ruby - copy-history 实际上是复制 'copy-history'

Question

使用 pry 插件:pry-clipboard

当我输入“copy-history”来复制我历史的最后一行时，它实际上是在复制“copy-history”并粘贴“copy-history”。

我是不是漏掉了什么？即使我给它一个范围选项，它也会复制我的历史记录中没有的东西......

[19] pry(RSpec::ExampleGroups::MyHelperModuleWorks)> copy-history
-*-*- Copy history to clipboard -*-*-
copy-history
[20] pry(RSpec::ExampleGroups::MyHelperModuleWorks)>

~~~~

[5] pry(RSpec::ExampleGroups::MyHelperModuleWorks)> history
1: puts "this is what I want to copy"
2: puts "this also should get copied"
3: puts "and this..."
4: puts "but we don't want this"
[6] pry(RSpec::ExampleGroups::MyHelperModuleWorks)> copy-history --range 1..3

我遇到了同样的问题

[19] pry(RSpec::ExampleGroups::MyHelperModuleWorks)> copy-history
-*-*- Copy history to clipboard -*-*-
copy-history
[20] pry(RSpec::ExampleGroups::MyHelperModuleWorks)>

改变一行对我有用。
