我是 Ruby 新手，我发现了这个https://github.com/drodriguez/reversegeocoding，我觉得这听起来很酷。所以我尝试了示例应用程序，安装了所有东西，但是当我打电话时
thor geocoder:database
我收到此错误：
/Users/xyz/.thor/f892c2a1d732c61bbf4ebff2abb70df6:194:in `initialize': wrong number of arguments(2 for 0) (ArgumentError)
第 194 行显示
csv = FasterCSV.new(io, CSV_OPTIONS.merge(COUNTRIES_CSV_OPTIONS))
和整个方法
def insert_countries(db, countries)
ids = Hash.new
country_insert = db.prepare("INSERT INTO countries (name) VALUES (:name)")
open(countries, 'rb') do |io|
io.rewind unless io.read(3) == "\xef\xbb\xbf" # Skip UTF-8 marker
io.readline while io.read(1) == '#' # Skip comments at the start of the file
io.seek(-1, IO::SEEK_CUR) # Unread the last character that wasn't '#'
csv = FasterCSV.new(io, CSV_OPTIONS.merge(COUNTRIES_CSV_OPTIONS))
csv.each do |row|
country_insert.execute :name => row['country']
ids[row['ISO']] = db.last_insert_row_id
end
end
country_insert.close
ids
end
我不知道如何解决这个问题，我希望有人可以帮助我。
谢谢。
