Conda更新权限错误

Question

Python新手在这里。我遇到anaconda的许可问题。一切运行正常，但我似乎无法更新conda，创建新的环境或安装新的软件包。

当我尝试更新（conda update conda）我得到它：

抓取包元数据.....发生意外错误。 请考虑在发布了以下信息 畅达GitHub的问题跟踪：

我得到相同尝试时出错g安装seaborn或创建环境。我不愿意使用sudo因为我不想破坏东西。

我不明白这里发生了什么，所以任何帮助将不胜感激。

非常感谢; T

Answer 1

您应该使用sudo为了写入某些文件到系统中。这非常好，不会破坏你的操作系统，除非你使用复杂和基本的软件包和安装程序（conda和python库非常好）。

sudo conda update conda不仅需要更新conda，还需要安装其他依赖项和软件包。

简而言之，安装程序会尝试将文件写入到它无法访问的特定目录（或修改目录中的文件）。与sudo你让他们这样做，因为你运行与附加priviliges。

Answer 2

您用于运行conda update conda的用户没有/anaconda/pkgs/cache/的写入权限。

如果你不想管理蟒蛇作为超级用户，我建议你创建一个新的用户组（即anaconda_admin）并运行：

sudo groupadd anaconda_admin 
sudo chown -R :anaconda_admin /anaconda 

然后，你将需要确保权限是这样的：

sudo chmod -R 775 /anaconda 

最后，你的用户是anaconda_admin组：
