嗨，我装的 appcrawler 的版本是 2.1.3，同时我装了两种方式的 appium（dmg1.5.3 和终端的 v1.7。2），xcode 的版本是 8，可我在每次运行 appcrawler 的时候显示的 log 如下：--------------------------------

我觉得应该是 appium 就没起来。我实际想用的是终端的 appium，我以为我在终端上运行了 appium 就默认使用了它，实际没有。。。我看 log 上显示的是 use appiumclient，

问题 1:我现在要怎么去设置才能解决这个问题呢。

问题 2:我是 ios 真机运行，手机上已经装了 app，包名的后缀是.ipa，可是我发现他总是提示找不到。这个我又要怎么设置呢
