【问题描述】：
我已在此处概述的 AWS EC2 实例上安装了 Apache Superset - https://superset.apache.org/docs/installation/installing-superset-from-scratch。
当我运行superset load_examples 命令时，我收到以下错误。这在我的本地计算机上运行良好，但由于某种原因在 EC2 上不起作用。错误提示“变量太多”，但只有 7 个变量。
SQL Alchemy 版本如下：
SQLAlchemy==1.3.22
SQLAlchemy-Utils==0.36.8
错误日志：
Traceback (most recent call last):
File "/home/ec2-user/superset/venv/lib64/python3.7/site-packages/sqlalchemy/engine/base.py", line 1277, in _execute_context

sqlite3.OperationalError: too many SQL variables
The above exception was the direct cause of the following exception:
