我有ruby2.2，ubuntu 14.04.4 LTS，我想安装rsruby gem。一切都已设置好，所有其他宝石都已设置完成，并附带“sudo bundle install”。但当我尝试安装它时，rsruby不断崩溃。如何调试并使其工作？
我运行了一个运行此命令的脚本
sudo bundle config build.rsruby "--with-R-include=/usr/share/R/include --with_cflags=\"-fPIC -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wall -fno-strict-aliasing\""
然后我运行“sudo bundle install”并在RSRuby上崩溃：
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
/usr/bin/ruby2.2 -r ./siteconf20161028-31919-l2ks0n.rb extconf.rb

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.

An error occurred while installing rsruby (0.5.5), and Bundler cannot
continue.
但如果我跑
sudo gem install rsruby -- --with-R-dir=/usr/lib/R --with-R-include=/usr/share/R/include --with_cflags="-fPIC -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wall -fno-strict-aliasing"
然后成功安装

This could take a while...

所以，我的问题是，我该如何调试呢？如何使用捆绑安装？谢谢！
UPDATE，正如matt在评论中指出的那样，两个命令安装的rsruby gem的版本是不同的。如果我更改我的Gemfile以指定bundle来安装版本“0.5.1.1”，那么“sudo bundle install”安装成功。但是，我需要版本“0.5.5”。我的Gemfile目前设置如下，“gem'rsruby'，github：'custora / rsruby'”，必须得到版本0.5.5。那么为什么0.5.1.1会正确安装，而不是0.5.5？
更新，mkmf.log

答案 0 :(得分：0)
好的，所以这里发生了一些不同的事情。我将在这里记录所有内容以防其他需要使用rsruby的人遇到此问题。首先，正如Matt指出的那样，bundle install和gem install试图安装两个不同版本的rsruby。其次，我必须更改我运行的脚本以设置捆绑配置选项，此脚本不起作用。为此，我将\"替换为'
#!/bin/bash
# Does /usr/bin/gem link to /usr/bin/gem2.1 ?
# gem install bundler -v 1.6.0.rc2
sudo bundle config build.rsruby "--with-R-include=/usr/share/R/include --with-cflags=\"-g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -fPIC\""
以上两个步骤进行了rsruby安装。但在那之后我总是遇到段错误。问题似乎是ubuntu的旧版本，或者因为它是ubuntu的旧版本，我不得不使用brightbox repo来获得更新版本的ruby。在任何情况下，在更新到当前版本的ruby的当前版本的linux后，它都有效。
