• 报错日志：

selenium.common.exceptions.WebDriverException: Message: An unknown server-side error occurred while processing the command. Original error: Could not sign with default certificate. Original error Command '/Library/Java/JavaVirtualMachines/jdk1.8.0_91.jdk/Contents/Home/bin/java -jar /usr/local/lib/node_modules/appium/node_modules/_appium-adb\@2.28.0\@appium-adb/jars/sign.jar /usr/local/lib/node_modules/appium/node_modules/_appium-uiautomator2-driver\@0.6.1\@appium-uiautomator2-driver/uiautomator2/appium-uiautomator2-server-debug-androidTest.apk --override' exited with code 1

下面是尝试解决方案

• sudo cnpm install appium-uiautomator2-driver 安装成功
• 手动把 appium-uiautomator2-server-v0.1.8.apk 安装到手机
• 手动把 appium-uiautomator2-server-v0.1.8.apk 复制/usr/local/lib/node_modules/appium/node_modules/_appium-uiautomator2-driver\@0.6.1\@appium-uiautomator2-driver/uiautomator2 目录

请问下哪位遇到过这样到问题？
