使用AS 创建了一个 ARM架构的模拟器，运行的时候由于安装过慢，导致安装appium基础配置包的时候，超时报错如下
Error: Command '/Users/juanxu/Desktop/software/android-sdk-macosx/platform-tools/adb -P 5037 -s emulator-5554 shell pm install -r /data/local/tmp/appium_cache/0cc1725a60a05dbb5d0d09256f2fc6ece7e3b10f.apk' timed out after 20000ms

解决：
desirecapability添加参数，延长超时时长：
“uiautomator2ServerInstallTimeout”: 60000
