最近业务需要抽离，抽离出来的应用需要做成 Django 第三方包的形式，可以在任何 DjanGo（也没那么神奇，例如有些版本就没测试）版本项目中，直接安装使用，所以这里还是需要发包到 pypi。
第一次发包
我是先发到 test 环境 https://testpypi.python.org/，看下发包还是不是符合我的预期，毕竟很长时间没发过包。
twine upload -r pypitest dist/django-xxxxx-0.0.1.tar.gz
Uploading distributions to Https://test.pypi.org/legacy/
Uploading django-xxxxx-0.0.1.tar.gz
0%| | 0.00/18.5k [00:00<?, ?B/s]
SSLError: HTTPSConnectionPool(host='test.pypi.org', port=443): Max retries exceeded with url: /legacy/ (Caused by SSLError(SSLError(1, u'[SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:661)'),))
结果打脸，查了下资料，http://pyfound.blogspot.hk/20...，摘出来一部分
There are two deadlines to upgrade your Python to a version with the latest TLS. The first comes soon, on April 30, 2017, when python.org sites without Extended Validation Certificates will stop supporting TLS 1.0 and 1.1. These sites include:testpypi.python.org
test.pypi.org
files.pythonhosted.org
大意是什么呢，意思就是提醒赶紧升级 python，那个后面只会只支持使用 TLS 1.2 版本的协议，低版本的不再支持了，很不幸，testpypi.python.org 这个测试站点停止支持 TLS 1.0 和 1.1
接着按照给出的例子，自己测了下
python -m pip install --upgrade requests
python -c "import requests; print(requests.get('https://www.howsmyssl.com/a/check', verify=False).JSON()['tls_version'])"
TLS 1.0If you see "TLS 1.2", your interpreter's TLS is up to date. If you see "TLS 1.0" or an error like "tlsv1 alert protocol version", then you must upgrade. ↩
第二次发包
按照文档上讲的，我的 python 过时了，那就直接升到 2.7.14；升完再跑一遍
python -c "import requests; print(requests.get('https://www.howsmyssl.com/a/check', verify=False).json()['tls_version'])"
/Users/allen/Develop/py3env/lib/python3.6/site-packages/urllib3/connectionpool.py:858: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings
InsecureRequestWarning)
TLS 1.2
这下是否可以省心了，继续我的发包
twine upload -r pypitest dist/django-xxxxx-0.0.1.tar.gz
Uploading distributions to https://test.pypi.org/legacy/
Uploading django-xxxxx-0.0.1.tar.gz
0%| | 0.00/18.5k [00:00<?, ?B/s]

第三次发包
twine upload -r pypitest dist/django-xxxxx-0.0.1.tar.gz
Uploading distributions to https://test.pypi.org/legacy/
Uploading django-xxxxx-0.0.1.tar.gz
100%|███████████████████████████████████████████████████████████████████████████████████████████████████| 18.5k/18.5k [00:08<00:00, 2.13kB/s]终于跑起来了，小结下
- 如果 Python 版本低，升级
- 如果 pyOpenSSL 版本低，升级
- 如果 requests 版本低，升级
