“syntax error, unexpected tIDENTIFIER, expecting $end”

问题

I put together this script based on this tutorial.

require 'nokogiri'
require 'open-uri'

url = "http://sfbay.craigslist.org/sby/jjj/"

data = Nokogiri::HTML(open(url))

puts data.at_css('.itempn').text
puts data.at_css('.itemcg').text

I keep getting this error:

Macintosh:nokogiri rgrush$ ruby aaa.rb
aaa.rb:1: syntax error, unexpected tIDENTIFIER, expecting $end
url = "http://sf...
                      ^

Any ideas? Could it be that one of my dependencies is out of date?

回答1:

most likely you have a non ASCII char in URL.

try adding

# encoding: UTF-8

as first line of aaa.rb

so it will look like:

# encoding: UTF-8
require 'nokogiri'
require 'open-uri'
