问题

我的Mac上安装了android studio，但是我要再命令行使用 emulator ，所以我配置了环境。

ANDROID_HOME="/Users/yourname/Library/Android/sdk"
export PATH=${PATH}:${ANDROID_HOME}/tools
export PATH=${PATH}:${ANDROID_HOME}/platform-tools

然后再命令行 输入 emulator -avd Pixel_4_XL_API_25，报错：

[4408659392]:ERROR:android/android-emu/android/qt/qt_setup.cpp:28:Qt library not found at ../emulator/lib64/qt/lib
Could not launch '/Users/yourname/Library/Android/sdk/../emulator/qemu/darwin-x86_64/qemu-system-i386': No such file or directory

找到了解决办法：

最简单的就是添加一个 alias:
alias emulator=${ANDROID_HOME}/emulator/emulator

后来又看到一个解决方案如下：

# Make sure emulator path comes before tools. Had trouble on Ubuntu with emulator from /tools being loaded instead of the one from /emulator
export PATH="$ANDROID_HOME/emulator:$ANDROID_HOME/tools:$ANDROID_HOME/tools/bin:$ANDROID_HOME/cmdline-tools/latest:$ANDROID_HOME/cmdline-tools/latest/bin:$ANDROID_HOME/platform-tools:$PATH"

即保证 $ANDROID_HOME/emulator 在$ANDROID_HOME/tools之前，其实道理和前一个解决方案一样，都是因为调用了$ANDROID_HOME/tools目录下的emulator而不是$ANDROID_HOME/emulator 中的emulator。
