步骤时,它失败了,并出现以下错误:

我不确定我做错了什么Xcode说了下面的语句
CommandError: Failed to build iOS project. "xcodebuild" exited with error code 65.
我安装了最新的Expo CLI
我试着直接在Xcode中构建项目,项目确实构建了,但它不会在模拟器上启动,expo打开,但当连接到开发服务器时,应用程序崩溃。
我不明白为什么运行expo run:ios会导致构建失败,而在Xcode中构建会导致“成功”。

这个解决方案其实有点傻,
所以我能在Xcode中成功构建而不能使用expo run:ios成功构建的原因是因为我在这台机器上安装了两个版本的Xcode。一个版本是Xcode 12. 3,并且xcrun指向了那个sdk包。我可以通过运行sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer来修复这个问题,仔细检查xcrun --show-sdk-path现在应该列出适当的路径。我删除了pod文件和pod.lock文件,并使用expo run:ios重新构建了应用程序
