通过命令行往python私仓传包
文章发布较早，内容可能过时，阅读注意甄别。
# 1，前言
提供了Python私仓之后，除了通过私仓拉包方便之外，小伙伴们难免会有往私仓传包的需求，因为稍微有点绕弯，因此这里记录一下。
其实用一句话来表述，就是通过私服拉包的时候，走group的代理，从本地上传包的时候，要走local的仓库。
接下来就记录一下配置方法并用测试包来验证下。
创建私服的过程这里不详述了，已知现有Python私仓，物料信息如下：
- group：http://nexus.test.com/repository/pyg/
- local：http://nexus.test.com/repository/pyg/
# 2，上传
# 1，先安装依赖包
$ pip3 install wheel --user
$ pip3 install twine --user

# 2，添加配置
有了如上物料之后，我们首先来验证下上传功能，在本地用户家目录添加如下配置：
$ cat ~/.pypirc
[distutils]
index-servers =
pypi
nexus
[pypi]
repository:https://pypi.python.org/pypi
username:eryajf
password:test
[nexus]
repository=http://nexus.test.com/repository/pyg/
username=dev
password=GVLaX-E|yq$vE[/k

# 3，编写代码
然后在本地打一个测试包
$ mkdir helloworld
$ touch helloworld/__init__.py
$ cat helloworld/demo.py
class Demo:
@staticmethod
def hello():
print('helloworld')

编写setup.py：
$ cat setup.py
from setuptools import setup
setup(
name='helloworld',
version='1.0',
author="techlog",
license="MIT",
packages=[
'helloworld'
],
install_requires=[
],
classifiers=[
"Topic :: Utilities",
"Topic :: Internet",
"Topic :: Software Development :: Libraries :: Python Modules"
],
)

打包之后，会生成一个build目录和dist目录：
$ tree

看到如上内容，就说明上传成功了。
可以浏览器上看下：
# 3，下载
拉包就比较简单了，首先配置如下信息：
mkdir ~/.pip
cat > ~/.pip/pip.conf << EOF
[global]
timeout = 60
trusted-host = nexus.test.com
index-url = http://nexus.test.com/repository/pypi/simple
EOF
