Python安装第三方包报错（InsecurePlatformWarning: A true SSLContext object is not available.） python

# 执行pip install dataset报错如下 InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. You can upgrade to a newer version of Python to solve this. For more information,see https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings InsecurePlatformWarning

解决方法
因为SSL的问题，urllib3需要pyopenssl。
