Python模块制作与发布

Python模块制作与发布

如果希望自己开发的模块，分享 给其他人，可以按照以下步骤操作

目录结构：

.
|-- hello
|   |-- __init__.py
|   |-- request.py
|   `-- response.py
`-- setup.py

• request.py文件

def hello():
    print("请求调用我")

• response.py文件

from hello.request import hello

def res():
    hello()
    print("已经响应了")

def main():  # 测试
    res()

if __name__ == '__main__':
    main()

• __init__.py文件

from . import request
from . import response

注：这里使用的是Python3.x的解释器。

1. 制作发布压缩包步骤

1) 创建 setup.py

• setup.py 的文件

from distutils.core import setup

# 多值的字典参数，setup是一个函数
setup(name="Hello",  # 包名
      version="1.0",  # 版本
      description="a simple example",  # 描述信息
      long_description="简单的模块发布例子",  # 完整描述信息
      author="onefine",  # 作者
      author_email="[email protected]",  # 作者邮箱
      url="www.onefine.top",  # 主页
      py_modules=["hello.request",
                  "hello.response"])  # 记录包中包中包含的所有模块

有关字典参数的详细信息，可以参阅官方网站：https://docs.python.org/2/distutils/apiref.html

2) 构建模块

构建模块命令如下

$ python3 setup.py build

如果出现下面情况

[email protected]:~/PycharmProjects/Distutils$ python3 setup.py build
Traceback (most recent call last):
  File "setup.py", line 1, in <module>
    from distutils.core import setup
ModuleNotFoundError: No module named 'distutils.core'

同样，安装ipython3

[email protected]:/usr/local/lib/python3.6/dist-packages$ ipython3

Command 'ipython3' not found, but can be installed with:

sudo apt install ipython3

[email protected]:/usr/local/lib/python3.6/dist-packages$ sudo apt install ipython3

因为ubuntu-18.10 默认没有安装 pip ，需要安装 python3-pip

[email protected]:~/PycharmProjects/Distutils$ sudo apt-get install python3-pip
[sudo] onefine 的密码：

输入密码，耐心等待安装之后重新构建模块：

[email protected]:~/PycharmProjects/Distutils$ python3 setup.py build
running build
running build_py
creating build
creating build/lib
creating build/lib/hello
copying hello/__init__.py -> build/lib/hello
copying hello/request.py -> build/lib/hello
copying hello/response.py -> build/lib/hello
[email protected]:~/PycharmProjects/Distutils$ 

3) 生成发布压缩包

生成发布压缩包命令如下

$ python3 setup.py sdist

执行如下

[email protected]:~/PycharmProjects/Distutils$ python3 setup.py sdist
running sdist
running check
warning: sdist: manifest template 'MANIFEST.in' does not exist (using default file list)

warning: sdist: standard file not found: should have one of README, README.txt

writing manifest file 'MANIFEST'
creating Hello-1.0
creating Hello-1.0/hello
making hard links in Hello-1.0...
hard linking setup.py -> Hello-1.0
hard linking hello/__init__.py -> Hello-1.0/hello
hard linking hello/request.py -> Hello-1.0/hello
hard linking hello/response.py -> Hello-1.0/hello
creating dist
Creating tar archive
removing 'Hello-1.0' (and everything under it)
[email protected]:~/PycharmProjects/Distutils$ 

注意：要制作哪个版本的模块，就使用哪个版本的解释器执行！这里使用的是Python3.x。

查看一下

[email protected]:~/PycharmProjects/Distutils$ ls dist -a -l
总用量 12
drwxr-xr-x 2 onefine onefine 4096 1月  14 20:02 .
drwxrwxr-x 7 onefine onefine 4096 1月  14 20:02 ..
-rw-r--r-- 1 onefine onefine  936 1月  14 20:02 Hello-1.0.tar.gz
[email protected]:~/PycharmProjects/Distutils$ 

Hello-1.0.tar.gz就是发布的模块，自己开发的模块制作完成。

3. 安装模块

卸载模块
直接从安装目录下，把安装模块的 目录 删除就可以

至此，模块安装从入门到卸载完成。

4. 使用 pip 安装第三方模块

第三方模块 通常是指由 知名的第三方团队 开发的 并且被 程序员广泛使用 的 Python 包 / 模块,例如 pygame 就是一套非常成熟的 游戏开发模块

• pip 是一个现代的，通用的 Python 包管理工具
• 提供了对 Python 包的查找、下载、安装、卸载等功能

安装和卸载命令如下：

# 将模块安装到 Python 2.x 环境
$ sudo pip install pygame
$ sudo pip uninstall pygame

# 将模块安装到 Python 3.x 环境
$ sudo pip3 install pygame
$ sudo pip3 uninstall pygame

在 Mac 下安装 iPython

$ sudo pip install ipython

在 Linux 下安装 iPython

$ sudo apt install ipython
$ sudo apt install ipython3
