Question

尝试在ubuntu 16.04 LTS上安装AROSICS（https://pypi.python.org/pypi/arosics/0.8.2）时。

当我这样做时：

~$ sudo pip install arosics

然后我得到：

The directory '/home/user/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

也尝试过：

sudo -H pip install arosics

我不确定出了什么问题。我尝试了pip install python-util但事件之后我一直收到同样的错误。

请问如何继续？

Answer 1

Arosics目前只适用于Python3。 from importutil import util在Python 2.7下不起作用，因为它不受支持。

如果选择切换到Python3是一个很好的选择。如果没有，则必须修改Arosics项目的setup.py。

我能够使用sudo pip3 install arosics

成功安装

Answer 2

此问题已在0.8.14版的Arosics中修复。现在它应该再次兼容Python 2.7。

但是，选择Python 3！
