Ruby Gem install fails on Windows because of SSL

Tags: , ,

When installing the Openshift rhc client I need to install a Ruby gem on Windows. This resulted in an error message:

C:\Users\user>gem install rhc
ERROR:  Could not find a valid gem 'rhc' (>= 0), here is why:
          Unable to download data from https://rubygems.org/ - SSL_connect retur
          ned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (
    https://api.rubygems.org/latest_specs.4.8.gz)

This is because the Ruby network client is unable to verify the SSL Certificate Authority. Via Google a found a Gist
which explains how this can be fixed. I found the manual way the fastest way, since I
will not be using gem for other projects.

In short I did this:

Download http://curl.haxx.se/ca/cacert.pem to c:\temp

Executed in command prompt:
set SSL_CERT_FILE=c:\temp\cacert.pem

After this executing the command to install the client tools worked:

C:\temp>gem install rhc

After fixing the SSL issue I encountered a second problem during the setup command, after the SSH key step
the client would attempt to write a file to the H:\ drive. It assumed that that was my homedrive, while it does not exist.

It turns out that there are two environment variables that define the HOME folder on Windows: HOMEPATH and HOMEDRIVE. Set
the combination of these two to a writable folder. For example to your user dir on Windows. These environment variables can be
set in two ways: via the commandline (where they will be forgotten after closing the shell windows), or via the Advanced Properties
of the About dialog of My Computer.

The simplest way via the commandline is:

    SET HOMEPATH=\users\user
    SET HOMEDRIVE=C:
