努力打造剧本的安装气流（在virtualenv中的文件夹）。 Ansible不是的virtualenv环境中执行命令

Question

努力打造剧本可以在virtualenv中环境中安装Apache的气流。 Ansible不是的virtualenv文件夹内执行命令。下面是我的剧本和错误。

剧本内容： -

    - name: Active virtual Environment
      shell: source bin/activate
      args:
        chdir: "{{ directory }}"

    - name: Upgrade pip to latest version
      shell: pip install --upgrade pip

    - name: Execute export GPL
      shell: export AIRFLOW_GPL_UNIDECODE=yes

    - name: Execute export slugify
      shell: SLUGIFY_USES_TEXT_UNIDECODE=yes

    - name: Install airflow
      pip: name=apache-airflow state=present

Answer 1

任务是独立的，以便出口像AIRFLOW_GPL_UNIDECODE=yes变量不会在以下任务可用，如果你想传递的环境变量，使用关键字environment:在任务此方法将它传递

 - name: Install airflow
   pip: name=apache-airflow state=present
   environment:
     SLUGIFY_USES_TEXT_UNIDECODE: yes
     AIRFLOW_GPL_UNIDECODE: yes

（见https://docs.ansible.com/ansible/latest/user_guide/playbooks_environment.html）

Answer 2

画中画ansible模块virtuanlenv参数为好。文档：https://docs.ansible.com/ansible/latest/modules/pip_module.html

- name: Install airflow
   pip: name=apache-airflow state=present
   virtualenv: '{{ airflow_virtualenv }}'
   virtualenv_python: '{{ airflow_python_version }}'
   environment:
     SLUGIFY_USES_TEXT_UNIDECODE: yes
     AIRFLOW_GPL_UNIDECODE: yes
