Install multiple versions of Rails on OSX

Rails
1

Hi,

I am currently running Rails 2.0.2 on my machine, but for the purposes
of a AWDR 2nd Edition, I also need to run Rails 1.8.6.

I looked around for a bit to find articles on how to do this, but I’m
coming up short.

Is there anyone out there that knows how to pull this off?

Thanks,

Justin

You mean 1.2.6?

1.8.6 is the version of Ruby, right?

The 3rd edition of the book is now beta and the source code is
compatible with Rails 2.0.2 already.

The second edition is based on Rails 1.2.3.

You can specify the version when you install Rails.

sudo gem install rails -v 1.2.3 –include-dependencies

If you are new to Rails and don’t wanna be confused with multiple
installations, I would suggest you uninstall Rails 2.0.2 first.

sudo gem uninstall -v 2.0.2 rails

If it’s just for learning, go get Locomotive. It’s a self-contained
pre-2.0 rails installation. When you’re done with it, just drop the
folder in the trash.
If you also get MAMP you’ll have a self-contained Mysql installation
too.

Justin,

Alternatively, you can keep your 2.02 and install 1.2.3 on the same
machine.

To specify which rails version to use, enter this when creating the
app:

rails 1.2.3 appname

instead of

rails appname

*keep the underscores around the version number.

./L

Awesome! I was trying to figure out how to create rails projects using a
specific version number, thanks!

I have 2.0.2 and 1.2.3 installed on the same machine and it seems to be
working fine so far.
