Invalid excape character syntax

[adamp-2]

I'm brand new to RoR and Netbeans.  I've successfully gone through the demos and sample code.  When I try to create a project from scratch I and try to do Run/Debug Rake Task -> db:create, I get the following error.





Invalid escape character syntax: /C:\HelloWorld\Rakefile/

I have changed the NetBeans IDE to use the latest ruby 1.8.6_26 release, but that didn't help.



This has to be a

I am in the same boat as you, Adam. New in NetBeans and RoR. I am trying to create a new RoR and trying to connect to a MS SQL Server database. I tried to use my existing database connection (which uses JTDS driver). I don't know this will work or if that is the cause of the error

I've tried several things including using the RoR distribution and am still stuck.

Can you try whether you can successfully run Rake tasks from the command
line? Assuming you're using the bundled JRuby, open a command prompt for
the project directory and run some Rake task there, e.g.:

C:\YourRailsProjectDir><netbeans install
dir>\ruby2\jruby-1.1.4\bin\jruby -S rake db:create

(Obviously you need to replace <netbeans install dir> with the actual
path to your NB installation).

I tried that and it failed.  The error was:




Code:


C:\Documents and Settings\adamp\My Documents\NetBeansProjects\HelloWorld>"C:\Pro

gram Files\NetBeans 6.5.1\ruby2\jruby-1.1.4\bin\jruby" -S rake db:create

(in C:/Documents and Settings/adamp/My Documents/NetBeansProjects/HelloWorld)

Rails requires RubyGems >= 1.3.1 (you have 1.2.0). Please `gem update --system`

and try again.







I ran the update as suggested and got the following error:




Code:


C:\Documents and Settings\adamp\My Documents\NetBeansProjects\HelloWorld>"C:\Pro

gram Files\NetBeans 6.5.1\ruby2\jruby-1.1.4\bin\gem" update --system

operable program or batch file.

So I guess you're using some other Ruby platform than the bundled JRuby
for the app? Could you try running some rake task using the same
interpreter that you have set for the app (you can check the path to the
interpreter from Tools -> Ruby Platforms)?

You are correct that I have two ruby installs on my box they are:




Code:


Ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]

installed at: C:\ruby\bin







and:




Code:


JRuby 1.8.6 (2008-08-28 patchlevel 114) [java]

C:\Program Files\NetBeans 6.5.1\ruby2\jruby-1.1.4\bin\jruby.bat







Both my project specific Ruby envirnment and the overall Netbean env, as specified in Tools -> Ruby Platforms, point to the "JRuby 1.8.6 (2008-08-28 patchlevel 114) [java]"

OK; I see. I was asking since the original stack trace you posted
indicated that you use MRI Ruby, not JRuby. Is the error exactly the
same now that you're using JRuby, or is the error now the "Rails
requires  RubyGems  1.3.1" one? If the latter, probably the easiest is
to download and install JRuby 1.2.0 (jruby.codehaus.org) which bundles
RubyGems 1.3.1. Please see
http://blogs.sun.com/divas/entry/fixing_the_rails_requires_rubygems for
detailed instructions. Let us know if that helps,

Thanks,
Erno

OK, I got over the first issue.  It was quite painful, but sort of glad I had the process.  First I went through various update paths to get jruby up to date.  These are posted here http://blogs.sun.com/divas/entry/fixing_the_rails_requires_rubygems.  I also had to update the rails system with:




Code:
>jruby -S gem install -v=2.3.2 rails





Not sure how rails itself is out of date after a fresh install but whatever.  I then found out how to debug the entire Rake process:



1) Right Click <project name> -> Run/Debug Rake Task -> db:create

2) and check "Debug"



Debugging through I found that the system could not find the "mysql" gem at all.  Not only could I see it in the debugger, but in debug mode the actual error printed out so I did:



 
Code:
gem install mysql





To get the mysql gem installed.  I then reran rake db:create and that worked.



Finally I did:



1) Right Click <project name> -> Migrate Database -> To Current Version



And it worked.



I'm now on to routes problems, but I believe those errors being generated between the keyboard and the chair in my development environment.



So in a nut shell, you need to update your jruby install and install the mysql gem.



Thanks for help/pointers.

Adam

Hi Adam,

Great to hear it's working for you now. And thanks for posting your
notes, they will help others running into the same problem.

Cheers,
Erno
