Question

I was trying to push my local database to Heroku and received this error:

...Taps Server Error: PGError: ERROR: time zone displacement out of range:...

Some googling later I discovered that this error doesn’t occur with ruby 1.9.2 and that (because being on windows) I’d have to install pik to run 1.9.2 alongside 1.9.3. So I installed pik and ruby 1.9.2.

However, when I try to install rails on 1.9.2 I get this error:

...ERROR: Failed to build gem native extension...

After plenty of googling I’ve ran into the following:

• Don’t bother using windows for ruby/rails development 🙁
• Something to do with devkit?
• Or installing a binary kit version of rails?
• Compile it yourself

Any help is much appreciated!

EDIT:

The relevant part of the error message is gcc: Command not found; so the compiler is not available to compile the code locally.

If you already have gcc installed on your machine somewhere, make sure it is included in the PATH.
