自己的pip python包导入不起作用

我目前正在尝试创建我的第一个python包。可悲的是,我遇到了一些错误。我只想尝试定义一些应该可导入的类。

继承我的文件夹结构

/pip-blitz-query
    /blitzjs_query
        __init__.py
        blitz.py
        blitz_http.py
        ...
    setup.py

当我尝试从Blitz导入类blitzjs_query时发生的错误:

>>> import blitzjs_query
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python34\lib\site-packages\blitzjs_query\__init__.py", line 1, in <module>
    from blitz import Blitz
ImportError: No module named 'blitz'

继承我的__init__.py文件:

from blitz import Blitz
from connection import Connection
from blitz_queue import Queue
from blitz_socket import Socket
from blitz_http import Http

最后这是我的setup.py文件。我尝试了__init__.py文件的不同版本,有些文章根本没有任何内容 - 但它只是从不起作用

# Always prefer setuptools over distutils
from setuptools import setup, find_packages
# To use a consistent encoding
from codecs import open
from os import path

# Get the long description from the README file
here = path.abspath(path.dirname(__file__))
with open(path.join(here, 'README.rst'), encoding='utf-8') as f:
    long_description = f.read()

setup(
    name='blitzjs_query',

    version='0.0.2',

    description='HTTP/Socket.io adapter for the blitz.js framework',
    long_description=long_description,

    url='https://github.com/nexus-devs/pip-blitz-query',

通常你使用相对导入(在子模块前加上一个或多个.):

from .blitz import Blitz
from .connection import Connection
from .blitz_queue import Queue
from .blitz_socket import Socket
from .blitz_http import Http

因为您不创建名为blitz的模块,而只创建模块blitzjs_query.blitz

有关相对和绝对导入的更多信息,请参阅PEP 328

  

Guido已发表相关进口将使用领先点。单个前导点表示相对导入,从当前包开始。两个或多个前导点为当前包的父级提供相对导入,在第一个之后每个点一个级别。 [...]

您的模块名为blitzjs_query,因此请将所有导入作为blitzjs_query.

的前缀

像这样:

from blitzjs_query.blitz import Blitz
from blitzjs_query.connection import Connection
from blitzjs_query.blitz_queue import Queue
from blitzjs_query.blitz_socket import Socket
from blitzjs_query.blitz_http import Http
