无法安装 ruby​​ gem ruby​​-jmeter

Question

使用 chef 安装 jmeter。它在尝试安装 gem ruby-jmeter

时失败

尝试手动安装 gem

(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宝石 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

因此尝试安装 nokogiri 以了解其失败的原因。所以它抱怨没有正确版本的 libxml2

(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

Answer 1

所以我做了更多研究，发现缺少开发包，这是构建 nokogiri gem 所必需的。

所以安装了 libxml2 和 libxslt 的开发包

安装这两个 yum 包后，ruby-jmeter gem 安装成功
