如何使用Flutter框架推流_音视频终端 SDK(Apsara Video SDK)-阿里云帮助中心MediaBox音视频SDK下载指南_音视频终端 SDK(Apsara Video SDK)-阿里云帮助中心 终端输入 dart pub --trace get --no-precompile 打印详细报错信息 详细咨询chatgpt pub.dev 中已经是最新版本了 项目中已经是最新版本了 最终定位到 终端输出dart版本是 电脑环境变量中的版本 和阿里云咨询的版本不匹配 您好 ,用我们的推荐版本吧 $ flutter --version Flutter 2.8.0 • channel unknown • unknown source Framework • revision cf44000065 (1 年 4 个月前) • 2021-12-08 14:06:50 -0800 Engine • revision 40a99c5951 Tools • Dart 2.15.0 尝试解决方案电脑中重新设置环境变量
新配置flutter 2.8的环境变量 上移动到最上面 三步确定保存环境变量
更改后重启IntelliJ IDEA 2023.3.6 使环境变量生效
这样环境变量就对上了 运行
dart pub --trace get --no-precompile
提示如下 运行
dart pub --trace pub --trace get --no-precompile Windows 新增两个环境变量 PUB_HOSTED_URL https://mirror.sjtu.edu.cn/dart-pub
FLUTTER_STORAGE_BASE_URL https://mirror.sjtu.edu.cn
替换为如下
PUB_HOSTED_URL https://pub.flutter-io.cn
FLUTTER_STORAGE_BASE_URL https://storage.flutter-io.cn注意测试你的电脑要连上手机的数据流量进行下载依赖
执行 pub get 报错信息如下 报错信息翻译如下 遇到了新的报错信息 缺少这个包 pub.dev 搜索到安装 翻译如下 因为flatter_livepush_demo依赖于flatter_gen5.3.0 调整 flatter_gen版本为小于5.3 Running flutter pub get in ceshi... The current Dart SDK version is 2.15.0. Because flutter_livepush_demo depends on flutter_gen 5.3.0 which requires SDK version 2.17.0 4.0.0, version solving failed. pub get failed (1; Because flutter_livepush_demo depends on flutter_gen 5.3.0 which requires SDK version 2.17.0 4.0.0, version solving failed.) 这个报错是什么呢 怎么解决 这个报错是因为你的项目中使用了一个依赖flutter_gen要求Dart SDK版本必须在2.17.0及以上但小于4.0.0而你当前的Dart SDK版本是2.15.0所以版本解析失败导致报错。 要解决这个问题你可以尝试升级你的Dart SDK版本到符合要求的版本2.17.0 4.0.0。你可以通过运行flutter upgrade来升级Flutter SDK这可能会同时升级Dart SDK版本。然后再次运行flutter pub get看看是否问题解决了。 如果升级SDK版本后问题仍然存在你可以尝试联系依赖库的开发者看是否可以更新他们的依赖要求或者尝试使用其他版本兼容的依赖。 这个报错是因为你的项目中使用了一个依赖flutter_gen要求Dart SDK版本必须在2.17.0及以上但小于4.0.0而你当前的Dart SDK版本是2.15.0所以版本解析失败导致报错。
解决方案 新增
flutter_gen: ^5.3.0 依赖 再次下载 flutter sdk 使用其中的 dart 版本 2.17.0 就没有这个报错了

该问题由 Gradle 的Maven仓库在国外访问受限引起使用阿里云的镜像仓库地址替代解决
1.修改Flutte SDK目录下的Flutter打包配置文件flutter.gradle
一般位于flutter\packages\flutter_tools\gradle\flutter.gradle https://www.cnblogs.com/fanqisoft/p/17528904.html 运行后出问题 算了 还是明天问阿里的工作人员把
问题 今天我有又来了
您好这个问题白天找后端看下有进展反馈您 售后工程师

您好 ,Gradle 版本与Java JDK版本不兼容, 这种问题网上找一下解决方案 参天果树啊
2024-04-12 11:36
你那边的 java jdk版本是要求多少 项目也要换
将电脑环境变量中的 java jdk版本11.0.22 换成16.0.2
C:\Users\Administrator\.jdks\corretto-11.0.22
C:\Users\Administrator\.jdks\corretto-16.0.2 三步确定 后记得重启 开发工具 使开发环境生效
遇到新的问题 解决方案参考
