忽略ssl证书以方便安装python

我的lib设置为

setup.py 

from setuptools import setup

setup(
    setup_requires=['pbr>=0.11.0'],
    pbr=True
)

setup.cfg 

[metadata]
name = MyLib

[options]
zip_safe = False
include_package_data = True
install_requires =
    cython
    pyrex
    pymssql
    elementtree
    bleach
    BeautifulSoup4
    pytz
    MySQL_python
    retry
    elementtree
    Pyrex
dependency_links =
    https://pypi.mydomain.com/packages/

[files]
packages =
    MyLib
    MyLib.package1
    MyLib.package1.new1

[tool:wheel]
universal = 1

[flake8]
exclude =
    venv,
    .tox,
    .git,
    __pycache__,
    *.pyc,
    *.egg-info,
    .cache,
    .eggs,
max-line-length = 80

[tool:pytest]

ignore=
    .tox
    .cache
    docs
    config.py
    venv

[coverage:run]
omit=
    MyLib/config.py

我正在应用程序MyLib中使用此requirements.txt

myapp / requirements.txt ... ... MyLib == 1.2.3 ... ...

我在安装/usr/local/pyenv/versions/myapp/bin/pip install -i https://pypi.mydomain.com --trusted-host pypi.mydomain.com -r /opt/school/apps/myapp/requirements.txt时将其重定向到pypi.python.org。然后我得到easy_install使用另一个配置作为~/.pydistutils.cfg。我添加为

〜/ .pydistutils.cfg 

[easy_install]
index_url=https://pypi.mydomain.com/
find_links = https://pypi.mydomain.com/simple/
allow_hosts = pypi.mydomain.com

现在，它没有重定向到pypi.python.org，但它为SSL提供了错误。

  1. 是否有任何方法可以强制dependency_links不使用~/.pydistutils.cfg？

如果1的回答为“否”，那么如何为我的pypi服务器忽略SSL？

尝试了下面给出的解决方案。

1 个答案:

答案 0 :(得分：3)

here中提到的问题是

  

setuptools正在尝试与PyPI进行对话，而不是与pip进行对话，   并且macOS上的3.6.0默认情况下无权访问CA Bundle   setuptools不会像pip那样捆绑一个。你需要   安装诸如certifi之类的东西或引起setuptools问题。

您可以强制安装新版本的pip，

curl 'https://bootstrap.pypa.io/get-pip.py' > get-pip.py
sudo python get-pip.py

您还可以尝试安装上述问题中提到的certifi，

pip install certifi
  

Certifi是精心策划的根证书的集合，用于   验证SSL证书的可信度，同时验证   TLS主机的身份。它已从请求中提取   项目。

可以使用--trusted-host禁用TLS，但这是危险的，根本不推荐。

pip install --trusted-host pypi.python.org pip --upgrade
