开始真机测试Demo时提示错误
info: [debug] Couldn't find ideviceinstaller, trying built-in at /Applications/Appium.app/Contents/Resources/node_modules/appium/build/libimobiledevice-macosx/ideviceinstaller
error: Could not initialize ideviceinstaller; make sure it is installed and works on your system
解决方法：
brew install --HEAD ideviceinstaller
真机测试无限闪退
info: [debug] [INST STDERR] Instruments Trace Error : Target failed to run: Permission to debug cn.com.10jqka.IHexin was denied. The app must be signed with a development identity (e.g. iOS Developer).
解决方法：线上应用一般为release版本，需要使用Debug版本
详细参考：Can't launch my app in Instruments: At least one target failed to launch
运行Python脚本报错
SyntaxError: Non-ASCII character '\xe7' in file CodeMakerTest.py on line 24, but no encoding declared; see [http://python.org/dev/peps/pep-0263/](http://python.org/dev/peps/pep-0263/) for details
解决方法：在脚本文件(第一行)添加
#coding:utf-8
appium真机测试无法启动app且报错
error: Could not pre-launch appium: Error: Instruments crashed on startup
解决方法：
-
设置-开发者-Enable UI Automation需要为打开状态 - 若做了第一步依然报错，先试着使用将手机用Xcode进行Demo真机测试

我用appium+ios真机测试，跑测试脚本无法连接真机上的WebDriverAgent，下面是appium日志，麻烦帮我看一下吧，谢谢~
