git-rails init can''t find HOME environment
I''m trying to teach myself version control using GIT on a Windows
machine for my ROR development. I downloaded and ran the cygwin and it
created the following files:
''./.bashrc'' -> ''/home/Wayne//.bashrc''
''./.bach_profile'' ->
''/home/Wayne//.bash_profile''
''./.inputrc'' -> ''/home/Wayne//.inputrc''
Wayne@Gateway ~
$
I also installed the gem git-rails
I''ve created a project and did a cd to that project.
Now when I run get-rails init I receive what looks like an error
finding my HOME path as follows:
C:/ruby/lib/ruby/gems/1.8/gems/git-rails-0.2.1/bin/git-
rails:12:in `expand_path'': couldn''t find HOME
environment --
expanding `~'' (ArgumentError)
from C:/ruby/lib/ruby/gems/1.8/gems/git-rails-0.2.1/bin/git-rails:12
from C:/ruby/bin/git-rails:19:in `load''
from C:/ruby/bin/git-rails:19
Any ideas?

That fact alone would have persuaded me to go a different route. Why not actually download and install git? I am in the same position as you: I am learing git(as of 3 days ago) but on a mac. But you installed cygwin, so that means you should have a unix like environment to work with, and we should be in the same boat. I downloaded git itself and installed it. I used this tutorial to start: Starting with git using just 10 commands (I''m only using 5 so far) http://blog.xkoder.com/2008/08/13/git-tutorial-starting-with-git-using-just-10-commands/ But it was hard to find a tutorial that actually tells you how to rollback to a previous version of your code. This one does: http://www-cs-students.stanford.edu/~blynn/gitmagic/ch02.html#_saving_state (see section Advanced Undo/Redo--I''m not sure why it''s titled "Advanced" since it''s so basic.) -- Posted via http://www.ruby-forum.com/.

In unix, the ''~'' is shorthand for your the directory your account has been assigned to, e.g. /Users/joe blow So whenever you want to use that path, you can use ''~'' instead of typing that out by hand. That path is also the value of the $HOME environment variable on my computer. Maybe when you write "~", unix substitutes in the value of $HOME. The error message indicates that the gem is using "~" in its code somewhere, and that it couldn''t find $HOME to substitute in a path for ''~''. To check if an environment variable is set in cygwin, do this: <some prompt here> $HOME ...that is type $HOME after your prompt in cygwin. I get this result: ~/2testing/dir1$ $HOME -bash: /Users/myname: is a directory To see all the environment variables that are set, do this: <some prompt here> set -- Posted via http://www.ruby-forum.com/.

And another thing... To permanently set an environment variable for bash, set the environment variable in the .bash_profile file: HOME="/home/Wayne" You might also want to add a comment to any change you make to .bash_profile, so that in the future you will know why you made the change that you did. Comments are preceded by: # Spaces are not superfluous, so write the assignment exactly as written above. -- Posted via http://www.ruby-forum.com/.
