Ansible无法找到requirements.txt

Question

我的目录结构是这样

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

的main.yml

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

内容，但，当我尝试提供的流浪盒使用命令vagrant up --provision从项目根。错误日志显示ansible无法找到pip-requirements.txt放在files/

这里面是错误日志

    "cmd": "/home/vagrant/venvs/cv/bin/pip2 install -r ../files/pip-requirements.txt",

}

pip模块预计requirements文件是在目标框：

pip需求文件的路径，对远程系统应该是本地的。如果使用chdir选项，文件可以被指定为相对路径。

因此，如果您的供应过程未将您的本地文件夹复制/链接到流浪盒中，则没有pip-requirements.txt可用。
