cannot load such file -- ffi_c

[simonharrer]

When using vagrant 0.9 on win 7 64bit with ruby 1.9.3 p0 MRI, the command vagrant init works as expected. However, invoking vagrant up next results in this error:

Ah 64-bit. Yay. I'll investigate and see if I can get to the bottom of this.

[mitchellh]

Can you give this a shot? http://stackoverflow.com/questions/7964778/no-such-file-to-load-ffi-c-loaderror

FFI is a dependency of a dependency on Vagrant, so I'll let that gem author know as well.

[mitchellh]

Also, what version of FFI is installed now?

[jarib]

Looks like this issue.

[simonharrer]

I uninstalled all ffi gems except ffi-1.0.9-x86-mingw32. Then, vagrant worked. Thus, it is the issue @jarib mentioned with the follow up of ffi/ffi#182 , which sadly have not been resolved.

Finally, I can use Ruby 1.9.3 MRI with Vagrant on Win7 :) Thanks!

[mitchellh]

Great! So dumb. Closing this issue because this is really an FFI issue and I don't think locking Vagrant to FFI 1.0.9 is a good choice.
