I also used `remove-pkg', but it also seemed to recompile more than needed (although a lot less than install-pkg). This time I did not stop it. It removed the package, but then when I tried to re-execute the file where which holds my call to remove-pkg, I get the following error: procedure get-compiled-file-sha1: expects 1 argument, given 2: #<path:reader_rkt.zo> #<path:compiled\drracket\errortrace> It did the same thing with install-pkg, but I thought that this was because I killed the compilation process. It can't be that now, because I didn't kill it this time. So I quit DrRacket, delete the compiled directory of my file, run DrRacket, execute the file, but I still get the error. Now I need to remove and reinstall Racket entirely again to have it work. Maybe this is my fault, but I don't know where.
