Question

我正在尝试为Rails项目执行'bundle install'。但是我被击中了

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.

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.

然后我试了

$ gem install debugger -v '1.5.0'

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.

所有宝石都已正确安装，但宝石安装因宝石调试器（1.5.0）而停止

我的宝石环境是：

$ gem env

提前致谢。

Answer 1

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，看看是否有效！

Answer 2

您使用的是JRuby还是IronRuby？ debugger不适用于JRuby（请参阅here），但我从未尝试使用IronRuby。

Answer 3

调试器gem仅适用于CRuby（MRI）。如果您使用的是不同的Ruby实现，则需要使用该平台本机的调试器。

This blog post解释了如何基于Ruby平台有条件地包含不同的调试宝石。

Answer 4

如果您使用的是RVM并且没有正确采购，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

Rails安装调试器（1.5.0）会引发错误
