Question

（我知道我的Ruby安装有点乱，但是:) 我正在尝试安装本机gem，它给了我一个错误

ytg@yui:~> sudo /usr/bin/ruby.ruby2.3 /usr/bin/gem install ruby-debug-ide

ERROR:  Error installing ruby-debug-ide:

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
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib64
    --with-make-prog

    ---with-ruby-include
    --without-ruby-include=${ruby-dir}/include
    --with-ruby-lib

To see why this extension failed to compile, please check the mkmf.log which can be found here:

但是当我尝试添加建议的参数时，我得到：

ytg@yui:~> sudo /usr/bin/ruby.ruby2.3 /usr/bin/gem install ruby-debug-ide --with-ruby-include="/usr/include/ruby-2.3.0/"

    /usr/bin/gem:21:in `<main>'

有没有办法让gem install识别这些头文件？

Answer 1

您必须使用--将选项标记与选项分开。

来自help page :( gem install --help）

用法

gem install GEMNAME [GEMNAME ...] [options] -- --build-flags [options]

后来：

扩展安装失败

如果在gem安装期间扩展无法编译，则不会写出gem规范，但gem仍会在存储库中解压缩。您可能需要指定库的标头和库的路径才能继续。您可以通过在RubyGems的选项和扩展的构建选项之间添加--来实现此目的：
$ gem install some_extension_gem
[build fails]
Gem files will remain installed in /path/to/gems/some_extension_gem-1.0 for inspection.
Results logged to /path/to/gems/some_extension_gem-1.0/gem_make.out

$ gem install some_extension_gem -- --with-extension-lib=/path/to/lib
[build succeeds]

如何将像`--with-ruby-include`这样的构建标志传递给gem install？
