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

>>> 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：

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/

为什么我不能进口？在

Answer 1

我认为您必须单独包含版本化模块，因为您没有包。我不认为find_包方法会找到solo模块。在

尝试将py_modules=['versioned']添加到安装程序中，如下所示：

setup(
    name='peewee-versioned',
    version='0.1.1',
    packages=find_packages(exclude=['test', 'test.*']),
    include_package_data=True,
    platforms='any',
    install_requires=[
        'peewee',
        'six'
    ],
    py_modules = ['versioned']
)

在此之后，您应该能够导入版本化的。在

Answer 2

如果只需要名称，可以使用“import as”功能：

import versioned as peewee_versioned

Answer 3

由于存储库中没有任何包，只有一个名为versioned.py的文件，因此在运行python setup.py install之后，您应该能够将其作为import versioned导入。为我工作：

$ mkvirtualenv peewee
New python executable in peewee/bin/python
...
$ git clone https://github.com/kramer65/peewee-versioned
Cloning into 'peewee-versioned'...
remote: Counting objects: 20, done.
remote: Compressing objects: 100% (12/12), done.
remote: Total 20 (delta 5), reused 18 (delta 5), pack-reused 0
Unpacking objects: 100% (20/20), done.
Checking connectivity... done.
$ cd peewee-versioned/
$ python setup.py install
running install
...
Finished processing dependencies for peewee-versioned==0.1
$ pip freeze
peewee==2.8.0
peewee-versioned==0.1
six==1.10.0
wheel==0.24.0
$ python
Python 2.7.10 (default, Oct 23 2015, 19:19:21)

>>> import versioned

总之，既然您希望它从peewee_versioned导入，我将在这里做两件事：

• 将versioned.py重命名为peewee_versioned.py

• 遵循Listing individual modules文档段落，使用py_modules：
