Question

我正在尝试使用Ansible安装气流，所以我有这个命令

- pip
  name: apache-airflow[s3, postgres]
  version: 1.9.0

但是这个错误就失败了：

pip2安装 apache-airflow [s3 == 1.9.0 postgres == 1.9.0 celery] == 1.9.0 无效要求：'apache-airflow [s3 == 1.9.0' Traceback（最近一次调用最后一次）：在from_line中输入文件“/usr/lib/python2.7/site-packages/pip/_internal/req/req_install.py”，第252行 req =要求（要求）在 init 中输入文件“/usr/lib/python2.7/site-packages/pip/_vendor/packaging/requirements.py”，第97行 requirements_string [e.loc：e.loc + 8]）） InvalidRequirement：无效的需求，解析错误在''[ s3 == 1.9 '“

因此它认为该版本适用于每个子包，但它不适用。它应该尝试安装

apache-airflow[s3, postgres]==1.9.0

在Ansible中安装子包的方法是什么？

根据这个github issue，您应该使用以下语法：

  - name: install with pip
    pip:
      name: 
        - 'apache-airflow[s3,postgres]'
      version: 1.9.0

请注意[s3,postgres]中的空格字符已被删除。

更新：当有空格字符时，我会得到与OP问题相同的行为，这就是为什么我建议将其删除（因为github问题也是如此）：

错误当有空格字符时，[s3，postgres] ：

Ansible：用pip安装python子包
