python与linux关系_如何处理Linux / Python依赖关系？

由于缺乏对我想使用的一些库的支持,我将一些

Python开发从Windows转移到Linux开发.我已经花了大部分时间搞乱了依赖关系.

问题

每当我拿起Linux,我通常会遇到一些依赖问题,通常是开发库,无论是通过apt-get,easy_install或pip安装.我可以浪费时间,应该是简单的任务,花更长的时间让图书馆工作,而不是编写代码.在哪里可以了解处理这些问题的策略,而不是为了遇到同样问题的人而无缘无尽地搜索？

一个例子

所以,我发现在pypi的包,并认为使用这将使生活更轻松：

(我可能通过使用virtualenv来保持整洁,让自己的生活变得更加困难.)

Cleaning up...

(我想我可能sudo apt-get安装libqrencode-dev之前的某个时间点.)

所以我试图运行测试脚本：

(myenv3)mat@ubuntu:~/myenv3$python test_qr.py

Traceback (most recent call last):

File "test_qr.py", line 1, in

from qrencode import Encoder

File "qrencode.pyx", line 1, in init qrencode (qrencode.c:1520)

ImportError: No module named ImageOps

🙁

那么,investigations透露,ImageOps似乎是PIL的一部分…

嗯,PIL的安装,但没有拿起我安装的库sudo apt-get install libjpeg62 libjpeg62-dev libpng12-dev zlib1g zlib1g-dev之前.我不知道如何告诉pip将库位置提供给setup.py. Googling建议我尝试过各种各样的ideas,但是似乎没有一个可以帮助我,而不是把我送回来.
