With help from this excellent group, I was able to install Rails. The next step was to upgrade Rails. I tried both ways as suggested by the documentation and got errors from each...
C:\Sites>
gem update --system
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError) SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://api.rubygems.org/specs.4.8.gz)C:\Sites>
gem install rails
ERROR: Could not find a valid gem 'rails' (>= 0), here is why: Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://api.rubygems.org/specs.4.8.gz)
I reviewed the links given in the comments, but I really did not understand them...sorry. I hope there is a straightforward solution. Thanks
I looked at the Go Rails site and that requires a Linux subsystem which seems like more than I need and was not mentioned by the instructor for the online course. I already have everything installed for running Rails, but the final step is to upgrade Rails from 4.2 to 5.0 and that is where the error occurs.
I also looked at the website that was said to be a possible duplicate and did what it said and no change. Why is this so difficult?
The answer was above. First execute gem sources -a http://rubygems.org and agree to the less secure http, then gem install rails works and upgrades to 5.0.0.1
