规避方案如下： 找到工程目录下configuration–>build-profile.json5文件中的"modules"–>“srcPath"属性，然后按住Ctrl键，鼠标左键点击"srcPath"属性，进入到ohos-project-build-profile-schema.json文件中，将其中"properties”–>"srcPath"属性括号中的正则校验删掉，修改如下 将 “type”: “string”, “pattern”: “^(\./|\.\.//)[\s\S]+$” 改为 “type”: “string”
但是，又有新的错误
/Applications/DevEco-Studio.app/Contents/tools/node/bin/node /Applications/DevEco-Studio.app/Contents/tools/hvigor/bin/hvigorw.js --sync -p product=default --analyze=normal --parallel --incremental --daemon

可以对照这个 PR 修改一下: https://gitee.com/openharmony-sig/flutter_flutter/pulls/275/files 然后删除 flutter_flutter/bin/cache 目录里的 flutter_tools.snapshot 和 flutter_tools.stamp 文件
5.0.3.500 编译flutter应用报错问题-规避方案：
1. 不校验路径的修改
- 使用DevEco-Studio打开以下文件 /Applications/DevEco-Studio.app/Contents/tools/hvigor/hvigor-ohos-plugin/res/schemas/ohos-project-build-profile-schema.json
- 删除校验 srcPath 的正则表达式和上一行末尾的逗号
// ...
”srcPath“: {
// ...
"type": "string"
// 删除这行配置
// "pattern": "^[\\da-zA-Z_-]+$"
}
// ...
2. 不抛出异常的修改
- 使用DevEco-Studio打开以下文件 /Applications/DevEco-Studio.app/Contents/tools/hvigor/hvigor-ohos-plugin/src/model/module/core-module-model-impl.js
- 格式化这个文件
- 修改方法 findBelongProjectPath(e)
// ...
findBelongProjectPath(e) {
if (e === path_1.default.dirname(e)) {
// throw Error(`Cannot find belonging project path for module at ${e}`);
return this.parentProject.getProjectDir();
}
// ...
}
在Flutter开发HarmonyOS鸿蒙Next应用时遇到build报错问题，通常可以从以下几个方面进行排查和解决：
-
检查Flutter和Dart版本：确保你的Flutter和Dart版本与HarmonyOS开发环境兼容。可以在Flutter官网查看最新的版本信息和兼容性说明。
-
依赖项问题：检查
pubspec.yaml文件中的依赖项是否完整且版本正确。运行flutter pub get确保所有依赖项都已正确下载。 -
环境配置：确认你的开发环境（如IDE、SDK等）已正确配置，特别是鸿蒙OS的SDK路径和版本。
-
编译配置：检查
build.gradle或其他相关配置文件，确保编译选项和目标平台设置正确。 -
清理和重建：尝试运行
flutter clean后重新构建项目，这可以解决一些缓存导致的问题。 -
查看错误日志：详细查看编译过程中的错误输出，找出具体的错误信息和可能的解决方案。
-
代码问题：检查代码中是否有特定于鸿蒙OS的API使用不当或不支持的情况。
