pip安装失败，提示“连接错误:[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:598)”;
我对Python很陌生，正在尝试在Windows 7上使用> pip install linkchecker。一些注意事项:
- 无论软件包是什么，PIP安装都失败。例如，
> pip install scrapy也会导致SSL错误。 - Python 3.4.1的香草安装包含pip 1.5.6。我尝试做的第一件事是安装链接检查器。Python 2.7已经安装，它是随ArcGIS一起安装的。
python和pip在我安装3.4.1之前从命令行是不可用的。 - # EYZ0作品。也许这是因为pip搜索不验证站点的SSL证书。
- 我在一个公司的网络，但我们不通过代理到达互联网。
- 公司的每台计算机(包括我的)都有一个受信任的根证书颁发机构，用于各种原因，包括启用对https://google.com的TLS流量监控。不知道这和这事有什么关系。
下面是运行pip install linkchecker后我的pip.log的内容:
