意外异常：在调用ansible2时，名称'basestring'未定义

Question

我正在尝试执行ansible2命令。。。

当我这样做时：

ansible-playbook -vvv -i my/inventory my/playbook.yml

我得到：

Unexpected Exception: name 'basestring' is not defined the full traceback was:

Traceback (most recent call last):
  File "/usr/local/bin/ansible-playbook", line 85, in <module>
    sys.exit(cli.run())
  File "/usr/local/lib/python3.4/site-packages/ansible/cli/playbook.py", line 150, in run
    results = pbex.run()
  File "/usr/local/lib/python3.4/site-packages/ansible/executor/playbook_executor.py", line 87, in run
    self._tqm.load_callbacks()
  File "/usr/local/lib/python3.4/site-packages/ansible/executor/task_queue_manager.py", line 149, in load_callbacks
    elif isinstance(self._stdout_callback, basestring):
NameError: name 'basestring' is not defined

这里是ansible --version：

ansible 2.0.0.2
  config file = /etc/ansible/ansible.cfg
  configured module search path = Default w/o overrides

这里是python --version

Python 3.4.3

低于版本2.5的Ansible需要控制主机上的Python 2.6或2.7：Control Node Requirements

basestring在Python 3中不再可用。来自What’s New In Python 3.0：

The builtin basestring abstract type was removed. Use str instead. The str and bytes types don’t have functionality enough in common to warrant a shared base class. The 2to3 tool (see below) replaces every occurrence of basestring with str.
