I am very new to Python and trying to
> pip install linkchecker on Windows 7. Some notes:
- pip install is failing no matter the package. For example,
> pip install scrapyalso results in the SSL error.
- Vanilla install of Python 3.4.1 included pip 1.5.6. The first thing I tried to do was install linkchecker. Python 2.7 was already installed, it came with ArcGIS.
pipwere not available from the command line until I installed 3.4.1.
> pip search linkcheckerworks. Perhaps that is because pip search does not verify the site"s SSL certificate.
- I am in a company network but we do not go through a proxy to reach the Internet.
- Each company computer (including mine) has a Trusted Root Certificate Authority that is used for various reasons including enabling monitoring TLS traffic to https://google.com. Not sure if that has anything to do with it.
Here are the contents of my pip.log after running
pip install linkchecker:
