Dep not found a valid gem in any repository

[edgarjaviertec]

I work with ruby on windows.

I have the exact same problem in Debian Wheezy. The gem command is created with the wrong syntax. dep is running:

gem install gem_name:0.1.2

instead of:

gem install gem_name -v 0.1.2

If I manually run the second command it works as expected.

Update:

In the latest version of rubygems you can indicate the version of the package with the syntax of the first command. I'm currently using rubygems version 1.8.23 and with this version the new syntax isn't supported.
