如何在Software Collections环境中控制ruby-devel的存在

Question

我目前正在尝试在Centos 6.6机器上构建一个Ruby应用程序.通过软件集合安装了不同的Ruby堆栈.请注意,我的机器上没有root,我的权限有限,特别是它们不包括软件包安装.

本机扩展不构建.它似乎ruby-devel缺失了,但管理员告诉我它已正确安装两个堆栈:

dnf install rh-ruby22-ruby-devel.x86_64 ruby193-ruby-devel.x86_64 -y

这是我的问题:

bob@server ~> scl enable rh-ruby22 bash
bash-4.1$ ruby -v
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-linux-gnu]

bash-4.1$ gem install json Building native extensions.  This could take a while... ERROR:  Error installing json:
        ERROR: Failed to build gem native extension.

    /opt/rh/rh-ruby22/root/usr/bin/ruby -r ./siteconf20150625-17536-saskmd.rb extconf.rb mkmf.rb can't find header files for ruby at /opt/rh/rh-ruby22/root/usr/share/include/ruby.h

extconf failed, exit code 1

Gem files will remain installed in ~/.gem/ruby/gems/json-1.8.3 for inspection. Results logged to ~/.gem/ruby/extensions/x86_64-linux/json-1.8.3/gem_make.out

如何ruby-devel(更准确地说rh-ruby22-ruby-devel.x86_64)是否正确安装？

如果它按预期工作,下一个搜索的地方是什么？

Answer 1

这很可能是因为您没有为SCLo ruby​​版本安装devel库.

sudo yum install rh-ruby22-ruby-devel
