忽略 ssl 证书以便于安装 python

Question

我的库设置为

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]
testpaths=MyLib/tests
ignore=
    .tox
    .cache
    docs
    config.py
    venv

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

我在我的应用程序requirements.txt 中使用这个MyLib

myapp/requirements.txt ... ... 我的库==1.2.3 ... ...

当我使用/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 安装时，它正在重定向到pypi.python.org。然后我知道easy_install 正在使用另一个配置为~/.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，但它给出了 SSL 错误。

1. 有什么办法可以强制dependency_links 不使用~/.pydistutils.cfg 吗？

如果1 的答案是否定的，那么如何忽略我的pypi 服务器的SSL？

尝试了下面给出的解决方案。

Answer 1

here 提到的问题是，

setuptools 正在尝试与 PyPI 对话，而不是 pip， 并且 macOS 上的 3.6.0 默认情况下无法访问 CA Bundle 并且 setuptools 不像 pip 那样捆绑一个。你需要 安装 certifi 之类的东西或使用 setuptools 提出问题。

你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

您也可以尝试安装certifi，如上一期所述，

pip install certifi

Certifi 是一个精心策划的根证书集合，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，但它危险，根本不推荐。

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