Installing ruby gems on Windows

Posted by jpluimers on 2017/11/06

Steps:

  1. Install the Ruby Installer from rubyinstaller.org/downloads
  2. Add the directory where Ruby got installed to the user PATH (using "%windir%\System32\rundll32.exe" sysdm.cpl,EditEnvironmentVariables) in my case C:\Ruby23\bin as I installed Ruby 2.3.1
  3. Install the CA certificates:
    1. Download https://curl.haxx.se/ca/cacert.pem to the Ruby directory (C:\Ruby32)
      • Note this used to be at http://curl.haxx.se/ca/cacert.pem but serving that over http instead of https does not much sense when you want to secure your connections.
    2. Add the environment variable SSL_CERT_FILE with value C:\Ruby23\cacert.pem (again using "%windir%\System32\rundll32.exe" sysdm.cpl,EditEnvironmentVariables).

If you forget step 3, then you get errors like this:

C:\Users\jeroenp>gem install gist
ERROR:  Could not find a valid gem 'gist' (>= 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)

C:\Users\jeroenp>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)
