意外异常:调用ansible2时未定义名称"basestring"

Question

我正在尝试执行ansible2 commnads ...

当我做:

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

我明白了:

意外的异常:名称'basestring'未定义完整的回溯是:

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

这是ansible --version:

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

这是 python --version

Python 3.4.3

Answer 1

低于2.5版的Ansible在控制主机上需要Python 2.6或2.7:控制机器要求

basestring在Python 3中不再可用.来自Python 3.0中的新功能:

内置的basestring抽象类型已被删除.请str改用.该str和bytes类型没有足够的功能共同保证一个共享的基类.该2to3工具(见下文)取代的每次出现basestring用str.

Answer 2

basetring在Python 3中不可用:

对于python 2.x和3.x,可以使用以下方法修复此问题:

try:
  basestring
except NameError:
  basestring = str
