spawn: can't convert nil into string

[tukinu]

hello, I just installed dandelion but I get an error everytime I try to connect: ....Ruby193/lib/ruby/gems/1.9.1/gems/posix-spawn-0.3.6/lib/posix/spawn.rb:162:in `spawn': can't convert nil into string

I'm on a windows 7 machine with a fresh version of ruby and dandelion 0.3.8. I guess is not really a dandelion problem but maybe someone can help me.

Thanks a lot for any support.

Do you have a stack trace? My guess is that the error is coming from the "Grit" library that Dandelion uses to interact with the Git repo.

I have the same issue too

[scttnlsn]

Yeah, sorry- not sure what to tell you guys. This is definitely out of the scope of Dandelion. You might consider opening an issue with Grit (if there's another way to execute commands that is more cross platform) or try running this in cygwin.

[sukihub]

Grit incorrectly parses PATH on Windows (splits it using : and tries to find git instead of git.exe). Workaround is to manually set path to Git executable like this: Grit::Git.git_binary = 'C:\wherever_you_have_git\bin\git.exe'

[laurencedorman]

sukihub, would you be so kind as to tell me where I need to add this line to set the path to the Git executable?
