解决方法
卸载当前pandas版本，安装pandas==0.23.4
(venv1) root@VM-220-19-ubuntu:/data# pip3 uninstall pandas
Uninstalling pandas-0.24.2:
Would remove:
/data/venv1/lib/python3.6/site-packages/pandas-0.24.2.dist-info/*
/data/venv1/lib/python3.6/site-packages/pandas/*
Proceed (y/n)? Y
Successfully uninstalled pandas-0.24.2

(Background on this error at: http://sqlalche.me/e/gkpj)
No user created an error occured
问题分析
报错提示唯一约束失败。因为创建的用户发生冲突
解决方法1
修改用户，指定其他用户为管理员
解决方法2
如果是新建数据库，可以重建。在此基础上如果是sqlite数据库，可以修改数据库文件名或删除数据库文件，让程序自动重建。
配置数据库的文件 /data/venv1/lib/python3.6/site-packages/superset/config.py
sqlite数据库默认在当前用户下 ~/.superset/superset.db

解决方法
安装sqlalchemy==1.2.18
pip install sqlalchemy==1.2.18 #当时用pip安装的，结果也没问题
