Rails 奇怪的错误 =>索引错误:字符串不匹配 [英] Rails strange error => IndexError: string not matched

问题描述

我收到了一个非常奇怪的消息错误.我认为它不是来自 Ruby 而是来自 unix 系统.

I've got a very strange message error. I think it's not coming from Ruby but from the unix system.

所以，我有以下测试文件:

So, I have the following test file:

require File.dirname(__FILE__) + '/../test_helper' 

class CatTest < ActiveSupport::TestCase
    def test_truth
    assert true
   end
end

因此，Fixtures 目录中的 YAML 文件没有任何内容.

So, nothing coming from YAML files in the Fixtures directory.

当我使用以下命令运行上面的测试时:

When I run the test above with the command:

$ ruby ./test/unit/cat_test.rb

我得到了非常奇怪的结果:

I get the very strange result:

Loaded suite ./test/unit/cat_test
Started
E
Finished in 0.011252 seconds.

  1) Error:
test_truth(CatTest):
IndexError: string not matched


1 tests, 0 assertions, 0 failures, 1 errors

我找不到错误的含义

IndexError: string not matched

但最奇怪的是，昨天，它奏效了！

But the most strange is that yesterday, It worked!

非常感谢您的帮助.

推荐答案

例如，当您错误地尝试将字符串变量作为 Hash 访问时，就会发生这种情况.

This happens, for example, when you try to access a string variable as a Hash by mistake.

s = "a string"
s["position"] = "an other string"

IndexError: string not matched
    from (irb):5:in `[]='
    from (irb):5
