导入错误：无法导入名称 '_ColumnEntity' Ubuntu20.10

问题描述

pip install apache-superset

请帮帮我，我长期以来一直面临这个错误

解决方法

您已经安装了 SQLAlchemy 1.4.0。 SQLAlchemy-utils 目前与 SQLAlchemy > 1.4.0 不兼容。解决方案是将 SQLAlchemy 降级到 1.3.23。

pip install SQLAlchemy==1.3.23

有关详细信息，请参阅 Temporarily require sqlalchemy <1.4.0 to make compatible with sqlalchemy-utils。
