ruby.exe: No such file or directory — /cygdrive/c/ruby/bin/gem (LoadError)

When attempting to install a gem using cygwin on a Windows XP machine I received the below error. I was hoping I wasn’t going to have to reinstall RubyGems underneath cygwin because it would have just been a pain. I had Ruby installed and operational underneath cygwin but for some reason rubygems was not working. I decided to instead make an alias to point to the gem command that I had installed straight to Windows. Use the below command to add an alias to cygwin to make gem an available command.

Error: ruby.exe: No such file or directory — /cygdrive/c/ruby/bin/gem (LoadError)

To resolve use the below command from your cygwin bash prompt to create an alias for gem. On my laptop Ruby is installed in C:\ruby so the commands are located in C:\ruby\bin.

I was recently working on a Perl script that would SSH to another server and run a sudo command on the remote server that was failing. The error that was received is below.

Error: sudo: sorry, you must have a tty to run sudo

The reason for this is an update along the way with sudo locked it down further by adding the below line to /etc/sudoers configuration file.

Zen Cart Error Debug: Checkout Process Showing a Blank Page

Recently I had a Zen Cart store showing a completely blank page during the checkout process. With the default settings we were unable to find out what the issue was so we needed to figure out a way for more debugging. To easily accomplish a verbose debug log of each action on the site you can download a Zen Cart add-on called “Debug Error Logging Utility”. This add-on will provide details of each page processed on the site or for the administration section. Follow the directions below to enable more logging.
