I tried building node.js on Cygwin and that caused errors, so someone in #node.js on freenode told me to run
rebaseall on Cygwin to clean it up. So I tried that and I got the following message:
rebaseall: only ash or dash processes are allowed during rebasing
Exit all Cygwin processes and stop all Cygwin services.
Execute ash (or dash) from Start/Run... or a cmd or command window.
Execute '/bin/rebaseall' from ash (or dash).
So I closed Cygwin, went to Start/Run and tried
dash but got the following alert:
Windows cannot find 'ash'. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.
So what am I supposed to do?
