当我运行

tns运行android时

由于某些原因，它无法启动模拟器并运行应用程序。我遗漏了什么？

此链接有帮助。我可以执行tns运行android，它会在模拟器上加载应用程序

tns run ios启动ios模拟器，但不加载应用程序。。。。。这就是我在终端中看到的：tns run ios——强制您使用不推荐的nsconfig.json文件。请注意，NativeScript 7有一个改进的NativeScript.config.（js | ts）文件，可用于升级此项目。下一版本的NativeScript将不支持当前的Xcode版本10.0.0。考虑更新XCODE到最新官方版本。正在搜索设备。。。找不到执行操作的适用设备。请确保连接的设备受信任，然后重试。tns run ios会启动ios模拟器，但不会加载应用。。。。。这就是我在终端中看到的：tns run ios——强制您使用不推荐的nsconfig.json文件。请注意，NativeScript 7有一个改进的NativeScript.config.（js | ts）文件，可用于升级此项目。下一版本的NativeScript将不支持当前的Xcode版本10.0.0。考虑更新XCODE到最新官方版本。正在搜索设备。。。找不到执行操作的适用设备。请确保连接的设备受信任，然后重试。
