Amazon 中的 Airflow initdb 失败 Linux

Question

我正在尝试在 EC2 (Amazon Linux) 中安装 Airflow，但 "airflow initdb" 失败并出现以下错误：

$ AIRFLOW_HOME=/var/lib/airflow airflow initdb
[2019-09-07 20:51:32,416] {__init__.py:51} INFO - Using executor SequentialExecutor
Traceback (most recent call last):

                                      ^
SyntaxError: invalid syntax

由于这是一个语法错误，我怀疑 marshmallow_sqlalchemy 和 SQLAlchemy 之间存在一些版本冲突。以下是他们的版本：

apache-airflow==1.10.5
Flask==1.1.1
Flask-SQLAlchemy==2.4.0
marshmallow==2.20.3
marshmallow-enum==1.5.1
marshmallow-sqlalchemy==0.19.0
SQLAlchemy==1.3.8

有什么想法吗？

Answer 1

看来 marshmallow-sqlalchemy 版本已升级，这就是您收到此错误的原因。卸载当前版本-

pip 卸载 marshmallow-sqlalchemy

并尝试安装以下版本，然后你就可以开始了。

pip install marshmallow-sqlalchemy==0.17.1

我也遇到过类似的问题，现在已经用同样的方法解决了。 希望对您有所帮助！
