python - Ansible 库存脚本需要 requests 模块，我如何将包安装到 Ansible 本身？

问题描述

我正在使用一个 python 脚本，它从一个 rest api 中提取，然后以 JSON 格式构建并打印出一个清单。与此处的问题非常相似，如何使用包含主机信息的 json 文件作为 ansible 库存的输入

但是我的脚本需要请求从其余 api 中提取数据，但它看起来不像 Ansible 有这个包？

ansible-playbook -i host_wrapper.py gather_ios_facts.yml -k -vvv
...
/Users/alexw/ansible/host_wrapper.py did not meet yaml requirements, check plugin documentation if this is unexpected
 [WARNING]:  * Failed to parse /Users/alexw/ansible/host_wrapper.py with script plugin: Inventory script
(/Users/alexw/ansible/host_wrapper.py) had an execution error: Traceback (most recent call last):   File
"/Users/alexw/ansible/host_wrapper.py", line 2, in <module>     import requests, json ImportError: No module named
requests

  File "/usr/local/lib/python3.6/site-packages/ansible/plugins/inventory/script.py", line 114, in parse
    raise AnsibleError("Inventory script (%s) had an execution error: %s " % (path, err))

我的 host_wrapper 脚本的第一行

#!/usr/bin/env python
import requests, json
...

编辑：

我以为我会用 pip 安装它，但它仍然失败，输出如下：

解决方案

原来我的shebang指向没有安装模块的python 2.7。我的本地 python 命令默认设置为运行 3.6。

将我的 shebang 修改为指向 3.6，现在可以正确导入

#!/usr/local/bin/python3.6
import requests, json
