[macOS] react-native run-ios、pod installでエラー


stack overflowとqiitaにお世話になりっぱなしね


macOS 10.15.5
XCode 11.6
Node.js v12.18.3
react-native-cli: 2.0.1
react-native: 0.63.2

npm installが無事完了できたので、react-native run-iosしたところ、次のエラーが。

$ react-native run-ios error Could not find "Podfile.lock" at /xxx/yyy/ios/Podfile.lock. Did you run "pod install" in iOS directory? info Found Xcode project "yyy.xcodeproj" xcrun: error: unable to find utility "simctl", not a developer tool or in PATH error Could not get the simulator list from Xcode. Please open Xcode and try running project directly from there to resolve the remaining issues. Run CLI with --verbose flag for more details. Error: Command failed: xcrun simctl list --json devices xcrun: error: unable to find utility "simctl", not a developer tool or in PATH

iosディレクトリにcdして、pod installしましたが、podコマンドがないとのこと。

$ cd ios $ pod install -bash: pod: command not found


$ sudo gem install -n /usr/local/bin cocoapods


react-nativeプロジェクトのiosディレクトリで、再度pod installしました。次のエラーが。Installing Flipper-Glog (0.3.6)の次から、赤い文字表示です。

Command Line Toolsのパスを/Applications/Xcode.app/Contents/Developer にすると、いいようです。

XCodeインストール後に、自力で Command Line Toolsをインストールすると、Command Line Tools のパスが/Library/Developer/CommandLineTools になってしまう、glog(Fligger-Glog)は、この状態を想定していないらしく、エラーになってしまう、と理解しました。

$ xcode-select -print-path /Library/Developer/CommandLineTools $ sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer $ xcode-select -print-path /Applications/Xcode.app/Contents/Developer

再度、pod installしたところ、無事完了しました。

react-nativeプロジェクトの直下のディレクトリに戻り、react-native run-iosしました。iOSシミュレータが起動し、アプリが表示されました。
