我正在尝试为 Rails 项目执行“捆绑安装”。但我被打动了

Installing debugger (1.5.0)
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension
.

        c:/jruby-1.7.4/bin/jruby.exe extconf.rb
NotImplementedError: C extension support is not enabled. Pass -Xcext.enabled=tru
e to JRuby or set JRUBY_OPTS or modify .jrubyrc to enable.

Gem files will remain installed in c:/jruby-1.7.4/lib/ruby/gems/shared/gems/debu
gger-1.5.0 for inspection.

by_debug/gem_make.out
An error occurred while installing debugger (1.5.0), and Bundler cannot
continue.
Make sure that `gem install debugger -v '1.5.0'` succeeds before bundling.

然后我尝试了

$ gem install debugger -v '1.5.0'

complete
ERROR:  While executing gem ... (Errno::EACCES)
    Access to the path 'c:\Program Files\IronRuby 1.1\Lib\ruby\gems\1.9.1\source
_cache' is denied.

所有 gem 均已正确安装，但 gem 调试器 (1.5.0) 的 gem 安装停止

我的宝石环境是：

$ gem env

提前致谢。

NotImplementedError: C extension support is not enabled. Pass -Xcext.enabled=true to JRuby or set JRUBY_OPTS or modify .jrubyrc to enable.

这似乎是你的问题，所以只需启用 JRuby 的 C 扩展支持，看看它是否有效！

你是用JRuby还是IronRuby？debugger不适用于JRuby（请参阅此处），但我从未尝试过使用IronRuby.

调试器 gem 仅用于 CRuby (MRI)。如果您使用不同的 Ruby 实现，则需要使用该平台的原生调试器。

Chris Gaffney 的这篇博客文章解释了如何有条件地包含基于 Ruby 平台的不同调试 gem。

如果您使用的是 RVM 并且来源不正确，则可能会发生这种情况。

user$ source ~/.rvm/scripts/rvm

并确保以下命令返回“rvm is a function”

user$ type rvm | head -n 1
rvm is a function
