安装使用 superset

安装 superset

创建虚拟环境：

python -m venv msuperset

激活虚拟环境：

cd msuperset
source bin/activate

安装 superset

pip install superset

如果遇到报错：

  Running setup.py install for python-geohash ... error
    Complete output from command /root/code/python/msuperset/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-szdbf0qe/python-geohash/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-omybv2pz-record/install-record.txt --single-version-externally-managed --compile --install-headers /root/code/python/msuperset/include/site/python3.6/python-geohash:

需要安装 gcc-c++：

yum install gcc-c++

装完 gcc-c++ 后，再执行 pip install superset 应该就没问题了。

配置 superset

创建管理员用户

fabmanager create-admin --app superset

执行的时候会有这么一行提示：

fabmanager is going to be deprecated in 2.2.X, you can use the same commands on the improved 'flask fab <command>'

这是一个新的用法了，还没有研究

接着会让你输入用户名（username）、Fist Name、Last Name、邮箱地址、密码、重复密码。

如果遇到以下错误：

Was unable to import superset Error: cannot import name '_maybe_box_datetimelike'

原因是 pandas （在安装 superset 时会做为依赖被安装上）版本太高，需要卸载，再安装低版本的 pandas。

pip install pandas==0.23.4

参考https://blog.csdn.net/kongxx/article/details/89006787

然后重新执行创建管理员用户的命令：

fabmanager create-admin --app superset

初始化数据库

superset db upgrade

如果遇到错误：

...
  File "/root/code/python/msuperset/lib/python3.6/site-packages/sqlalchemy/orm/query.py", line 2572, in _join_determine_implicit_left_side
    "Can't determine which FROM clause to join "
sqlalchemy.exc.InvalidRequestError: Can't determine which FROM clause to join from, there are multiple FROMS which can join to this entity. Try adding an explicit ON clause to help resolve the ambiguity.

说明 sqlalchemy 版本太高了，要降级 sqlalchemy：

pip install sqlalchemy==1.2.18

参考https://github.com/apache/incubator-superset/issues/6977

载入测试数据

superset load_examples

初始化角色和权限

superset init

启动服务

端口号 8088，使用 -p 更改端口号

superset runserver

然后在浏览器中打开 http://localhsot:8088 就可以看到 superset 了

添加 mysql 数据源时出错

提示

ModuleNotFoundError: No module named 'MySQLdb'

因为 MySQLdb 是 python2 的产品。可使用 mysqlclient 方式代替。要安装 mysqlclient：

先安装需要用到的系统依赖：

Ubuntu 下：

sudo apt-get install python3-dev libmysqlclient-dev

CentOS 下：

yum install python-devel mysql-devel

然后安装 mysqlclient：

pip install mysqlclient

安装 libsasl2-dev

ubuntu

apt-get install libsasl2-dev

centos

yum -y install cyrus-sasl cyrus-sasl-devel cyrus-sasl-lib
