使用Ansible安装RBENV

Question

我正在尝试使用Ansible在服务器上安装RBENV，但要获得此错误：

任务：[rbenv |创建临时目录] * ** * ** ** ** ** ** * ** * **** 致命：[localhost] =>条件表达式必须评估为true或false：is_failed（$ rbuild_present）

致命：所有主机都已经失败 - 流产

我的剧本是：

---
- name: rbenv | update rbenv repo
  git: repo=git://github.com/sstephenson/rbenv.git
       dest=$rbenv_root
       version=v0.4.0
- name: rbenv | add rbenv to path
  file: path=/usr/local/bin/rbenv
        src=${rbenv_root}/bin/rbenv
        state=link
- name: rbenv | add rbenv initialization to profile
  template: src=templates/rbenv.sh.j2
            dest=/etc/profile.d/rbenv.sh
            owner=root
            group=root
            mode=0755
- name: rbenv | check ruby-build installed
  command: test -x /usr/local/bin/ruby-build
  register: rbuild_present
  ignore_errors: yes
- name: rbenv | create temporary directory
  shell: mktemp -d
  register: tempdir
  when_failed: $rbuild_present
- name: rbenv | clone ruby-build repo
  git: repo=git://github.com/sstephenson/ruby-build.git
       dest=${tempdir.stdout}/ruby-build
  when_failed: $rbuild_present
- name: rbenv | install ruby-build
  command: ./install.sh
           chdir=${tempdir.stdout}/ruby-build
  when_failed: $rbuild_present
- name: rbenv | remove temporary directory
  file: path=${tempdir.stdout} state=absent
  when_failed: $rbuild_present
- name: rbenv | check ruby $ruby_version installed
  shell: RBENV_ROOT=${rbenv_root} rbenv versions | grep $ruby_version
  register: ruby_installed
  ignore_errors: yes
- name: rbenv | install ruby $ruby_version
  shell: RBENV_ROOT=${rbenv_root} rbenv install $ruby_version
  when_failed: $ruby_installed
- name: rbenv | set global ruby $ruby_version
  shell: RBENV_ROOT=${rbenv_root} rbenv global $ruby_version
  when_failed: $ruby_installed
- name: rbenv | rehash
  shell: RBENV_ROOT=${rbenv_root} rbenv rehash
  when_failed: $ruby_installed
- name: rbenv | set gemrc
  copy: src=files/gemrc
        dest=/root/.gemrc
        owner=root
        group=root
        mode=0644

有什么想法？

我怀疑您正在使用最新的Ansible或> 1.3.x。when_语法已被弃用，当您运行剧本时，它应该给您警告。而是使用以下内容：

when: ruby_installed|failed

或类似的东西：

when: 'not ($ruby_installed)'
