你好，

我有一个两部分的问题。

第一部分： 我正在尝试从下载剧本并执行它的 python 脚本中执行剧本。我知道该剧本有效，因为我已经对其进行了测试。但是，当我尝试使用 python 代码执行剧本时，我得到一个无属性错误'set_playbook_basedir'，不太确定这是从哪里来的。这是完整的错误输出。

                               check=True)
# running the playbook
pr = pb.run()

# print the summary of results for each host
#print json.dumps(pr, sort_keys=True, indent=4, separators=(',', ': '))

第二个问题是：

该脚本实际上是作为 base64 编码的 aws 用户数据及其执行传递的，但它似乎没有识别出它是 python。这是 cloud-init-output.log

Complete!

我无法重现您的问题，但我最好的猜测是：

1）您需要使用 Inventory 对象而不是字符串来初始化您的剧本：

from ansible.inventory import Inventory
pb = PlayBook(playbook = full_path,
              stats = stats,
              callbacks = playbook_cb,
              runner_callbacks = runner_cb,
              inventory = Inventory(["localhost"]),
              check=True)

2）您的python脚本需要以bash为前缀，表明它应该由python执行。只需将以下shebang放在 python 脚本的顶部：

#! /usr/bin/env python

或者，您可以使用以下命令运行脚本：

python /var/lib/cloud/instance/scripts/part-001

而不仅仅是：

/var/lib/cloud/instance/scripts/part-001
