ruby - Ocra 在打包脚本时抛出错误

Question

SCENARIO

我已经安装了 Ruby 2.1.5 (x64)包然后我安装了Ocra gem 成功:

gem install ocra
Fetching: ocra-1.3.3.gem (100%)
Successfully installed ocra-1.3.3
Parsing documentation for ocra-1.3.3
Installing ri documentation for ocra-1.3.3
Done installing documentation for ocra after 0 seconds
1 gem installed

PROBLEM

我正在尝试打包测试脚本:

# -*- coding: UTF-8 -*-

# require ''
exit if Object.const_defined?(:Ocra)

print "Hello World!"
sleep 3

__END__

但是当我尝试使用 Ocra 时，它会抛出错误:

ocra "TestScript.rb"

QUESTION

为什么会这样？如何解决？

Answer 1

问题源于安装irb1.8而不是 irb 依赖包。如果您已经安装了 irbl.8，只需执行“apt-get install irb”即可解决该问题。
