javascript - Nativescript ios - 命令 xcodebuild 失败，退出代码为空

Question

我通过运行以下命令设置了一个新的 nativescript 应用程序：-

tns create application --ng

当我尝试使用以下方式启动应用程序时：-

tns run ios --emulator

我收到以下错误：-

Unable to apply changes on device: BC7714A3-A8B0-4CEC-A7A4-D54563CF04EE. Error is: Command xcodebuild failed with exit code null.

Executing after-watch hook from /XXXXXX/Desktop/Bike/hooks/after-watch/nativescript-dev-typescript.js

该应用程序偶尔会在没有问题的情况下启动，但在我收到上述错误的 95% 的情况下会停止。

任何帮助将不胜感激。

如果其他人遇到此问题，您需要运行：-

tns platform remove ios; tns platform add ios

在您的终端中，这将解决问题。
