感觉还是Python用的人比较多，至少入门简单，使用也方便。
现在，我要发布一个Python应用，包名you-live，console命令you-live。
记录一下整个过程。

关于相对引用

因为某些问题，我把顶层的文件夹改了个名，于是引发了一些列的import错误。
此处应有相对引用，方便改动。具体就不说了，知道有这回事就行。

from ..src.folder1 import file1
from .folder1 import file2

另外，想引用同目录所在的包，应该注意以下要素：

import .folder1 	×
from . import folder1	 √

setup.py

要素过多，但一次填写后续项目基本大同小异。
对我而言，主要关心packages、requires、entry_points

import setuptools
import os
from live_recorder import version

with open("README.md", "r", encoding = 'utf-8') as fh:
    long_description  =  fh.read()

def find_packages(*tops):
    packages = []
    for d in tops:
        for root, dirs, files in os.walk(d, followlinks=True):
            if '__init__.py' in files:
                packages.append(root)
    return packages

REQ  =  ['PyExecJS', 'requests']

setuptools.setup(
    name = "you-live",
    version = version.__version__,
    description = version.__descriptrion__,
    author = "NiceLee",
    author_email = "lijia0732@sina.com",
    license = "MIT",
    long_description = long_description,
    long_description_content_type = "text/markdown",
    url = "https://github.com/nICEnnnnnnnLee/LiveRecorder",
    requires = REQ,
    install_requires = REQ,
    zip_safe = True,
    packages = find_packages('live_recorder'),
    classifiers = [

        "Intended Audience :: End Users/Desktop",

文件生成

确保前置环境OK

python3 -m pip install --user --upgrade setuptools wheel

生成分发文件
```
python3 setup.py sdist bdist_wheel
```

测试分发

正式发布前的可选操作，确保拥有Test PyPI账号

确保前置环境OK

python3 -m pip install --user --upgrade twine

将dist文件夹下的文件发布到TestPy

python3 -m twine upload --repository-url https://test.pypi.org/legacy/ dist/*

从TestPy安装包you-live

python3 -m pip install --upgrade --index-url https://test.pypi.org/simple/ you-live

(可选)卸载you-live
```
python3 -m pip uninstall you-live
```

正式分发

确保拥有PyPI账号

(可选)将账号写入配置

编辑~/.pypirc

  [distutils]
  index-servers = pypi

  [pypi]
  username:{username}
  password:{password}

确保前置环境OK

python3 -m pip install --user --upgrade twine

将dist文件夹下的文件发布到pypi
```
python3 -m twine upload dist/*
```

从pypi安装包you-live

python3 -m pip install --upgrade you-live
