Amazon Linuxでserverspecのインストールはできるが、

serverspec-initができない。

Amazon LinuxのAMI IDはamzn-ami-hvm-2017.03.0.20170417-x86_64-gp2 (ami-923d12f5)、

Rubyのバージョンはruby 2.0.0p648 (2015-12-16) [x86_64-linux]、

rakeのバージョンはrake, version 12.0.0。

 
serverspec-initを実行すると、


[ec2-user@ip-192-168-11-11 serverspec]$ serverspec-init

となる。

ログを見て、ああ、io-consoleがないのね、と思い、gem install io-console するが、


[ec2-user@ip-192-168-11-11 serverspec]$ gem install io-console
Fetching: io-console-0.4.6.gem (100%)
Building native extensions. This could take a while...
ERROR: Error installing io-console:
ERROR: Failed to build gem native extension.

/usr/bin/ruby2.0 extconf.rb
mkmf.rb can't find header files for ruby at /usr/share/ruby/include/ruby.h

Gem files will remain installed in /home/ec2-user/.gem/ruby/2.0/gems/io-console-0.4.6 for inspection.

となる。

むむーーーーーー

ヘッダーファイルがみつからない的なエラーが出ているため、

sudo yum -y install ruby-devel

したが変わらず。

それではということで、

sudo yum install -y ruby20-devel gcc-c++

したらio-consoleインストールできた!!!!!!!!!

 
というわけで、無事serverspec-initもできた。

最近のAmazon LinuxのRubyだと起きる・・?
