使用Scoop安装Python失败：dark组件下载出错求助

问题情况 #

执行scoop install python后，系统自动清理之前安装失败的dark组件，但在安装dark 3.11.2版本时，aria2下载对应zip文件触发网络错误导致安装终止，更换网络、关闭防火墙后问题仍未解决。具体报错信息：

scoop install python

解决方案 #

• 禁用aria2多线程下载：
  执行以下命令关闭aria2，改用单线程下载：

  scoop config aria2-enabled false
  

  之后重新运行scoop install python即可。

• 手动下载dark组件到缓存：

  1. 手动下载dark 3.11.2的压缩包（对应报错中的链接）。
  2. 将文件重命名为dark#3.11.2#https_raw.githubusercontent.com_ScoopInstaller_Binary_master_dark_dark-3.11.2.zip，放入Scoop缓存目录（默认路径为D:\scoop\cache）。
  3. 重新执行scoop install python，Scoop会直接使用缓存文件完成安装。

• 重置缓存并更新Scoop：

  1. 清理所有Scoop缓存：

     scoop cache rm *
     

  2. 更新Scoop及所有bucket：

     scoop update
     

  3. 再次尝试安装Python：scoop install python
