믹아의 개발일기

npm i -g npm-check-updates
ncu -u
npm install

알아서 최신 버전으로 업데이트 된다

nodejs express 서버를 로컬에선 오차없이 실행되다가 서버에만 올리면 이상해지길래 timezone 문제라고 생각이 들었다.

sudo rm /etc/localtime
sudo ln -s /usr/share/zoneinfo/Asia/Seoul /etc/localtime

이후 nodejs 재실행하니 제대로 동작했다.

새로운 맥에서 ios 실기기 빌드하는데 해당 에러가 뜨면서 앱이 하얀화면에서 멈춰있었다.

[VERBOSE-2:FlutterObservatoryPublisher.mm(101)] Failed to register observatory port with mDNS with error -65555.
[VERBOSE-2:FlutterObservatoryPublisher.mm(103)] On iOS 14+, local network broadcast in apps need to be declared in the app's Info.plist. Debug and profile Flutter apps and modules host VM services on the local network to support debugging features such as hot reload and DevTools. To make your Flutter app or module attachable and debuggable, add a '_dartobservatory._tcp' value to the 'NSBonjourServices' key in your Info.plist for the Debug/Profile configurations. For more information, see https://flutter.dev/docs/development/add-to-app/ios/project-setup#local-network-privacy-permissions
Connecting to the VM Service is taking longer than expected...
Still attempting to connect to the VM Service...
If you do NOT see the Flutter application running, it might have crashed. The device logs (e.g. from adb or XCode) might have more details.
If you do see the Flutter application running on the device, try re-running with --host-vmservice-port to use a specific port known to be available.

로그는 이정도

해결방법은 "시스템 환경설정" 에서

그리고 다시 빌드를 하면 잘 된다

nextjs에서 useEffect가 아무리봐도 2번 실행시킬 코드가 아닌데 자꾸 2번 실행돼서 찾아봤다.

next.config.js 에서  reactStrictMode 를 false 로 변경하고 앱을 재실행하자.

[ Found a change in next.config.js. Restart the server to see the changes in effect. ]

const nextConfig = {
  reactStrictMode: false,
}

됐다

Flutter 3.0 업데이트 후 iOS 빌드를 하려고 하니 나온 에러.

해결법

flutter pub upgrade --major-versions // 현재 프로젝트의 패키지 버전을 최신버전으로 업그레이드
flutter clean
rm pubspec.lock // pubspec.lock 파일 삭제
flutter pub get
