[求助]DevEco Studio编译 OpenHarmony项目报错

[求助]DevEco Studio编译 OpenHarmony项目报错 各位大佬，今天编译默认项目，HarmonyOS下可以编译通过，但是把runtimeOS改成OpenHarmony后就编译报错了。有大佬遇到过吗😭😭😭

DevEco版本：5.1.1
SDK版本： 5.0.0.71(12)
详细报错：

cJSON_Parse failed 表明 rpcid.json 文件解析失败

1.检查 rpcid.json 文件是否存在语法错误（如括号未闭合、引号缺失、逗号错误等）。

2.清理构建缓存

执行以下操作：

删除 entry/build 目录；

在项目根目录运行 hvigor clean 或点击 DevEco Studio 菜单栏的 Build > Clean Project；

重新构建项目。

检查权限配置

确认 module.json5 中 requestPermissions 的 user_grant 类型权限是否包含 reason 和 usedScene 属性（如缺失会间接引发工具链错误）。


楼主删除 entry\build 目录，重新执行编译构建，确保生成的 rpcid.json 无残留错误。检查文件编码是否为 UTF-8 无 BOM 格式。然后调整 Syscap 配置—在 entry/oh-package.json5 中仅保留 OpenHarmony 支持的 Syscap，移除 HarmonyOS 专属能力，比如：

{
  "syscap": [
    "SystemCapability.ArkUI.ArkUI.Full",
    "SystemCapability.ArkUI.ArkUI.Napi",
    "SystemCapability.Base",
    "SystemCapability.BundleManager.BundleFramework"
  ]
}

检查 SDK 工具链，确保 OpenHarmony 工程使用的 SDK 与 DevEco Studio 版本匹配。通过 File > Settings > SDK Manager 确认 OpenHarmony SDK 路径是否正确。

我看了下entry/oh-package.json5这个文件没有 HarmonyOS专属能力，甚至连 syscap标签都没有😭

syscap_tool.exe
看日志用的是 api 12 的， 但是 ide 里面也有这个可执行文件

你可以试着降一下 ide 的版本，例如， 5.0.0

话说回来，这个问题我看的也不是很懂，只是提供一个思路

找HarmonyOS工作还需要会Flutter的哦，有需要Flutter教程的可以学学大地老师的教程，很不错，B站免费学的哦：https://www.bilibili.com/video/BV1S4411E7LY/?p=17

感谢大佬，我降版本试试，

5.1.* 的 ide 默认是 18 的 api， 你这看起来像 12 的 api

12的

对 我要用12的SDK，

DevEco Studio编译OpenHarmony项目报错可能原因：

  1. SDK版本不匹配，检查项目配置的SDK版本是否与设备兼容
  2. 依赖缺失，确认build-profile.json中依赖项配置正确
  3. 资源文件错误，检查resources目录下的文件格式和命名规范
  4. Gradle插件版本冲突，查看项目级build.gradle中的classpath配置
  5. 缓存问题，执行File > Invalidate Caches清除缓存

常见解决方法：

  1. 同步项目配置（Tools > SDK Manager）
  2. 检查oh-package.json中的依赖版本
  3. 确认Node.js和npm版本符合要求
  4. 查看build日志定位具体错误行

从报错信息来看，问题出在syscap_tool.exe解析rpcid.json文件时失败。具体错误是"cJSON_Parse failed"，表明json文件解析异常。

可能的原因：

  1. rpcid.json文件编码格式有问题，建议检查文件是否为UTF-8编码
  2. 文件内容被破坏，可以尝试删除build目录重新编译
  3. SDK工具链版本不匹配，OpenHarmony SDK 12的syscap_tool可能不兼容当前项目配置

建议操作步骤：

  1. 清理项目：删除entry/build目录
  2. 检查rpcid.json文件编码格式，确保是标准UTF-8
  3. 确认使用的OpenHarmony SDK版本与项目要求的版本一致
  4. 如果问题依旧，尝试创建一个全新的OpenHarmony项目测试基础编译功能

错误日志显示解析时出现乱码"坿P7"，这通常表明文件二进制内容已损坏或编码格式异常。
