Question

我正在制作一个宝石，我想在irb上测试它。

我成功运行gem build gemname.gemspec，然后gem install ./gemname-0.0.0.gem。宝石名称出现在gem list本地宝石下。

当我在irb并且需要'gemname'时，它会显示

LoadError: cannot load such file -- gemname
    from /Users/iggy/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require'
    from /Users/iggy/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require'
    from (irb):1
    from /Users/iggy/.rvm/rubies/ruby-2.2.1/bin/irb:11:in `<main>'

我已经按this post，this one，this one和其他一些方式查看了答案。仍然得到LoadError。

我的宝石环境：

Igors-MacBook-Air:gemname iggy$ which ruby

确保只有一个ruby在运行（有两个版本，但我将其更改为如下所示）

Igors-MacBook-Air:gemname iggy$ which -a ruby
/Users/iggy/.rvm/rubies/ruby-2.2.1/bin/ruby

当前红宝石版

Igors-MacBook-gemname iggy$ ruby -v
ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-darwin14]

不确定这个命令是做什么的，但我之前看到的其中一个帖子建议运行它：

Igors-MacBook-Air:gemname iggy$ gem env | grep 'RUBY EXECUTABLE'
  - RUBY EXECUTABLE: /Users/iggy/.rvm/rubies/ruby-2.2.1/bin/ruby

任何有助于摆脱require 'gemname'的{{1}}的帮助都将受到高度赞赏。

Answer 1

问题解决了。

首先，我在gemname文件夹中创建Gemfile。内部看起来像：

# A sample Gemfile
source "https://rubygems.org"
gemspec
# gem "rails"

重新安装了gem，Gemfile.lock已创建。

然后我通过bundle exec irb运行irb，而不是输入irb。

require 'gemname'有效。

运行时的Ruby loadError需要irb上的'gemname'
