color-theme-install undefined

I updated to GNU emacs 23.3.1, and my configuration file, which worked under GNU emacs 23.1.1, gives m开发者_Go百科e an error that says color-theme-install is void. Is there any way that I can fix it?

It sounds like you don't have color-theme.el installed. Try the installation instructions.

There was a problem with require in the file. It is solved now.
