我需要一个debugger-linecache版本1.0.1 ,并且在尝试安装时遇到以下错误。

trunk ☺  gem install debugger-linecache -v '1.0.1'
Building native extensions.  This could take a while...
ERROR:  Error installing debugger-linecache:

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
    --with-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib

Gem files will remain installed in /Users/jordanscales/.rvm/gems/ruby-1.9.3-p194/gems/debugger-linecache-1.0.1 for inspection.

此错误表示所选版本debugger不支持当前的Ruby版本。有两种解决方案:

  1. debugger通过更新gembundle update debugger。新版本debugger与旧的Ruby版本向后兼容,所以这是修复它的最好方法。
  2. 降级你的Ruby版本。

这可能会帮助你

gem install debugger-linecache -v '1.1.2' -- --with-ruby-include=$rvm_path/src/ruby-1.9.3-p286/
