我正在尝试安装 Discord 机器人 cog，但出现错误：

That cog has requirements that I could not install. Check the console for more informations.

所以我检查了控制台。这就是发生的事情。

我知道这是权限方面的一些错误，但我不确定该怎么做。有人能帮我吗？提前致谢！ [我不太了解命令提示符或文件夹权限，因此提供命令会很好:)] 再次提前感谢 - 一个刚刚起步的程序员

【问题讨论】：

编辑那个文件夹的权限，或者使用cmd作为管理员试试
老实说，我真的不知道该怎么做。
不过，我会尝试我知道的方法。编辑：它没有工作。我只知道takeown / f。它说“当前登录的用户对文件夹 C:\Users\ 没有所有权权限” [我尝试了 C:\Users 文件夹，因为如果我尝试该文件夹，它会说“无效参数：交叉---#\Documents \Red-DiscordBot\" 我以管理员身份运行它。

【解决方案1】：

我找到了答案。 请执行以下操作： 1.以管理员身份打开命令提示符（在开始菜单中搜索cmd，右键以管理员身份运行） 2. 输入以下内容：takeown /f C:\ 3. 如果操作成功，请关闭命令提示符并转到此 PC。 4. 右键单击 C:\ 驱动器。 5. 单击属性。 6. 单击窗口顶部的安全选项卡。 7. 转到您的用户名并单击编辑。 8. 勾选完全控制框。 9. 保存。 10. 再次运行命令。如果这种情况持续存在，则 takeown 命令可能没有正确执行。
