创建Python本地副本

创建本地副本后可以避免解释器找不到模块的情况。

1. 创建一个测试用的pl.py

def printTest():
    print("this is a test")

2. 将pl.py放入pl文件夹中，并在pl文件夹中再创建一个setup.py

from distutils.core import setup

setup(
    name='pl',
    version ='1.0.0',
    py_modules=['pl'],
    author='htest',
    author_email='htest@gmail.com',
    url='http://www.test.com',
    description='this is a test',
    )

3. 构建发布文件--进入pl目录，并在cmd中输入python setup.py sdist

D:python	estpl>python 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 pl-1.0.0
making hard links in pl-1.0.0...
hard linking pl.py -> pl-1.0.0
hard linking setup.py -> pl-1.0.0
creating dist
creating 'distpl-1.0.0.zip' and adding 'pl-1.0.0' to it
adding 'pl-1.0.0PKG-INFO'
adding 'pl-1.0.0pl.py'
adding 'pl-1.0.0setup.py'
removing 'pl-1.0.0' (and everything under it)

4. 创建本地副本--同样在pl目录，并在cmd中输入python setup.py install

D:python	estpl>python setup.py install
running install
running build
running build_py
creating build
creating buildlib
copying pl.py -> buildlib
running install_lib
copying buildlibpl.py -> C:UsershuangchAppDataLocalProgramsPythonPython35Libsite-packages
byte-compiling C:UsershuangchAppDataLocalProgramsPythonPython35Libsite-packagespl.py to pl.cpython-35.pyc running install_egg_info Writing C:UsershuangchAppDataLocalProgramsPythonPython35Libsite-packagespl-1.0.0-py3.5.egg-info

5 测试

重新打开一个IDLE

>>> import pl
>>> pl.printTest()
this is a test  //验证成功
>>> 

6 以上内容完成后，就可以在任意的py文件中，来引用pl。同时还可以将pl上传到PypI社区，来分享代码。
