为什么我不能导入我自己创建的Python包？

Question

我刚刚创建了一个Python包（sources here），但在安装后使用它有问题。一个简单的导入给我一个ImportError。在

下面我将详细展示我所做的，以便您可以复制：

$ git clone git@github.com:kramer65/peewee-versioned.git
Cloning into 'peewee-versioned' 
etc. etc.
Checking connectivity... done.
$ virtualenv venv
New python executable in the/path/to/my/venv/bin/python
Installing setuptools, pip, wheel...done.
$ . venv/bin/activate
(venv) $ cd peewee-versioned/
(venv) $ python setup.py install
running install
etc. etc. everything installs without errors
Finished processing dependencies for peewee-versioned==0.1
(venv) $ cd ..
(venv) $ pip freeze
peewee==2.8.0
peewee-versioned==0.1  # AS YOU CAN SEE IT IS INSTALLED
six==1.10.0
(venv) $ python
Python 2.7.10 (default, Oct 23 2015, 18:05:06)
[GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.59.5)] on darwin

>>> import peewee
>>> import peewee_versioned
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named peewee_versioned

我的设置.py看起来像这样：

^{pr2}$

项目中唯一相关的文件是versioned.py（参见full sources here）

有人知道我做错了什么吗？欢迎所有提示！在

我检查了venv站点包中是否有与我的包相关的鸡蛋，并且有（检查第5个包）：

$ ls -l venv/lib/python2.7/site-packages/

如果只需要名称，可以使用“import as”功能：

import versioned as peewee_versioned
