报错信息
有一天准备用conda配置新的环境，结果conda突然各种报错，怎么都装不了。（我conda环境装在了 `D:\Software\Anaconda`）

百思不得其解。这里提供两个可能有用的网址。

最终的解决方案
遵循上面的第一个链接的提示以及我最近配置vscode的情况，主要是通过以下几个步骤解决。
- 由于我之前vscode也安装了新的python，默认路径在user/Appdata下，我当时还为其设置了环境path。首先我们要讲这个路径的环境path删除，要不然这会导致在conda中的pip install指令全部都默认装到该python的site-packages目录下。默认是在AppData/Roaming/Python/下。
- 安装pywin32包，我按照第一个链接的指示，安装了 pip install pywin32=300，顺带装了个pip install pathli
装完之后就突然可以了，有点小神奇。
结论：捣鼓其他东西的时候记得不要乱给权限。
