Question

当我在新创建的rails应用程序中运行rails generate controller welcome index时，我得到以下答案

Ignoring nokogiri-1.6.6.2 because its extensions are not built.  Try: gem pristine nokogiri --version 1.6.6.2
Ignoring json-1.8.2 because its extensions are not built.  Try: gem pristine json --version 1.8.2
Ignoring binding_of_caller-0.7.2 because its extensions are not built.  Try: gem pristine binding_of_caller --version 0.7.2
Warning: Running `gem pristine --all` to regenerate your installed gemspecs (and deleting then reinstalling your bundle if you use bundle --path) will improve the startup performance of Spring.
Ignoring binding_of_caller-0.7.2 because its extensions are not built.  Try: gem pristine binding_of_caller --version 0.7.2

但是没有生成控制器文件。
运行gem pristine --all会得到以下结果：

Restoring gems to pristine condition...
Skipped bigdecimal-1.2.6, it is a default gem
Restored bundler-1.11.2
Restored bundler-1.10.6
Building native extensions.  This could take a while...
Restored curb-0.9.1
Skipped io-console-0.4.3, it is a default gem
Skipped json-1.8.1, it is a default gem
Restored minitest-5.4.3
Restored power_assert-0.2.2
Skipped psych-2.0.8, it is a default gem
Skipped rake-10.4.2, it is a default gem
Skipped rdoc-4.2.0, it is a default gem
Restored test-unit-3.0.8

在运行发生器之前，我完成了

$ rails new testapp
$ cd testapp

我的ruby版本是ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-darwin15]，我的rails版本是Rails 4.2.1，我正在使用rbenv。

我想这几乎不可复制......但我找不到任何帖子来帮助我。我不是Ruby on Rails的新手，但我暂时没有使用它。

感谢您的帮助。

不确定为什么它解决了我的问题，但是从rbenv切换到RVM就可以了。

在此之前，我在运行rails server：

让我进入了其他论坛，最终我决定尝试使用RVM。

rails generate controller失败，“忽略binding_of_caller-0.7.2，因为它的扩展没有构建。”
