使用ruby​​-2.0.0-p0：

string = "{:name=>\"2012 Honda Civic EX-L\", :price=>\"23100\", :dealer_name=>\"T AND T HOND\", :dealer_website=>\"http://autocatch.com/dealer/t-and-t-honda/index.htm\", :phone=>\"(888) 364-1858\", :ad=>\"1167269\", :stock=>\" 2120054N\", :year=>\"2012\", :make=>\"Honda\", :model=>\"Model Civic\", :trim=>\"EXL\", :mileage=>\"4629\", :body_style=>\"Coupe\", :transmission=>\"Automatic\", :ext_colour=>\"White\", :int_colour=>\"Grey\", :doors=>\"2Door\", :passengers=>\"Passengers \", :drive_train=>\"Front Wheel Drive\", :engine=>\"1.80\", :cylinders=>\"4Cylinder\", :fuel_type=>\"Type Gas\", :certified=>\"\", :e_tested=>\"\"}\n"
hash = eval(string)
hash[:name] # => "2012 Honda Civic EX-L"

你到底得到了什么错误？

反斜杠只是转义引号；它们实际上不在字符串中。至于eval解析它，如果它来自受信任的来源，请使用并让 Ruby 解析它。
