ruby-debug 不会安装/构建 native 扩展

Question

我一直在寻找解决方案。我有两个 linecache19和 ruby_core_source安装。

这些命令都不起作用:

gem install ruby-debug19
gem install ruby-debug19 -- --with-ruby-include=/Users/benjohnson/.rvm/src/ruby-1.9.1-p378

这是我不断收到的错误:

Building native extensions.  This could take a while...
ERROR:  Error installing ruby-debug19:

Answer 1

我遇到了同样的问题(在 1.9.1 和 1.9.2 上)。即使尝试安装 0.11.23 也会触发错误。我发现有必要:

卸载 gem(我的所有版本):
gem uninstall ruby-debug-base19

删除 0.11.24 目录(在我的例子中:~/.rvm/gems/ruby-1.9.2-p0/gems/ruby-debug-base19-0.11.24/)

明确安装 0.11.23:
gem install ruby-debug-base19 --version=0.11.23

这是我得到大部分解决方案的地方: http://rails.brentsowers.com/2010_08_01_archive.html

此外，如果您使用 Bundler:

在升级到最新的 Bundler(1.0.2 => 1.0.7)之前我遇到了问题，因为它坚持安装 ruby​​-debug-base19 v 0.11.24)。

在你的 Gemfile 中，确保你已经固定了 ruby​​-debug-base19 的版本:
gem "ruby-debug-base19", "0.11.23", :require => nil
