ENTHOUND python包导入优先级

我正在使用venv从PyPI安装一个更新版本的

elpy

软件包，该软件包在根环境中可用。从

pip

查询，我看到了

elpy

的以下版本：

~/python/standalone $ pip show elpy
---
Name: elpy
Version: 1.4.2
Location: /home/wdkrnls/python/env/local/lib/python2.7/site-packages
Requires: flake8

但是，使用解释器可以得到根环境版本

In [4]: import elpy
In [5]: elpy.__version__
Out[5]: '1.3.0'
In [6]: ?elpy
Type:       module
String Form:<module 'elpy' from '/home/ipython/Enthought2/lib/python2.7/site-packages/elpy/__init__.pyc'>
File:       /home/ipython/Enthought/lib/python2.7/site-packages/elpy/__init__.py
Docstring:
The Emacs Lisp Python Environment.

我应该如何维护

sys.path

？我需要所有这些.egg文件来进行树冠分布吗？

看起来您正在使用ipython。如果您尚未在virtualenv中安装ipython，则正在运行的ipython可执行文件将是system one

---

要进行检查，请将

哪个ipython

与

哪个python

进行比较。Python可执行文件应该是virtualenv中的可执行文件。如果打赌ipython可执行文件是系统文件。

可以通过打印

sys.path

Hmm的可能副本来找到优先顺序。。。在检查我的本地包之前，先检查根站点包。导出您的路径。bashrc“/home/wdknrls/python/env/local/bin/ipython”是我安装ipython的位置，与“/home/wdkrnls/python/env/local/bin/python”相比，它是

的。两者似乎都是本地的。@wdkrnls-好吧，那就别管了！当您创建virtualenv时是否使用了
--无站点软件包
选项？我想我告诉过它从站点软件包继承，因为如果我没有在本地安装自己的首选版本，我会使用一些站点软件包。是的，优先级是错误的。最干净的修复方法是什么？sys.path是什么？环境变量PYTHONPATH和PYTHONHOME的值是什么？PYTHONPATH:/home/wdkrnls/python/packages:/home/wdkrnls/python/standalone中只有两个目录。PYTHONHOME中没有任何东西。你的系统路径是什么？我在问题中添加了
sys.path
。它真的很乱，但我不知道如何正确维护它。有什么建议吗？
