I get lot of bug reports related to this issue, and I’ll like to explain that is not a bug in the software, but a bug in your setup.
Why? you may ask? because you’re mixing a native interpreter version of Ruby (One-Click built for Windows) with a posix emulation layer which is Cygwin.
That basically will end in several problems.
- Cygwin relies on shebangs of the scripts, Windows doesn’t. Since One-Click installer ships with several gems bundled, all those need to be fixed prior shipment.
- Building extensions will segfault (since you’re mixing a native program with a emulated extension) (if you succeeded in the compilation process.
The first point will fail always. If the shebang got fixed by default to
/usr/bin/ruby it will not find it in
/cygdrive/c/ruby/bin/ruby.exe and thus failing.
So, please, take this as good advice. If you want to use Cygwin, use it fully, including the bundled ruby version.
If you want Windows-native applications and libraries, use One-Click Installer.
If you miss bash and similar tools to mimic Linux, use MSYS instead of Cygwin.
Again: do not mix the environments, bad things happens doing it.
