superset db upgrade报错记录

报错1

(superset) [hyj@hadoop102 ~]$ superset db upgrade

    from markupsafe import soft_unicode
ImportError: cannot import name 'soft_unicode' from 'markupsafe' (/opt/module/miniconda3/envs/superset/lib/python3.7/site-packages/markupsafe/__init__.py)

解决方法:

1. 查看markupsafe这个包是否存在

(superset) [hyj@hadoop102 ~]$ pip show markupsafe
Name: MarkupSafe
Version: 2.1.2

2. 下载2.0.1版本的markupsafe (pip会帮我们卸载之前版本的并下载2.0.1版本的markupsafe)

(superset) [hyj@hadoop102 ~]$ pip install markupsafe==2.0.1

报错2

(superset) [hyj@hadoop102 ~]$ superset db upgrade

    for ep in importlib_metadata.entry_points().get(namespace, [])
AttributeError: 'EntryPoints' object has no attribute 'get'

解决方法:

(superset) [hyj@hadoop102 ~]$ pip install importlib-metadata==4.13.0

报错3

(superset) [hyj@hadoop102 ~]$ superset db upgrade

 from typing import List, Optional, TypedDict, Union
ImportError: cannot import name 'TypedDict' from 'typing' (/opt/module/miniconda3/envs/superset/lib/python3.7/typing.py)

• 这个错误通常是由于Python版本过低导致的,因为 TypedDict 是在Python3.8中引入的。
• 如果你使用的是Python3.7或更早的版本,那么就会出现这个问题。
• 要解决这个问题,可以将Python版本升级到3.8或者更高的版本。另外,你也可以使用第三方库typing_extensions来实现类似的功能。

(superset) [hyj@hadoop102 ~]$ python -V
Python 3.7.13
(superset) [hyj@hadoop102 ~]$ conda deactivate
(base) [hyj@hadoop102 ~]$ conda info --envs
# conda environments:
#
base                  *  /opt/module/miniconda3
superset                 /opt/module/miniconda3/envs/superset

(base) [hyj@hadoop102 ~]$ conda remove -n superset --all
(base) [hyj@hadoop102 ~]$ conda create --name superset python=3.8
(base) [hyj@hadoop102 ~]$  conda activate superset

(superset) [hyj@hadoop102 ~]$ superset db upgrade

re.compile(r"'(''|\\\\|\\|[^'])*'", sqlparse.keywords.FLAGS).match,
AttributeError: module 'sqlparse.keywords' has no attribute 'FLAGS'

解决方法:

(superset) [hyj@hadoop102 ~]$ pip install sqlparse=='0.4.3'

报错5

(superset) [hyj@hadoop102 ~]$ superset db upgrade

Error: Could not locate a Flask application. 
You did not provide the "FLASK_APP" environment variable, and a "wsgi.py" or "app.py" module was not found in the current directory.

解决方法:

(superset) [hyj@hadoop102 ~]$  export FLASK_APP=superset

Refusing to start due to insecure SECRET_KEY

解决方法:

1. 进入到miniconda3的安装路径下的envs/superset/lib/python3.8/目录

(superset) [hyj@hadoop102 ~]$ cd /opt/module/miniconda3/envs/superset/lib/python3.8/

2. 创建superset_config.py

(superset) [hyj@hadoop102 python3.8]$ vim superset_config.py

3. 添加如下内容

# Superset specific config
# SS 相关的配置
# 行数限制 5000 行
ROW_LIMIT = 5000
 
# 网站服务器端口 8088
SUPERSET_WEBSERVER_PORT = 8088

# and encrypting sensitive information on the database
# Make sure you are changing this key for your deployment with a strong key.
# You can generate a strong key using `openssl rand -base64 42`
# Flask 应用构建器配置
# 应用密钥用来保护会话 cookie 的安全签名
# 并且用来加密数据库中的敏感信息
# 请确保在你的部署环境选择一个强密钥
# 可以使用命令 openssl rand -base64 42 来生成一个强密钥
 
SECRET_KEY = "ZT2uRVAMPKpVkHM/QA1QiQlMuUgAi7LLo160AHA99aihEjp03m1HR6Kg" 
 
# The SQLAlchemy connection string to your database backend

# SQLAlchemy 数据库连接信息
# 这个连接信息定义了 SS 元数据库的路径（切片、连接、表、数据面板等等）

WTF_CSRF_TIME_LIMIT = 60 * 60 * 24 * 365
 
# Set this API key to enable Mapbox visualizations

MAPBOX_API_KEY = ''

• 用命令 openssl rand -base64 42 来生成一个强密钥
• [hyj@hadoop102 ~]$ openssl rand -base64 42
  4xPjBius42o5Y/pbgRmkjKZ3im5CeHcRXM93TWm+FboEJOll0XMMgDRW
• 所以SECRET_KEY =“4xPjBius42o5Y/pbgRmkjKZ3im5CeHcRXM93TWm+FboEJOll0XMMgDRW”
