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\test\pl>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 'dist\pl-1.0.0.zip' and adding 'pl-1.0.0' to it
 adding 'pl-1.0.0\PKG-INFO'
 adding 'pl-1.0.0\pl.py'
 adding 'pl-1.0.0\setup.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\test\pl>python setup.py install
 running install
 running build
 running build_py
 creating build
 creating build\lib
 copying pl.py -> build\lib
 running install_lib
 copying build\lib\pl.py -> C:\Users\huangch\AppData\Local\Programs\Python\Python35\Lib\site-packages
 byte-compiling C:\Users\huangch\AppData\Local\Programs\Python\Python35\Libsite-packages\pl.py to pl.cpython-35.pyc running install_egg_info Writing C:\Users\huangch\AppData\Local\Programs\Python\Python35\Lib\site-packages\pl-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。
