ModuleNotFoundError:没有名为“airflow.providers.slack”气流2.0 (MWAA)的模块

Question

我正在使用气流2.0，并已通过requirements.txt在MWAA中安装了松弛模块。我已经安装了所有下面的软件包，但是它仍然说没有找到软件包。

  ModuleNotFoundError: No module named 'airflow.providers.slack'.

但它仍然给我一个错误说模块找不到。该怎么办？

Answer 1

我发现的解决方案是在requirements.txt顶部使用约束，正如Andrew (https://raw.githubusercontent.com/apache/airflow/constraints-2.2.2/constraints-3.7.txt)所回答的那样，并确认所有依赖项都已正确安装。一个折旧后的包名阻止了我安装airflow.providers.slack包。您可以通过本指南检查任何故障，并正确地重命名您的包：https://docs.aws.amazon.com/mwaa/latest/userguide/working-dags-dependencies.html#working-dags-dependencies-logs。

Answer 2

默认情况下，MWAA被限制为将版本3.0.0用于包apache-airflow-providers-slack。如果在4.2.3中指定requirements.txt版本，则不会安装它(错误日志应该在CloudWatch中可用)。您将不得不降级到3.0.0版本。

(constraints.txt)

或

将约束文件添加到requirements.txt顶部，以使用apache-airflow-providers-slack的版本4.2.3。

将Apache气流v2环境的约束文件添加到requirements.txt文件的顶部。

--constraint "https://raw.githubusercontent.com/apache/airflow/constraints-main/constraints-3.7.txt"

使用PyPi.org需求文件格式(MWAA)安装Python依赖项

约束文件(气流)
