我正在尝试在 Windows 10 Enterprise 上开始使用 Python 3.6，但每当我尝试使用 pip 安装必要的软件包时，我总是会遇到类似的 SSL 错误。

pip install requests 给出以下错误：

Collecting requests
  Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:833)'),)': /simple/requests/

  Could not find a version that satisfies the requirement requests (from versions: )
No matching distribution found for requests

对于我尝试安装的所有 pip 包，我得到了类似的“重试”模式和失败错误。我尝试做“easy_install bioservices”，我得到了：

...

Installed c:\users\...\python\python36-32\lib\site-packages\requests_cache-0.4.13-py3.6.egg
error: The 'requests' distribution was not found and is required by bioservices

然后尝试做 pip install bioservices 给了我：

已满足要求：c:\users...\python\python36-32\lib\site-packages\bioservices-1.5.2-py3.6.egg 中的 bioservices 收集 grequests（来自 bioservices）重试（重试（总计 = 4 , connect=None, read=None, redirect=None, status=None)) 在连接被 'SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] 证书验证失败 (_ssl.c:833)'),)' 中断后：/简单/grequests/

我不知道如何解决这个问题。我正在使用 python 3.6.5 和 pip 9.0.3。我试过浏览许多不同的堆栈溢出问题和其他论坛，但都没有运气
