Anaconda/Conda创建环境时报错的解决方案

按照Conda网站上的提示安装完Conda之后，想要用conda create创建环境，一直报错：

ERROR conda.core.link:_execute_actions(337): An error occurred while installing package 'defaults::dbus-1.10.10-0'.
PermissionError(13, 'Permission denied')
Attempting to roll back.


PermissionError(13, 'Permission denied')

看样子是安装软件包的权限问题。但问题是安装Conda的时候，并没有使用sudo或切换到root下安装，而是直接使用当前用户安装，最后Conda也是被安装在当前用户的目录下。所以感觉不应该是权限的问题。

但事实就是权限的问题。

我们用ls -l ~/会发现：

.
.
drwxr-xr-x 20 root root 4096 Jun  6 10:22 anaconda3
.
.

用户目录下_anaconda3_文件夹的owner是root，而不是当前用户！实在是非常奇怪。目前我还不知道为什么会这样，但是解决方法就很容易了：

sudo chown -R <USER> anaconda3

这时候再用conda create，就不会报错了，可以顺利创建环境。

When I use Conda to create new environment, it displayed:

ERROR conda.core.link:_execute_actions(337): An error occurred while installing package 'defaults::dbus-1.10.10-0'.
PermissionError(13, 'Permission denied')
Attempting to roll back.


PermissionError(13, 'Permission denied')

I finally found that this was because the USER did not have the permission to access the installed Anaconda directory. When I typed ls -l ~/, I found:

drwxr-xr-x 20 root root 4096 Jun  6 10:22 anaconda3

which was very strange. The owner of anaconda3 is root instead of USER, though I did not use root to install Anaconda. So I sudo chown -R <USER> anaconda3. Solved. Now I can use conda create to create new environment.
