ubuntu - Ansible 无法找到 requirements.txt

Question

我的目录结构是这样的

$ tree
├── Vagrantfile
├── files
│   ├── cmake
│   ├── pip-requirements.txt
│   └── profile
└── tasks
    └── main.yml

main.yml的内容

---
- hosts: kurseve
  tasks:
      - name: Install pip
        pip:
          requirements: ../files/pip-requirements.txt
          virtualenv: /home/vagrant/venvs/cv
          virtualenv_python: python2.7

但是当我尝试使用命令 vagrant up --provision 配置 Vagrant 框时从项目根目录。错误日志显示 ansible 无法找到 pip-requirements.txt放在 files/里面

这是错误日志

    "changed": false,

    },

}

Answer 1

pip模块期望 requirements要在目标框上的文件:

The path to a pip requirements file, which should be local to the remote system. File can be specified as a relative path if using the chdir option.

因此，如果您的配置过程没有将您的本地文件夹复制/链接到 vagrant box，则没有 pip-requirements.txt可用的。
