ruby - 如何将 `--with-ruby-include` 之类的构建标志传递给 gem 安装？

Question

(我知道我的 Ruby 安装有点乱，但是:)我正在尝试安装 native gem，但出现错误

ytg@yui:~> sudo /usr/bin/ruby.ruby2.3 /usr/bin/gem install ruby-debug-ide
Building native extensions.  This could take a while...
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
    --without-make-prog
    --srcdir=.
    --curdir
    --ruby=/usr/bin/$(RUBY_BASE_NAME).ruby2.3
    --with-ruby-dir
    --without-ruby-dir
    ---with-ruby-include
    --without-ruby-include=${ruby-dir}/include
    --with-ruby-lib
    --without-ruby-lib=${ruby-dir}/lib64

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

  /usr/lib64/ruby/gems/2.3.0/extensions/x86_64-linux/2.3.0/debase-0.2.2.beta9/mkmf.log

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/lib64/ruby/2.3.0/rubygems/gem_runner.rb:55:in `run'
    /usr/bin/gem:21:in `<main>'

有没有办法让 gem install 识别那些头文件？

Answer 1

您必须使用 -- 将构建标志与选项分开。

来自help page : (gem install --help)

Usage

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

Extension Install Failures

If an extension fails to compile during gem installation the gem specification is not written out, but the gem remains unpacked in the repository. You may need to specify the path to the library’s headers and libraries to continue. You can do this by adding a -- between RubyGems' options and the extension's build options:

$ 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]
