Question

在我的第一个android构建之后，我遇到了这个问题；然后，在此之前，项目将在设备甚至仿真器中进行开发。错误也会在模拟器中发生。

我一直在研究。更新到NativeScript tns-android: 5.4.0 tns-core-modules: 5.4.3 nativescript-vue: 2.2.2的当前最新版本，还更新Firebase插件nativescript-plugin-firebase: 9.0.1。这不允许我继续该项目。此刻我对此感到非常沮丧。

Unable to apply changes on device: DEVICE####. 
Error is: Cannot read property 'env' of undefined.

使用--log trace显示

在此先感谢您的帮助，这完全阻碍了项目的发展。

如果您尝试将nativescript-dev-webpack @ next与NativeScript CLI的最新正式版本（5.4.2）一起使用，则将出现此错误，因为它们彼此之间不兼容（为NativeScript 6.0版本做准备）。

如果您想使用nativescript-dev-webpack @ next，则还需要安装nativescript @ next。

希望这会有所帮助！

无法在设备“ DEVICE ####”上应用更改。错误是：无法读取未定义的属性“ env”
