尝试使用 pip 时出现运行时错误

Question

我做了一些看似无害的事情，成功地把自己搞砸了。

我从我的 python 脚本（品牌 ['feed'] = 我正在向其发出请求的 URL）收到以下错误：

**C:\Python27\lib\site-packages\requests\packages\urllib3\util\ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.

  InsecurePlatformWarning

Traceback (most recent call last):

    r = adapter.send(request, **kwargs)

    raise SSLError(e, request=request)

requests.exceptions.SSLError: [Errno 1] _ssl.c:507: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed**

所以我问了互联网，互联网说这样做：

pip install --upgrade ndg-httpsclient

所以我做到了，现在当我运行相同的脚本时我不断收到 RuntimeError，疯狂的是即使我只是尝试运行 pip 在 shell，我得到同样的错误！！

我搜索了这个错误，但似乎找不到任何有用的信息。我在 Windows Server 2008 R2 Standard 64 位

上使用 python 2.7.6
