手动卸载冲突包six 1.5.2

有可能Use Python 3 on the managed machines with commands and playbooks。如果您认为这将解决冲突，请在清单中设置变量ansible_python_interpreter

ansible_python_interpreter=/usr/bin/python3

应自动选择pip版本。该问题由pip报告。见source code

- name: install python requirements
  pip: requirements=/vagrant/requirements.txt

皮普说：

By default, it uses the pip version for the Ansible Python interpreter. For example, pip3 on python 3, and pip2 or pip on python 2.
