I got this error when running react-native app by running the command: npx react-native run-android
error Failed to launch emulator. Reason: No emulators found as an output of `emulator -list-avds`. warn Please launch an emulator manually or connect a device. Otherwise app may fail to launch
Checking adb device running and the command not found.
adb devices zsh: command not found: adb
The solution for Mac user is to edit .zshrc by add following:
# fix adb command not found alias adb='/Users/softmastx/Library/Android/sdk/platform-tools/adb' # fix No emulators found export ANDROID_HOME=$HOME/Library/Android/sdk export PATH=$PATH:$ANDROID_HOME/emulator export PATH=$PATH:$ANDROID_HOME/tools export PATH=$PATH:$ANDROID_HOME/tools/bin export PATH=$PATH:$ANDROID_HOME/platform-tools
Save it and don’t forget to restart zsh for the changes to take effect!
