在终端“ tns Preview”命令中不起作用 NativeScript

如何解决在终端“ tns Preview”命令中不起作用 NativeScript

我想在本地运行NS应用程序。我从play.nativescript.org下载了项目，并用目标路径打开了cmd，然后按照以下步骤操作

步骤1.安装最新的NativeScript CLI

在命令提示符或终端中键入以下命令。

npm install -g nativescript@latest

并且我已经成功安装了NativeScript CLI

第2步。预览您的应用

导航到您的项目文件夹并运行以下命令以启动预览您的应用。

tns preview

输入命令时出现此错误

解决方法

就像github.com中的 therosko 所写的那样，使kinvey-nativescript-sdk的版本为5.0.1对我有用。 Src：enter link description here

不幸的是，play.nativescript.org导出的项目无法在nativescript版本7和更高版本上运行。

当前，唯一的解决方案是使用npm install -g nativescript@6.8.0

安装{N} CLI
