Ansible playbook 尝试使用复杂的开关运行 make 和 configure 时不起作用

这是这问题。我正在尝试使用 Ansible 来配置 Vagrant VM。该 VM 正在运行 CentOS 6.4。我正在使用以下（简化的）ansible playbook：

- hosts: default
  vars:
    home: '/home/vagrant'
    curl_version: '7_19_7'
    curl_url: 'https://github.com/bagder/curl/archive/curl-{{ curl_version }}.tar.gz'
    curl_dir: '{{ home }}/curl-curl-{{ curl_version }}'

  # user: vagrant
  remote_user: vagrant
  sudo: yes

  tasks:

  - name: Ensure required packages and installed and up to date - pt1
    yum: pkg={{ item }} state=present
    with_items:
      - make
      - gcc
      - etc...

  # Lots more yum tasks in here

  - name: Ensure CURL source downloaded
    get_url: url={{ curl_url }} dest=/home/vagrant/curl-{{ curl_version }}.tar

  - name: Extract CURL source
    command: tar -zxf {{ home }}/curl-{{ curl_version }}.tar creates={{ curl_dir }}

  - name: Copy ssh patch over
    copy: src=./files/ssh.c.patch dest={{ home }}/ssh.c.patch

  - name: Patch CURL with openssl
    shell: patch -t {{ curl_dir }}/lib/ssh.c {{ home }}/ssh.c.patch chdir={{ curl_dir }}/lib
    when: path_file_result.changed

  - name: Build CURL with openssl
    command: 'chdir={{ curl_dir }} "{{ item }}"'
    with_items:
      - ./buildconf
      - ./configure --with-gssapi --with-libidn --with-libssh2 --prefix=/usr --without-nss
      - make
      - make install
      - ldconfig

Vagrant 运行良好，并且 Ansible 剧本成功运行，直到最后一个任务“使用 openssl 构建 CURL” - 该任务失败，如下所示：

FATAL: all hosts have already failed -- aborting

因此，该./buildconf步骤有效，但该./configure --with-gssapi --with-libidn --with-libssh2 --prefix=/usr --without-nss步骤似乎失败了[Errno 2] No such file or directory。我推测这是因为它试图将整个字符串像单个命令一样运行？

如果我将其改为使用shell而不是command，我会得到以下结果：

failed: [default] => (item=./configure --with-gssapi --with-libidn --with-libssh2 --prefix=/usr --without-nss) => {"changed": true, "cmd": " \"./configure --with-gssapi --with-libidn --with-libssh2 --prefix=/usr --without-nss\" ", "delta": "0:00:00.001171", "end": "2014-02-07 02:31:34.862373", "item": "./configure --with-gssapi --with-libidn --with-libssh2 --prefix=/usr --without-nss", "rc": 127, "start": "2014-02-07 02:31:34.861202"}
stderr: /bin/sh: ./configure --with-gssapi --with-libidn --with-libssh2 --prefix=/usr --without-nss: No such file or directory

我已经验证了到目前为止的所有任务都有效，并且文件已下载并提取到预期的位置，并且补丁有效（看这里）。

任务失败后（或者您将其注释掉），如果您通过 SSH 进入正在配置的 VM，并自行运行所有相同的构建步骤 - 使用剧本中的精确值，它就可以起作用。

我对 Ansible 还不太熟悉，我不确定为什么它不起作用？我做错了什么？configure如果这是问题所在，是否有某种方法可以以不同的方式格式化或引用该命令，以便正确解释它？我应该使用raw它吗？还是别的什么？

解决办法是改变这一点：

shell: 'chdir={{ curl_dir }} "{{ item }}"'

更改为：

shell: "{{ item }}"
args:
  chdir: "{{ curl_dir }}"

这shell 模块的文档现在解决了格式化中的这个棘手问题。完整的工作构建任务目前如下所示：

- name: Build CURL with openssl
  shell: "{{ item }}"
  args:
    chdir: "{{ curl_dir }}"
  with_items:
    - ./buildconf
    - ./configure --with-gssapi --with-libidn --with-libssh2 --prefix=/usr --without-nss
    - make
    - make install
    - ldconfig
