python：easy_install 期间会发生什么？

我对 Egg 文件和使用 easy_install 安装它们有点困惑，希望你能帮助我。（我读到了人们对 pip 的推荐，但在继续之前我想了解这一点）。

如果我只是从拇指驱动器复制例如 django_guardian-1.0.2-py2.6.egg 并将其放置在 PYTHONPATH 指向的例如 ~/bar/ 中，尝试通过 import Guardian 导入内容会产生 importError。即使我现在复制了 easy_install.pth 也会出现此错误

import sys; sys.__plen = len(sys.path)
./django_guardian-1.0.2-py2.6.egg
import sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:]; p=getattr(sys
'__egginsert',0); sys.path[p:p]=new; sys.__egginsert = p+len(new)

，使用 easy_install django-guardian 当然没有这样的问题。

我导航到了 egg 文件 easy_installed 所在的目录，它包含的只是 .pth 和 .egg 文件。我想知道 easy_install 在某个地方做了哪些其他过程/条目，导致第一种方法无法使用......

I'm a little confused about egg files and installing them using easy_install, hope you can help me with it. (I read about people's recommendation on pip, but I'll like to understand this before I move on).

If I simply copy e,g django_guardian-1.0.2-py2.6.egg from say, a thumbdrive and place in e.g ~/bar/ which PYTHONPATH was pointing to, trying to import the contents via import guardian would yield me importError. This error occur even if I have the easy_install.pth copied in

import sys; sys.__plen = len(sys.path)
./django_guardian-1.0.2-py2.6.egg
import sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:]; p=getattr(sys
'__egginsert',0); sys.path[p:p]=new; sys.__egginsert = p+len(new)

Now, using easy_install django-guardian, of course had no such problem.

I navigated to the directory the egg file was easy_installed to, and all it contains was the .pth and the .egg file. I wish to know what other procedures/entries does easy_install makes somewhere that makes the first method unusable....
