Python:无法连接到HTTPS URL,因为SSL模块不可用

我正在尝试连接到Stripe来设置付款。我在我的开发机器上运行它,但是当我推到生产时,我得到以下SSL错误:

    • 无法连接到HTTPS URL,因为SSL模块不可用。**

以下是我的设置的详细信息:

  • Ubuntu 16.04
  • Apache2
  • mod_wsgi
  • Python 3.6语言
  • Django 1.11
  • Python/Django进程都安装并运行在一个名为"ProtectYourReviews"的Anaconda(Miniconda)虚拟环境中

我读过很多其他的SO回答,他们建议重新安装python,但是要确保先安装依赖项。当安装inside和anaconda环境时,这应该不是一个问题吧?anaconda不应该为我处理所有的依赖项吗?
我已经启用了HTTPS,并且可以在整个域运行(所有请求都被路由到https)。当我检查安装时,我确实有openssl,当我在django环境中打开shell时,我可以导入和使用模块,没有问题...所以我不知道如何继续解决这个问题。
任何帮助都是非常感谢!

  • 此外,这里有一个堆栈跟踪:*

在一个新的python virtualenv中重新安装mod_wsgi后,它仍然试图打开旧的anaconda路径。我已经在WSGIDaemonProcess中更改了python-home和python-path指令,但无论我如何尝试,它仍然试图从miniconda3目录(我已经删除了该目录)打开python。
以下是Apache错误日志中的跟踪:

是的,我确实从一个干净的源目录开始。我把mod_wsgi tar文件复制到新目录,并在新目录中运行configure/make/make install。我相信我在新安装之前也删除了apache模块文件,以防万一。
我尝试了多次迭代下面的指令(both/only python-home/only python-path),但是无论我怎么尝试,我都弄不明白为什么mod_wsgi一直在查找已删除的miniconda3文件夹。
下面是我的wsgi.load:

LoadModule wsgi_module /usr/lib/apache2/modules/mod_wsgi.so

下面是我的Apache2指令(其中pyr_env是我的新Python virtualenv文件夹):

WSGIDaemonProcess protectyourreviews python-home=/home/user/pyr_env/ python-path=/home/user/protectyourreviews
WSGIProcessGroup protectyourreviews

WSGIScriptAlias / /home/user/protectyourreviews/zz_test/test.wsgi

问题是Anaconda Python自带SSL库,编译Python ssl模块时不使用系统SSL库,Apache中的mod_ssl模块使用系统库。
因此,如果你在Apache中启用mod_ssl,它会拉入系统SSL库。当Python ssl模块被你的应用程序导入时,它会继承已经加载的系统SSL库,这与ssl模块被编译的目的和预期不同,因此它会失败。
所以这个问题是由Anaconda Python忽略系统SSL库而使用自己的库引起的。
唯一的解决方案是使用系统Python版本而不是Anaconda Python,或者在主Apache安装后使用mod_wsgi-express运行WSGI应用程序,主Apache安装只充当SSL的终止点,然后代理mod_wsgi-express示例。
除非您有特定的要求,否则最好使用系统Python版本,而不是Anaconda Python。
