离子模拟器上的错误

Question

I am just starting my adventure with mobile app development (and with ionic). I try to emulate a sample ionic project which I created with ionic start blank. Running

ionic emulate android 

returns the following error:

Running command: /home/ja/Projects/test/hooks/after_prepare/010_add_platform_class.js /home/ja/Projects/test

Could you please help?

Thanks in advance

EDIT

My .bashrc contains the following:

export ANDROID_SDK=/home/ja/android-sdk-linux/
export ANDROID_NDK=/home/ja/android-sdk-linux/
export ANDROID_HOME="$ANDROID_SDK"
export ANDROID_PLATFORM_TOOLS="$ANDROID_SDK/platform-tools"
export ANDROID_TOOLS="$ANDROID_HOME/tools"

export PATH=${PATH}:$ANDROID_SDK:$ANDROID_NDK:$ANDROID_HOME:$ANDROID_PLATFORM_TOOLS:$ANDROID_TOOLS

export ANDROID_EMULATOR_FORCE_32BIT=true 

Answer 1

Seems like the 'emulator-5554' device can't be found.

Try to reset the adb server.

adb kill-server
adb start-server

There are some issues which can be solved by this one. Source: Stack Overflow answer on a related question.

According to your logs:

Error executing "adb -s emulator-5554 shell getprop init.svc.bootanim": error: device 'emulator-5554' not found

It means you haven't created emulator. It might happen you have created then try to create one more emulator and then try emulate command.
