本文实例讲述了Python模块的制作方法。分享给大家供大家参考，具体如下：

1 目的

利用setup.py将框架安装到python环境中，作为第三方模块来调用，

2 第一步：完成setup.py的编写

以下代码相当于一个模板，只用更改name字段出，改为对应的需要安装的模块名称就可以，比如这里是：py_plus

将setup.py文件放到py_plus的同级目录下

from os.path import dirname, join
# from pip.req import parse_requirements
from setuptools import (
  find_packages,
  setup,
)
def parse_requirements(filename):
  """ load requirements from a pip requirements file """
  lineiter = (line.strip() for line in open(filename))
  return [line for line in lineiter if line and not line.startswith("#")]
with open(join(dirname(__file__), './VERSION.txt'), 'rb') as f:
  version = f.read().decode('ascii').strip()
setup(
  name='py-plus', # 模块名称
  version=version,
  description='A mini web framework', # 描述
  packages=find_packages(exclude=[]),
  author='xx',
  author_email='your@email.com',
  license='Apache License v2',
  package_data={'': ['*.*']},
  url='#',
  install_requires=parse_requirements("requirements.txt"), # 所需的运行环境
  zip_safe=False,
  classifiers=[
    'Programming Language :: Python',
    'Operating System :: Microsoft :: Windows',
    'Operating System :: Unix',
    'Programming Language :: Python :: 2.7',
    'Programming Language :: Python :: 3.4',
    'Programming Language :: Python :: 3.5',
    'Programming Language :: Python :: 3.6',
  ],
)

注意：上面代码中可能会报错需要额外安装packaging模块，更新setuptools

pip install packaging
pip install --upgrade setuptools

pip.req可能不存在，对应的可以：

def parse_requirements(filename):
  """ load requirements from a pip requirements file """
  lineiter = (line.strip() for line in open(filename))
  return [line for line in lineiter if line and not line.startswith("#")]

3 第二步：完成requirements.txt的编写
