Ansible 命令总是显示 SETUPTOOLS 将停止工作警告

Question

ansible 命令总是在下面打印警告：

/usr/local/lib/python2.7/dist-packages/pkg_resources/py2_warn.py:22: UserWarning: Setuptools will stop working on Python 2
************************************************************
You are running Setuptools on Python 2, which is no longer
supported and
>>> SETUPTOOLS WILL STOP WORKING <<<
in a subsequent release (no sooner than 2020-04-20).
Please ensure you are installing
Setuptools using pip 9.x or later or pin to `setuptools<45`
in your environment.
If you have done those things and are still encountering
this message, please comment in
https://github.com/pypa/setuptools/issues/1458
about the steps that led to this unsupported combination.
************************************************************
  sys.version_info < (3,) and warnings.warn(pre + "*" * 60 + msg + "*" * 60)

系统信息：ubuntu 16.04

安装方法：apt-get install ansible

我怎样才能摆脱这个警告？

提示：ansible 似乎使用/usr/bin/python，这是 ubuntu 环境中默认的python2.7。

Answer 1

又快又脏的方式：

编辑/usr/bin/ansible

添加代码：

import warnings
warnings.filterwarnings("ignore")

但是有没有更好的方法让ansible使用python3环境？

更好的方法

1. 使用pyenv或其他工具安装python3

2. 确保运行 /usr/bin/env python 运行 python3

3. 编辑/usr/bin/ansible

#!/usr/bin/python -> #!/usr/bin/env python

4. 使用pip install ansble 安装缺少的包。

否则会显示ansible module not found 错误。
