错误：所需的功能必须包括应用程序或 iOS 的 bundleId

Question

我使用的是 mac OS X 10.12，Appium 服务器 1.5.3，xcode 版本 8.3。如果我运行医生，那么它表明 appium 已正确安装。

但是，如果我启动 appium 服务器，并尝试启动检查器，我会收到一个错误，无法使用以下日志启动检查器。

Answer 1

出现再生器错误是因为 xCode 8 仅适用于 appium 1.6 +。

您可以参考：https://github.com/appium/appium/issues/6845

Answer 2

为应用路径添加所需的功能（例如） DesiredCapabilities.setCapability("app", "/Users/Library/Developer/Xcode/DerivedData/foldername/Build/Products/Debug-iphoneos/appname.app");

此外，您只需打开 appium GUI，保持选中 iOS 图标并在终端中启动 appium (1.6+) 服务器后点击检查器图标（不要在 GUI 中点击“启动”），即可打开 1.5.3 的 appium 检查器。
参考：https://discuss.appium.io/t/how-to-launch-appium-inspector-on-appium-1-6-0-beta2-as-there-is-no-appium-app-file-for-that-beta/12448/16

Answer 3

您需要添加功能“app”或“bundleId”。因为在您的情况下，它无法知道应该启动哪个应用程序。

capabilities.setCapability("app","path of your .app file");

Appium 1.5.3 与 xcode 8+ 不兼容。如果您已经通过终端安装了 appium，则通过运行命令通过终端启动 appium。

appium

此命令将启动 appium 服务器。请勿使用 appium 1.5.3。

请参考以下链接了解如何在安装 appium 1.6+ 后从终端启动和运行 appium
