Ios xcodebuild DVT断言失败，返回“0”；意外发现两个活动代理设备“；

这才刚刚开始。除了运行

ionic run ios

，在它正常工作和导致此错误之间，我没有做任何事情

这是配置和完整错误输出：

到目前为止，我已经尝试了以下方法：

• 重新启动我的电脑
• 移除并重新添加离子平台
• 在ionic项目文件夹中搜索对这些设备ID的引用。（

  grep-Rl 0AFB07EE.

  和

  grep-Rl 7A73CA0B.

  ）
• 重置模拟器内容和设置
• 删除Xcode和

  ~/Library/Developer

我真的不知道下一步该怎么做，我能找到的关于这个具体错误的唯一参考资料是在一些中国可可板上，我真的迷路了

---

当我试图打开Xcode时，它也会导致Xcode崩溃。除了完全重新安装Xcode并期待最好的结果外，还有什么解决方案吗？

您可以重置模拟器来修复此错误

sudo gem安装-n/usr/local/bin快照

快照重置\u模拟器

snapshot reset\u模拟器

这似乎就是关键！虽然snapshot会自动执行该过程，但它所采取的确切操作仍位于中。这似乎可以做到这一点！虽然snapshot会自动执行该过程，但它执行的确切操作位于中。
