安装superset遇到的坑

实验环境：ubuntu16.04
python环境: 3.6.7

安装参考：https://superset.incubator.apache.org/installation.html

特别提醒:
python3.6-dev 一定要安装

1. "Was unable to import superset Error: cannot import name '_maybe_box_datetimelike'"

(venv1) root@VM-220-19-ubuntu:/data# fabmanager create-admin --app superset
Username [admin]: admin      
User first name [admin]: admin
User last name [user]: admin
Email [admin@fab.org]: admin@aldwx.com
Password:
Repeat for confirmation:
Was unable to import superset Error: cannot import name '_maybe_box_datetimelike'

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

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

3. sqlalchemy.exc.InvalidRequestError: Can't determine which FROM clause to join from, there are multiple FROMS which cto help resolve the ambiguity.

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
