可能出现的问题

在HarmonyOS DevEco Studio下出现SDK无法下载js的情况,该如何解决?

问题描述:

根据HarmonyOS官方文档集成IDE成功后,下载SDK时遇到无法下载js,提示npm(node)安装失败等信息:

Error: : Install failed.  Error: : Install js dependencies failed. Unable to run 'npm install'. Js install ation failed. See https://developer.harmonyos.com/cn/docs/documentation/doc-guid es/environment_config-0000001052902427#ZH-CN_TOPIC_0000001154865731

注:安装js依赖项失败,无法运行“npm install”,Js安装失败。 

解决方法

1.安装nodejs,官网下载:https://nodejs.org/zh-cn/download/

2.将DevEco Studio 自带的node替换为本地安装的node(自己从官网下载的nodejs),进入IDE软件,打开Setting(file---->setting),设置如下图:

3.在设置的快速搜索框内输入node,修改DevEco Studio自带的node,修改为自己下载的nodejs安装位置,如下图:

4.修改完成就可以下载SDK的js,输入SDK,勾选js,然后点击apply下载!

DevEco Studio allows you to debug your app written in multiple languages. In a JS project or C/C++ project, you can select the Java+JS or Java+C debug type. Before debugging a hybrid project, set the debug type to Dual(Js + Java) or Detect Automatically. For a C/C++ project, set the debug type to Dual(Java + Native) or Detect Automatically.
DevEco Studio允许您调试用多种语言编写的应用程序。在JS项目或C/C++项目中,可以选择Java+JS或Java+C调试类型。调试混合项目之前,请将调试类型设置为Dual(Js+Java)或自动检测。对于C/C++项目,将调试类型设置为Dual(Java+Native)或自动检测。
Enable or disable JS postfix code completion from Settings > Editor > General > Postfix Templates. The following figure shows the supported types of postfix code completion.
从设置>编辑器>常规>后缀模板启用或禁用JS后缀代码完成。下图显示了支持的后缀代码完成类型。
If a device in a project has multiple modules and the modules are invoked by each other, you need to install the .hap packages of multiple modules on the device in the debug phase. In this case, select Deploy Multi Hap Package in the settings of the module to be debugged.
如果项目中的一个设备具有多个模块,并且这些模块相互调用,则需要在调试阶段在该设备上安装多个模块的.hap包。在这种情况下,请在要调试的模块的设置中选择Deploy Multi-Hap Package。
DevEco Studio supports Java code obfuscation. You can manually set proguardEnabled in the build.gradle file of the module to true to enable the function.
devecostudio支持Java代码模糊处理。您可以在模块的build.gradle文件中将proguardEnabled手动设置为true以启用该功能。
When compiling code, you can use the previewer to view the UI layout. The XML, Java, JS, CSS, and HML files can be previewed. You can open the previewer in any of the following ways:
