python-3.x - ImportError：没有名为 influxdb 的模块。无法导入所需的 Python 库 (influxdb)
问题描述
我在使用“influxdb_database”模块通过 ansible 管理 influxdb 时遇到问题。即使它打印出有关 python 依赖的错误，但只有当运行 ansible playbook 的容器在来自 influxdb 托管的 diff VM 上运行时，它才会失败。我从 docker 容器运行 ansible playbook，如果我在安装了 influxdb 的主机上运行容器，它工作正常 - 它正在管理创建数据库。但是，当相同的容器（从与前面提到的相同的映像创建）在与 influxdb 托管的虚拟机不同的虚拟机上运行时，它会失败，并在下面粘贴错误。所以我现在对关于 python 依赖的错误感到困惑，不明白问题出在哪里。

解决方案
听起来你和我处理同样的问题。我正在努力找出问题所在，然后我阅读了要求并看到了这一点。我正在使用比这个模块支持的更新版本的 influxdb，所以我得到了和你一样的错误
要求 执行此模块的主机需要以下要求。
蟒蛇> = 2.6
涌入数据库 >= 0.9 & <= 1.2.4

更新：
我已经能够找到一种使用 api 而不是模块与 influx DB 交互的方法，因为它们不起作用。这涉及编辑 influxdb.conf 以启用使用 API
# modifying the influxdb.conf is required to be able to use the influxDB API
