找不到离子目标设备

Question

我有一个ionic3项目，我正试图在iPhonePlus8，12.4模拟器上运行它。但是，当我运行时：

ionic cordova emulate ios --target="iPhone-8-Plus" --verbose

它给了我一个错误：

** BUILD SUCCEEDED **

我尝试了不同的目标选项，如' iPhone -8-Plus'，iPhone8Plus，" iphone -8-Plus，12.4"，"DFB1E30F-AEC9-4089-8D16-2AC71FC6B704“( id在iPhone8 plus旁边，但没有任何成功。

如果我从xcode打开项目并从那里运行它，它可以正常工作。

有什么想法吗？谢谢

Answer 1

您必须运行以下命令：

ionic cordova run ios --livereload --target "BA4986B3-9102-4250-91BF-7DDF7D7BC60D"

其中，target是列表中的设备Id

Answer 2

事实证明，来自$ cordova emulate --list的结果与来自$ native-run --list的结果不同(您运行这两个命令，您将看到设备名称不同)。

缺省情况下，Ionic CLI uses native-run会运行模拟器，因此您使用emulate --list命令获得的设备名称将不会匹配。您需要使用cordova运行您的应用程序，而不是通过添加标志--no-native-run来运行

$ ionic cordova emulate ios --target="iPhone-8-Plus" --no-native-run

ionic cordova run

此命令将首先使用ionic build来构建web资源(或使用--livereload选项的ionic服务器)。然后，使用cordova build编译和准备您的应用程序。最后，本机运行的实用程序用于在设备上运行应用程序。要将Cordova用于此进程，请使用--no-native-run选项。
