Question

代码@db = SQLite3::Database.new 'db.db'与ruby-1.9.3-p194完美配合，并使用ruby-2.0.0-p353（rvm 1.24.7）返回错误：

wrong argument type nil (expected Hash) (TypeError)

我无法使用Google搜索任何解决方案。

UPD ：irb没有错误。只有我自己的代码：

# encoding: utf-8
require 'sqlite3'

class Model
  attr_reader :files, :last

  def initialize(dbPath = 'photo.db', tags = '', lastID = 0)
    @tags = tags
    @lastID = lastID
    $log.debug() {"Loading database: #{dbPath}..."}
    @db = SQLite3::Database.new dbPath
  end
...

它在日志中生成此跟踪：

我修复了它，用#!/usr/bin/ruby替换了可执行脚本#!/usr/bin/env ruby。
