在运行时会提出SNIMissingWarning和InsecurePlatformWarning警告
详细警告内容如下:
SNIMissingWarning
D:\Python2.7.6\lib\site-packages\requests\packages\urllib3\util\ssl_.py:120: 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
终端更新pip出错 sudo pip install --upgrade pip :
1.ReadTimeoutError: HTTPSConnectionPool(host=’pypi.python.org’, port=443): Read
解决办法: 加大超时时间,如 pip --default-timeout=100 install -U pip
2.如果依上处理还没解决问题,或者报错 ProtocolError: ("Connection broken: error(54, 'Connection reset by peer')", error(54, 'Connection reset by peer'))
解决办法:
1. 到https://pypi.python.org/simple/pip/下载最新的.whl文件(如pip-8.1.2-py2.py3-none-any.whl,注意:列表并非按发布时间排序,自己按文件名找到最新.whl文件)
2. 下载完之后,在终端下用pip安装: pip install (path)/pip-8.1.2-py2.py3-none-any.whl
其实在使用pip安装一些包文件的时候如果遇到这样的问题,也是可以通过加大超时时间或者直接下载要安装文件的整个安装包来安装。
