需要帮助:模拟器没有从Appium.app启动应用程序

Question

运行Appium应用程序自动化移动应用程序时遇到问题

下面是我使用的Appium版本:1.2.1Xcode: 5.1.1

以下是我正在做的步骤，

1. 下载Appium.dmg
2. 运行dmg文件，然后启动appium.app文件。
3. 用Xcode构建7.1仿真器应用程序
4. 在appium.app上，启用了‘App’选项，并提供了.app文件路径“/User/umairrashid/Library/Application Support/iPhone appium.app
5. 在“一般设置”中，服务器地址: 127.0.0.1，端口: 4723
6. 检查更新:已启用
7. 新的命令超时:7200秒

当我点击‘启动’按钮，那么一切似乎都好。

当我单击“检查器”按钮，然后显示以下错误时，

无法发射Appium探长

无法启动新的会话

确保Appium服务器运行时使用Appium.app中的"App“参数(以及用于Android的包和活动)打开应用程序，或者连接selenium客户端并在所需的功能对象中提供该参数。

在Appium控制台，我发现了以下错误，

在这里，我期望当我点击检查按钮从Appium，然后模拟器启动，我可以看到XPaths等在该视图。

Answer 1

1. 你确定你选中了苹果的图标吗(有时我们会做愚蠢的错误点击)
2. 如果您已经检查过“强制装置”，请取消检查。

如果你还有问题，最好是把你的appium gui截图发到这里，这样我就可以帮你更多的忙了。

Answer 2

您确定通过将Appium.app拖到应用程序文件夹中已安装了Appium吗？

下面的错误消息建议您只是从DMG文件中启动它。
