How resolve WARN when run ansible: [WARNING]: Skipping plugin as it seems to be invalid?

Question

当我运行 ansible 命令时，如下所示：

ansible -i host all -m ping

我收到以下警告：

[WARNING]: Skipping plugin (/usr/lib/python2.7/dist-packages/ansible/plugins/callback/foreman.py) as it seems to be invalid: from_buffer() cannot return the address of the raw string
within a str or unicode or bytearray object
[WARNING]: Skipping plugin (/usr/lib/python2.7/dist-packages/ansible/plugins/callback/grafana_annotations.py) as it seems to be invalid: from_buffer() cannot return the address of the

为什么会发生这种情况？我该如何消除此警告？

服务器参数：
ansible 版本 - 2.9
操作系统版本 - Ubuntu 16.04

这看起来像是 Python 2 的弃用。

ansible --version

如果你得到

python version = 2.x.x (…)

您应该将 ansible 运行时更改为 Python 3。

更改 ansible 运行时相当复杂，更安全的做法是将操作系统升级到仅支持 Python 3 的版本。但是如果你需要使用任何其他依赖 Python2 的软件，这也可能很困难。
