-# 常见问题解答
-
-## QQ 音乐
-
-### 解锁失败
-
-#### 1、请检查您的文件。
-
-尝试用下载音乐的设备播放一次看看，如果 QQ 音乐都没法播放，那解锁肯定会受到影响哦。
-
-#### 2、检查您的平台。
-
-日前，<mark>仅 Windows 客户端 v19.43 或以下版本</mark>下载的歌曲无需密钥，其余平台的官方正式版本均需要提取密钥。
-
-> iOS 用户提取歌曲困难，建议换用电脑操作；Android 用户提取密钥需要 root，也建议用电脑操作。
-
-> 重复下载同一首的歌曲**不重复扣下载配额**，但是*同一首歌的两个版本会重复扣下载配额*，请仔细分辨。
-
-提取密钥教程请访问[新版解锁网站](https://um-react.netlify.app/)，前往网站内的设置 →“添加一条密钥”旁的<mark>**下拉按钮**</mark>→ 从文件导入密钥…→ 选择您对应的平台查看具体教程。
-
-> 如果仍无法理解，可参考文末的图片操作
-
-## 酷我音乐
-
-### 解锁失败
-
-酷我音乐的新版加密需要导入密钥。
-
-#### 1、请检查您的文件。
-
-尝试用下载音乐的设备播放一次看看，如果酷我音乐都没法播放，那解锁肯定会受到影响哦。
-
-#### 2、检查您的平台。
-
-日前，<mark>仅手机客户端</mark>下载的歌曲**至臻全景声**及**至臻母带**为新版加密，手机平台的其他音质暂时不需要提取密钥，PC 平台暂未推出使用新版加密的音质。
-
-※ 已知部分第三方修改版会破坏密钥写出功能，导致无法导入密钥。请使用官方版本。
-
-> Android 用户提取密钥需要 root，或者注入文件提供器。
-
-提取密钥教程请访问[新版解锁网站](https://um-react.netlify.app/)，前往网站内的设置 →<mark>切换密钥为 KWMv2 密钥</mark>→“添加一条密钥”旁的<mark>**下拉按钮**</mark>→ 从文件导入密钥…→ 选择您对应的平台查看具体教程。
-
-> 图片教程请参考 QQ 音乐（在文末），酷我音乐仅仅是需要切换一下密钥类型。
-
-## 网易云音乐
-
-### 解锁失败
-
-您大概率正在使用 Windows 平台的网易云音乐 3.0 测试版。该版本对歌曲的信息新增了某些字段，导致旧版解锁识别错误。您可以找 1.10.5 版本的旧解锁网站，或者直接换[新版解锁网站](https://um-react.netlify.app/)。
-
-> [旧解锁网站 Demo](https://demo.unlock-music.dev/)拥有者暂时联系不上，所以暂时无法更新。
-
-## 其他问题
-
-### 新版解锁网站解锁的歌曲没有封面
-
-目前新版没有做歌曲信息匹配与编辑，所以歌曲如果自己没有写入歌曲信息，解出来就是没有的。
-
-### 安卓 root 相关
-
-对安卓设备获取 root 特权通常会破坏系统的完整性并导致部分功能无法使用。
-例如部分厂商的安卓设备会在解锁后丧失保修资格，或导致无法使用 NFC 移动支付功能等限制。
-
-如果希望不破坏系统完整性，你可以考虑使用模拟器。
-
-※ **注意**：根据应用厂商的风控策略，使用模拟器登录的账号**有可能会被封锁**；使用前请自行评估风险。
-
-目前常见的带有 root 特权支持的的安卓模拟器方案，分别是雷电模拟器（※ 官方版有内置广告）和微软在 Windows 11 开始支援的适用于 Android™ 的 Windows 子系统 (WSA)。
-
- WSA 可以参考 [MagiskOnWSALocal](https://github.com/LSPosed/MagiskOnWSALocal) 的说明操作。
- 雷电模拟器可以在「模拟器设置」 → 「其他设置」中启用 root 特权。
-  ![雷电模拟器 其他设置](../src/faq/assets/ld_settings_misc.webp)
-
-### Via 等浏览器无法正常解密/下载
-
-⚠️ 手机端浏览器支持有限，请使用最新版本的 Chrome 或 Firefox 官方浏览器。
-
-已知有问题的浏览器：
-
- Via 浏览器
- 夸克浏览器
- UC 浏览器
-
-可能会遇到的问题包括：
-
- 网页白屏
- 无法下载解密后内容
- 下载的文件名错误
-
-### 新版解锁网站没有批量下载
-
-目前没有做。抱歉。

-# 新手上路
-
-该文档描述了如何本地运行或编译生产版本的「Unlock Music 音乐解锁」。
-
-## 安装依赖
-
- 安装 Node v16.17 或更高，推荐当前最新的 Node LTS 版本。
- 安装/激活 `pnpm` [^1]：`corepack prepare pnpm@latest --activate`
- 安装软件依赖：`pnpm i --frozen-lockfile`
-
-[^1]: 参考 pnpm 说明「[使用 Corepack 安装](https://pnpm.io/zh/installation#使用-corepack-安装)」。
-
-## 本地运行
-
-💡 你需要先完成「安装依赖」部分。
-
-```sh
-pnpm start
-```
-
-然后根据提示打开[项目运行页面][vite-dev-url]即可。
-
-[vite-dev-url]: http://localhost:5173/
-
-## 构建生产版本
-
-💡 你需要先完成「安装依赖」部分。
-
-```sh
-pnpm build
-```
-
-如果需要预览构建版本，运行 `pnpm preview` 然后打开[项目预览页面][vite-preview-url]即可。
-
-[vite-preview-url]: http://localhost:4173/
-
-## 打包 `.zip`
-
-建议在 Linux 环境下执行，可参考 `.drone.yml` CI 文件。
-
-1. 确保上述的构建步骤已完成。
-2. 确保 `python3` 已安装。
-3. 执行下述代码
-   ```sh
-   python3 -m zipfile -c um-react.zip dist/.
-   ```
-
-## 打包 win64 单文件
-
-利用 Windows 系统自带的 [Edge WebView2 组件](https://learn.microsoft.com/zh-cn/microsoft-edge/webview2/)
-和 [wry](https://github.com/tauri-apps/wry) 进行一个单文件的打包。
-
-大部分 Windows 10 或以上版本的操作系统已经集成了 WebView2 运行时。若无法正常启动，请[下载并安装 Edge WebView2 运行时](https://go.microsoft.com/fwlink/p/?LinkId=2124703)。
-
-其它系统兼容性未知。
-
-1. 确保你现在在 `linux-amd64` 环境下。
-2. 确保上述的 `um-react.zip` 构建已完成。
-3. 执行下述代码
-   ```sh
-   ./scripts/make-win64.sh
-   ```
-4. 等待提示 `[Build OK]` 即可。
