Starting rails server on 3.0.5 gives Psych::SyntaxError - Parsing YAML

Hello,

I just updated to using Rails 3.0.5 and was on Ruby 1.9.2p0 but
replaced that with 1.9.2p180 to try and get the over problem below but
am unable to. After creating a new project and adding a few gems to
Gemfile and bundle install (and update to make sure) when I try to
start the server with "rails s" command I get the error below - no
other controllers/models/views added.

I have Googled around and I find two things

1. Suggestion to add the two lines below to the top of boot.rb file

require ''yaml''
YAML::ENGINE.yamler= ''syck''

.... but it doesn''t work ... gives another YAML parsing error

2. I see in some posts/places that the issue has been identified and
fixed and someone (Aaron?) is in the process of updating the releases
- so I did a bundle update to make sure I have the latest stuff and
got the latest Ruby version. Still get the error below.

It would seem like I am missing something simple and obvious here
otherwise I would expect lot more posts on this topic in this forum
but I don''t see any here. Thanks for your help and pointers to get
over this - I am in a Windows 7 box. If I need to revert back to some
older version of Ruby/Rails to get past this error I am happy to do
that - just starting out migrating from 2.3.8 to 3.0.

Thanks,
-S

Sounds to me like there is a syntax error in your database.yml file
(possibly at line 36)

Re: Starting rails server on 3.0.5 gives Psych::SyntaxError - Parsing YAML

Hi,

I have the same problem; I re-installed ruby & rails

ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-linux]
Rails 3.0.5

I got this parsing error, when psyche.rb tried to parse my de.yml locale
file which contains a German umlaut:

de:
    previous: zurück
    next: weiter

When I change this file to

de:
    previous: zurueck
    next: weiter

the problem does not appear anymore. What in the hell is a locale file
worth when it cannot contain local characters? Did anyone test this code
with a different file than en.yml?

Hi Fred,

no - quoting doesn''t help :-( would be quite a task to quote everything
in a large de.yml file...

I suppose that the parser does not like UTF-8.

We had this happen to a custom YML file... culprit ended up being two dashes
instead of the required three dashes to start off the yaml file...  only came up
for a colleague using ruby 1.9.x...

I notice none of my locale files have any dashes at all though, but for what
it''s worth...

my de.yml consists of three lines:

de:
    previous: zurück
    next: weiter

This one fails. When I change ''zurück'' to
''zurueck'', it works. It seems
apparent that the umlaut ''ü'' causes the problem. Or any other
idea?
