Python 2.7.11 [SSL : CERTIFICATE_VERIFY_FAILED]

Question

我想要做的是从网站打开一个 xml.zip 文件，以介绍 Python 项目。我很确定我的代码没有任何问题，但是当我运行程序时，我得到:

Traceback (most recent call last):
  File "/Users/Chris/Documents/clientDownloadFile-Handout.py", line 16, in <module>
    u = urllib2.urlopen("https://nvd.nist.gov/download/nvdcve-Recent.xml.zip")
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 154, in urlopen
    return opener.open(url, data, timeout)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 431, in open
    response = self._open(req, data)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 449, in _open
    '_open', req)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 409, in _call_chain
    result = func(*args)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 1240, in https_open
    context=self._context)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 1197, in do_open
    raise URLError(err)
URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)>

这是我的代码:

import urllib2

u=urllib2.urlopen("https://nvd.nist.gov/download/nvdcveRecent.xml.zip")

localFile = open('nvd.xml.zip', 'wb')
localFile.write(u.read())
localFile.close()

我做了一些研究，包括在这个网站上。我尝试了一些修改，如“导入 ssl”和其他“不安全”的解决方法来解决这个问题，但无济于事。我想知道是否有其他人(可能是 Mac OS X El Capitan 用户)遇到过这个问题，是否有更安全的方法解决这个问题？
