崇高的文字无法理解gets.chomp [英] Sublime text can't understand gets.chomp

问题描述

我使用Sublime Text用ruby编写了这个简单的程序，由于某种原因，如果我使用Sublime text内置系统来构建它，则会收到以下错误消息

I wrote this simple program in ruby using Sublime Text and for some reason if I build it using Sublime text inbuilt system then I get the following error

`deposit': undefined method `chomp' for nil:NilClass (NoMethodError)

如果我使用cmd运行它，它将运行完美.

Its running perfectly if I run it using cmd.

class BankAccount
    def initialize(name)
        @transactions = []
        @balance = 0
    end
    def deposit
        print "How much do you want to deposit?"
        amount = gets.chomp
        @balance += amount.to_f
        puts "$#{amount} is deposited"
    end
    def show_balance
        puts "Your balance is #{@balance}"
    end
end
bank_account = BankAccount.new("Rohit Begani")
bank_account.class # => BankAccount
bank_account.deposit
bank_account.show_balance

推荐答案

Sublime无法自行处理交互式输入.您可以通过 SublimeREPL 运行脚本，也可以创建自定义的

Sublime can't handle interactive input on its own. You can either run your script through SublimeREPL or create a customized build system to open a command prompt and then run the code. Fortunately, this isn't too difficult. Create a new file in Sublime with the following contents:

{
    "cmd": ["start", "cmd", "/k", "c:/ruby193/bin/ruby.exe", "$file"],
    "selector": "source.ruby",
    "shell": true,
    "working_dir": "$file_dir"
}

将其另存为Packages/User/Ruby_cmd.sublime-build，其中Packages是选择Preferences -> Browse Packages...时打开的目录.选择Tools -> Build System -> Ruby_cmd，然后使用 Ctrl B 运行文件.

Save it as Packages/User/Ruby_cmd.sublime-build, where Packages is the directory opened when selecting Preferences -> Browse Packages.... Select Tools -> Build System -> Ruby_cmd, and run your file with CtrlB.

这应该适用于XP以上版本的所有Windows版本.但是，它不适用于OSX或Linux，因为它们没有start和cmd程序...

This should work on all versions of Windows from XP on up. It is not intended for OSX or Linux, though, as they don't have the start and cmd programs...
