5 个解决方案
#1
As you have found, the -r option is your friend. It also works with IRB:
如您所见,-r选项是您的朋友。它也适用于IRB:
irb -ropen-uri
Will do the same as require 'open-uri'
会像'open-uri'那样做
FWIW, the most common thing I need to include via the command line is rubygems. And since newer versions of ruby come with gems built in I don't want to edit the file, but include it for testing. Luckily the folks who created gems added a little alias sugar.
FWIW,我需要通过命令行包含的最常见的东西是rubygems。而且由于新版本的ruby内置了宝石,我不想编辑文件,而是将其包含在测试中。幸运的是,创造宝石的人们添加了一点别名的糖。
You can do the following:
您可以执行以下操作:
ruby -rubygems myscript.rb
Instead of the ugly:
而不是丑陋的:
ruby -rrubygems myscript.rb
OK, so it is one character, but thought it was extra polish to make me happier.
好的,所以这是一个角色,但认为让我更快乐是额外的润色。

Actually, I found it. It's the -r command line entry.
实际上,我发现了它。这是-r命令行条目。
#3
You can use:
您可以使用:
require 'some_ruby_file'
in some-script.rb. It will load some_ruby_file.rb.
在some-script.rb中。它将加载some_ruby_file.rb。
#4
Before you call require "somefile.rb" you must navigate to the folder that the file is located or you must provide the full path. In example: require "~/Documents/Somefolder/somefile.rb"
在调用require“somefile.rb”之前,必须导航到文件所在的文件夹,或者必须提供完整路径。例如:require“〜/ Documents / Somefolder / somefile.rb”
#5
-r <library_name>
This causes Ruby to load the library using require.
这导致Ruby使用require加载库。
It is useful when used in conjunction with -n or -p.
与-n或-p一起使用时非常有用。
