只是玩Ruby并拥有这个非常基本的例子
runner.rb
:
require "bundler/setup"
include Mongo
mongo_client = MongoClient.new("localhost", 27017)
#mongo_client.database_names # lists all database names
#mongo_client.database_info.each { |info| puts info.inspect }
db = mongo_client.db("james_safety")
coll = db.collection("safety")
puts "above"
10.times { |i| coll.insert("i" => i) }
puts "Hello World"
Gemfile
:
source :rubygems
gem 'mongo'
bundle
输出:
Using bson (1.8.2)
Using mongo (1.8.2)
Using bundler (1.2.2)
Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
当我尝试运行ruby runner.rb
时,我收到此错误:
/Users/Tyler/Development/Ruby/JamesSaftey/runner.rb:2:in `<top (required)>': uninitialized constant Mongo (NameError)
from -e:1:in `load'
from -e:1:in `<main>'
如果require 'mongo'
中的runner.rb
,它可以正常工作(我在Gemfile之外安装了gem)。
我也试过require 'rubygems'
。没有不同。
我只是错误配置我的ruby文件以使用Gemfile吗?
Ruby 1.9.3
