Python-安装时间表模块时出错

如何解决Python-安装时间表模块时出错

我正在尝试在我的环境中安装时间表模块，但出现此错误：

C:\Users\fernando.fidalgo\PycharmProjects\prospec_estudos\venv\Scripts>pip install schedule
Collecting schedule
  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:749)'),)': /simple/schedule/
  retrying (Retry(total=3,)': /simple/schedule/

那是我的python版本：

Python 3.6.0 | Anaconda 4.3.1（32位）| （默认值为2016年12月23日， 12:06:52）在Win32上使用[MSC v.1900 32位（Intel）]

我已经将其安装在这台机器上，但是在其他环境中。
