Error starting config app: `join': can't convert nil into String (TypeError)

[Julio Napurí Carlos]

Hi

Download and install the new version RailsInstaller 2 uploaded by
Wayne, after a report that Rails was outdated. (3.1.0 rc6)

I finish installation and I check option:
Configure git and ssh when installation has completed.

But when the script started I get the following:

c:/RailsInstaller/scripts/config_check.rb:12:in `join': can't convert
nil into String (TypeError)
from c:/RailsInstaller/scripts/config_check.rb:12:in `<main>'
c:\Sites>_

NOTE:
I removed previous install version (RailsInstaller 2)

This means you were one of the first downloading the installer.

This error happens because your system/configuration lacks either
HOMEDRIVE or HOMEPATH environment variables.

You can check that opening a new command prompt (not the
RailsInstaller one) and do:

SET HOMEDRIVE
SET HOMEPATH

If one of those is undefined, that is the reason of the error.

Now, Since Windows 2000 these variables are present, and if they
aren't something is corrupt on your system.

Can you tell us what is the output of the following command?

SET USER

You should see something like this:

USERDOMAIN=KEORE
USERNAME=Luis
USERPROFILE=C:\Users\Luis
