Versuche, von Ruby 1.8.7 auf 1.9.2 zu aktualisieren, während du immer noch Rails 2.3.8 verwendest

Question

Wenn ich bundle exec script/server -p3001 mache, bekomme ich folgenden Fehler / Stacktrace =(

Wie kann ich das beheben? Also, die Syntax, auf die es verweist, ist wirklich merkwürdig... aber das hat in 1.8.7 funktioniert =\

Answer 1

Überprüfen Sie die Syntax, ich hatte ein ähnliches Problem:

Syntaxfehler, unerwartet '{', erwartet ';' oder '\n' (SyntaxError)
              def hash_for_{:create=>:post, :delete=>:pos...

wo ich ein Array für den :collection-Schlüssel anstelle einer Hash in der routes.rb-Datei gesendet habe. Also hatte ich dies:

:collection => [ :next => :get, :prev => :get, :sort => :post ]

und geändert zu:

:collection => { :next => :get, :prev => :get, :sort => :post }

Hoffe das hilft...
