无法安装红宝石红宝石计价器

Question

用厨师来安装千分表。它在尝试安装gem ruby-j量表时失败。

试图手动安装宝石。

(1:91)# ./gem install ruby-jmeter
Building native extensions.  This could take a while...
ERROR:  Error installing ruby-jmeter:
    ERROR: Failed to build gem native extension.

进一步观察，似乎它依赖于另一个创业板nokogiri。

Building nokogiri using packaged libraries.
Using mini_portile version 2.0.0.rc2
checking for gzdopen() in -lz... yes
checking for iconv using --with-opt-* flags... yes

所以试着安装nokogiri，看看它为什么会失败。所以它抱怨没有正确的libxml2版本

(1:105)# ./bin/gem install nokogiri -- --use-system-libraries
Building native extensions.  This could take a while...
ERROR:  Error installing nokogiri:
    ERROR: Failed to build gem native extension.

        /opt/chef/embedded/bin/ruby extconf.rb --use-system-libraries
checking if the C compiler accepts ... yes
Building nokogiri using system libraries.
libxml2 version 2.6.21 or later is required!
*** extconf.rb failed ***

我尝试使用yum安装libxml2库，发现它已经安装好了。

(1:111)# yum install libxml2
Loaded plugins: versionlock
Setting up Install Process
Package libxml2-2.7.6-20.el6_7.1.x86_64 already installed and latest version
Nothing to do

那么，真正的问题是什么，以及如何解决它。enter code here

所以我做了一些更多的研究，发现开发包丢失了，这是构建nokogiri宝石所必需的。

因此，安装了libxml2 & libxslt的开发包。

(1:113)# yum install libxml2-devel

一旦安装了这两个yum pakage，就成功地安装了红宝石。
