Question

我正在Ansible中运行此pip命令

- name: Install airflow
  pip: "name=apache-airflow[async,postgres] state=present"
  environment:
     SLUGIFY_USES_TEXT_UNIDECODE: yes
     AIRFLOW_GPL_UNIDECODE: yes

但是我收到一个错误

Invalid requirement: 'apache-airflow[async'\nTraceback (most recent call last):\n  File \"/usr/local/lib/python2.7/dist-packages/pip/req/req_install.py\", line 82, in __init__\n    req = Requirement(req)\n  File \"/usr/local/lib/python2.7/dist-packages/pip/_vendor/packaging/requirements.py\", line 96, in __init__\n    requirement_string[e.loc:e.loc + 8]))\nInvalidRequirement: Invalid requirement, parse error at \"'[async'\"

我认为通过引用点行，不会尝试分隔逗号的任何一侧。 Ansible中有没有一种方法可以逃脱逗号或以其他方式将参数列表传递到Airflow安装行中

Answer 1

分离命令似乎可行。

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

- name: Airflow with postgres
  pip:
     name: apache-airflow[postgres]
  environment:
     SLUGIFY_USES_TEXT_UNIDECODE: yes
     AIRFLOW_GPL_UNIDECODE: yes

Answer 2

只需用'\'对其进行转义。虽然没有测试。希望它能起作用。

- name: Install airflow
  pip: "name=apache-airflow[async\\,postgres] state=present"
  environment:
     SLUGIFY_USES_TEXT_UNIDECODE: yes
     AIRFLOW_GPL_UNIDECODE: yes
