antd v3 升级 v4

Posted 2023-04-08

参考技术A antd v4 使用hook对组件进行了升级，react项目使用hook的话升级v4会比较好。

antd V4 提供了一个 codemod cli 工具 @ant-design/codemod-v4 以帮助快速升级到 v4 版本。
废弃的组件则通过 @ant-design/compatible 保持运行（从 @ant-design/compatible 引入的老版本 Form 组件，样式类名会从 .ant-form 变成 .ant-legacy-form）如果进行了样式覆盖，需要进行调整。

通过 npx 直接运行
npx -p @ant-design/codemod-v4 antd4-codemod src

或者全局安装
使用 npm
npm i -g @ant-design/codemod-v4
或者使用 yarn
yarn global add @ant-design/codemod-v4

antd4-codemod src
以上升级完成

需要注意组件配色问题，如进行了样式覆盖需要对应处理。

升级到 V 2.0.3 后 Flutter Build 失败

【中文标题】升级到 V 2.0.3 后 Flutter Build 失败

【问题描述】：

将我的 Flutter 升级到 V2，尝试让默认应用在我的 Android 设备上运行！不走运！

到目前为止我做了什么：

从测试版切换到稳定版 再次运行颤振升级 得到颤振医生[一切都很好] 尝试运行 [失败，多次] 试过flutter clean 清除了 gradle 缓存，没有运气 再次尝试构建，失败

如果有任何帮助，我将不胜感激，这已经占用了我很多时间。

【问题讨论】：

嘿，你能发布你的 android/app/build.gradle 文件吗？

嗨@xerib，感谢您的回复，用 build.gradle 文件更新了问题

【参考方案1】：

你可以试试

退出 IDE 移动或删除 ~/.android/debug.keystore 和 ~/.android/debug.keystore.lock 文件 使用flutter clean 方法 重新编译您的应用程序

【讨论】：

伙计，谢谢！有效。我的感激之情。

对我有任何帮助。 2.0 升级后，寻找与 Flutter Web 版本类似的问题失败。通过以下链接发布的问题。 ***.com/questions/67000431/…
