我可以将enthought python重新连接到Mac OS X上的新版openssl吗？

Question

今天早上,我在Mac OS X 10.6.8上使用EPD 7.3遇到了与SSL相关的问题.当我运行pip(版本1.3.1)时,我得到:

pip install requests
Downloading/unpacking requests
  Could not fetch URL https://pypi.python.org/simple/requests/: There was a problem confirming the ssl certificate: <urlopen error [Errno 1] _ssl.c:504: error:0D0890A1:asn1 encoding routines:ASN1_verify:unknown message digest algorithm>
  Will skip URL https://pypi.python.org/simple/requests/ when looking for download links for requests

我想我遇到了https://github.com/pypa/pip/issues/829和https://groups.google.com/d/msg/python-virtualenv/C_a_IX_8Ejc/83l8XfpUarQJ中详述的问题-也就是说,链接到python的openssl版本太旧了:

python -c"import ssl; print ssl.OPENSSL_VERSION"

回报

OpenSSL 0.9.7l 2006年9月28日

我的问题是,我是否可以将EPD Mac版本的Python链接到更新版本的openssl - 或者这是Enthought需要做的改变吗？

(我只是想在我的Mac上编译openssl(使用http://techscienceinterest.blogspot.com/2010/12/compiling-openssl-on-mac-os-x-snow.html上的说明)并使用homebrew来构建我自己的Python可执行文件使用较新版本的openssl(http://hackercodex.com/guide/python-virtualenv-on-mac-osx-mountain-lion-10.8/).

Answer 1

雷蒙德,感谢你的报道.EPD的继任者现在处于测试阶段,包含OpenSSL 0.9.8r 8 Feb 2011并且没有这个问题.(FWIW,它还包含requests您在遇到SSL问题时尝试安装的最新版本.)

它很快就会出现测试版,但与此同时,如果您想在那里试用,我会看到您已经有测试版邀请函.

我们还将研究EPD 7.3的可能修复或解决方法.
