安裝使用 superset

安裝 superset

創建虛擬環境：

python -m venv msuperset

激活虛擬環境：

cd msuperset
source bin/activate

安裝 superset

pip install superset

如果遇到報錯：

需要安裝 gcc-c++：

yum install gcc-c++

裝完 gcc-c++ 后，再執行 pip install superset 應該就沒問題了。

配置 superset

創建管理員用戶

fabmanager create-admin --app superset

執行的時候會有這么一行提示：

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

這是一個新的用法了，還沒有研究

接着會讓你輸入用戶名（username）、Fist Name、Last Name、郵箱地址、密碼、重復密碼。

如果遇到以下錯誤：

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

原因是 pandas （在安裝 superset 時會做為依賴被安裝上）版本太高，需要卸載，再安裝低版本的 pandas。

pip install pandas==0.23.4

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

然后重新執行創建管理員用戶的命令：

fabmanager create-admin --app superset

初始化數據庫

superset db upgrade

如果遇到錯誤：

...
  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.

說明 sqlalchemy 版本太高了，要降級 sqlalchemy：

pip install sqlalchemy==1.2.18

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

載入測試數據

superset load_examples

初始化角色和權限

superset init

啟動服務

端口號 8088，使用 -p 更改端口號

superset runserver

然后在瀏覽器中打開 http://localhsot:8088 就可以看到 superset 了

添加 mysql 數據源時出錯

提示

ModuleNotFoundError: No module named 'MySQLdb'

因為 MySQLdb 是 python2 的產品。可使用 mysqlclient 方式代替。要安裝 mysqlclient：

先安裝需要用到的系統依賴：

Ubuntu 下：

sudo apt-get install python3-dev libmysqlclient-dev

CentOS 下：

yum install python-devel mysql-devel

然后安裝 mysqlclient：

pip install mysqlclient

安裝 libsasl2-dev

ubuntu

apt-get install libsasl2-dev

centos

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