在 Flutter VScode 中运行调试 ios 应用程序时出错
Posted
技术标签:
【中文标题】在 Flutter VScode 中运行调试 ios 应用程序时出错【英文标题】：Error running debug ios app in Flutter VScode 【发布时间】：2020-08-24 17:01:38 【问题描述】：我最近在 macos 中安装并设置了 Flutter。我在 Visual Studio 代码中安装了所有颤振 sdk 和插件。但是我在测试应用程序时遇到了错误。我已经打开了 ios 模拟器，然后尝试通过 Flutter run 运行应用程序。但它总是失败并显示以下错误。我已经尝试过 Flutter clean 和 flutter pub get 很多次。仍然没有解决方案。
我在终端中得到的日志输出和错误：

我是 Flutter 的新手，对 Flutter 应用知之甚少。不得不删除一些无用的日志，因为它只允许输入 30000 字。
【问题讨论】：
请参阅Under what circumstances may I add “urgent” or other similar phrases to my question, in order to obtain faster answers? 当您需要紧急帮助时，Stack Overflow 可能不是寻找它的正确位置。在这里回答的都是志愿者，这个问题才发了 4 个小时（想想时区，不是每个用户此时都醒着），而且是周末。请耐心等待。 你是怎么解决这个问题的？我有同样的问题。 @easazade 尝试将 macos caltalina 更新到稳定版本。我认为测试版有这个错误 我的 virtualbox 和 xcode 11.3 上的 Catalina 10.15 beta 也有同样的问题。将更新到 10.15.4 并使用 xcode 12 进行测试 【参考方案1】：尝试将您的 macos 更新到稳定版本。我认为测试版有这个错误。更新对我有用。
