I have installed ruby 2.1.5 version and want to downgrade it to 1.9.3 to avoid "DL is deprecated, please use Fiddle in windows". I have tried rmv function, but it is not working and also tell me how to remove older versions.

1Simply uninstall 2.1.5 (like any other program or find the link in the start menu) and install 1.9.3 or better yet 2.2.2!? – cremno Aug 01 '15 at 12:50

That message is a totally ignorable warning by the way - it's not an error message and won't stop ruby working – Frederick Cheung Aug 01 '15 at 13:10

@rasevanth looks like there are more details, please edit the question and add more details (such as when that message occurs and what happens after that). – Tamer Shlash Aug 01 '15 at 13:40

So what's the issue ? Does migration complete ? If you mind just for the warning about DL being deprecated, downgrading to already unsupported Ruby version sounds ridiculous.
This may be just quite unharmful notice for developers to start using newer C-extension interface, while functionality is kept unaffected.

@rasevanth "Browser" ?? Please look into logs after migration task, to see what really happened. If it is a standard Rails project, they should reside in `
/log` subdirectory - `development.log`, `production.log` etc. based on environment being run in. – joanbm Aug 01 '15 at 17:37
