Python HTTPS下载失败，原因是“<urlopen error unknown url type:HTTPS>”

Question

我正在尝试在一个非常小的系统（Ubuntu 16.04 docker image）上从源代码构建一个python2.7，它不会因为<urlopen error unknown url type: https>而导致HTTPS下载失败。我不想使用包管理器，但我知道这可以很容易地解决问题。在

我浏览了Unknown url type error in urllib2，并将不同的引用补丁应用到setup.py，将Modules/Setup和{}中的SSL变量设置为我传递给OpenSSL 1.1.1的./config --prefix的安装前缀，并将{}设置为OpenSSL安装前缀。在

我怀疑这样一个最小的系统比另一个答案中建议的要多。为什么configure没有--with-ssl开关？在

            # need to install into explicit prefix different from `/usr/local` in order to make OpenSSL get picked up by Python's patched `configure` (specifying `OPENSSL_ROOT=/usr/local` doesn't work)

git clone git://git.gnome.org/jhbuild && cd jhbuild && ./autogen.sh --prefix=/usr/local && make && make install && cd ..

我选择jhbuild bootstrap作为测试命令，因为这是所需的结果，请随意建议一个更好的结果。在

我在https://gitlab.com/krichter/jhbuild-docker-build创建了一个SSCCE，它允许在GitLab CI中运行构建脚本，并且可以在https://gitlab.com/krichter/jhbuild-docker-build/-/jobs/53948513上研究包含完整构建日志的运行示例。在

我可以让它在<urlopen error [SSL: NO_CIPHERS_AVAILABLE] no ciphers available (_ssl.c:661)>（我在FIXME中处理）之后失败

• 将 prefix=/usr/local/ openssldir=/usr/local添加到OpenSSL的config中
• 应用https://gist.githubusercontent.com/rkitover/2d9e5baff1f1cc4f2618dee53083bd35/raw/7f33fcf5470a9f1013ac6ae7bb168368a98fe5a0/python-2.7.14-custom-static-openssl.patch，如上述参考问题所述，以及

• 修补Modules/Setup.dist和{}
