我是Python的新手，正在尝试在Windows7上使用> pip install linkchecker。
无论软件包是什么，
- pip安装都会失败。例如，
> pip install scrapy也会导致SSL错误。Python3.4.1的 - Vanilla install包含pip 1.5.6。我尝试做的第一件事就是安装链接检查器。Python2.7已经安装好了，它附带了ArcGIS。在我安装3.4.1.
> pip search linkcheckerworks之前，无法从命令行使用python和pip。也许这是因为pip搜索不会在公司网络中验证站点的SSL am，但我们不会通过代理来访问Internet.- Each公司的计算机(包括我的计算机)具有受信任的根证书颁发机构，该机构用于各种原因，包括启用对https://google.com流量的监控。我不确定这是否与此有关。
以下是运行pip install linkchecker后我的pip.log的内容
