上脚本：

配置 capacity

启动 Appium 服务器后，脚本的 console 报错信息如下：

selenium.common.exceptions.WebDriverException: Message: An unknown server-side error occurred while processing the command. Original error: Error executing adbExec. Original error: Command '/usr/local/android-sdk-macosx/platform-tools/adb -P 5037 -s 634f5ff9 install /Applications/Appium.app/Contents/Resources/node_modules/appium/node_modules/appium-android-driver/node_modules/io.appium.settings/bin/settings_apk-debug.apk' exited with code 1{"stdout":"","stderr":"adb: failed to install /Applications/Appium.app/Contents/Resources/node_modules/appium/node_modules/appium-android-driver/node_modules/io.appium.settings/bin/settings_apk-debug.apk: Failure [INSTALL_FAILED_ALREADY_EXISTS: Attempt to re-install io.appium.settings without first uninstalling.]\n","code":1}

我在网上查到的相关信息是 appium 版本与 android 7 系统存在不适配的情况。
请问大佬们有没有碰到过相关问题，和相对应的解决方法呢？

版本号情况：

Appium：v1.5.3
Selenium： 3.141.0
Python： 3.7
Android：7.1.1
