我正在尝试使用Ansible 1.4.1在Ubuntu 12.04上使用nginx运行乘客Web服务器的安装.似乎gem安装正在搞乱或者其他什么,因为ansible找不到命令,当我重新安装时宝石手工制作.我究竟做错了什么？

# ruby.yml

- name: "install ruby"
  script: scripts/install_ruby.sh

- name: "Install bundler"
  gem: name=bundler state=latest

- name: "Install passenger"
  gem: name=passenger state=latest

- name: "Copy nginx upstart"
  copy: src=nginx.conf dest=/etc/init/nginx.conf mode=0644 owner=root group=root

- name: Install passenger-nginx
  command: passenger-install-nginx-module --auto-download --auto --prefix=/opt/nginx --extra-configure-flags='--with-http_gzip_static_module --with-http_secure_link_module --with-http_realip_module --with-http_ssl_module' creates=/opt/nginx

- name: "Enable Nginx"
  service: name=nginx state=started enabled=yes

当我进去时,我看到宝石存在：

root @staging-2：?#gem list

*** LOCAL GEMS ***

bigdecimal (1.2.3)
bundler (1.5.2)
daemon_controller (1.1.8)
io-console (0.4.2)
json (1.8.1)
minitest (4.7.5)
passenger (4.0.36)
psych (2.0.2)
rack (1.5.2)
rake (10.1.0)
rdoc (4.1.0)
test-unit (2.1.0.0)

但是,当我尝试运行install命令时,它仍然无法正常工作：

root@staging-2:~# passenger-install-nginx-module
passenger-install-nginx-module: command not found

它只有在重新运行时才有效：

gem install passenger

Ruby是从源代码安装的,这是我的gem env

root@staging-2:~# gem env

我看到GEM PATH目录中的可执行文件：

- /root/.gem/ruby/2.1.0

但显然这不会被添加到主要路径？

Ansible的gem模块可以在幕后使用–user-install option吗？

好吧,显然它是：http://docs.ansible.com/gem_module.html#gem-manage-ruby-gems

留下问题供其他人参考

解决方法:

因为你在Ubuntu上,只需使用Ansible通过apt-get安装the Phusion Passenger Debian packages(点击“Ubuntu”).它与apt-getting其他任何东西完全相同,比使用RubyGems安装要容易得多,甚至为你安装所有必需的依赖项(包括Ruby本身！)
