做艺术字的网站,网页开发需要学什么,网页设计师常用网站,做网站南宁折腾完了hana和sqlserver数据库的连接，开始折腾oracle数据库连接 1.requirements-local.txt配置 尝试在requirements-local.txt中设置，结果容器弄瘫痪了，拉不起来了，只要又去掉修改 rootNocobase:/usr/superset/superset/docker# …

折腾完了hana和sqlserver数据库的连接，开始折腾oracle数据库连接
1.requirements-local.txt配置
尝试在requirements-local.txt中设置，结果容器弄瘫痪了，拉不起来了，只要又去掉修改
root@Nocobase:/usr/superset/superset/docker# echo "cx_Oracle">> requirements-local.txt

前面配置sql server只是不能连接，现在连驱动安装都不给脸了。只能手动了。
2.进入到容器中，安装cx_Oracle
root@Nocoly:/superset_data/superset/docker# docker exec -it superset_app bash
root@3da2ba740404:/app# pip install cx_Oracle

3.安装pyproject

既然需要pyproject，我们就安装pyproject
root@3da2ba740404:/app# pip install pyproject

4.再次安装cx_Oracle

pyproject安装成功再安装cx_Oracle，但是还是一样的错误
root@3da2ba740404:/app# pip install cx_Oracle

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for cx_Oracle
Failed to build cx_Oracle
ERROR: Could not build wheels for cx_Oracle, which is required to install pyproject.toml-based projects

查看pip,pyproject是安装成功的。
root@3da2ba740404:/app# pip freeze
Jinja2==3.1.6
MarkupSafe==3.0.2
pymssql==2.3.2
pyproject==1.3.1
uv==0.6.9
root@3da2ba740404:/app#


5.解决gcc

错误提示中还和gcc有关系。
root@Nocoly:/superset_data/superset/docker# docker exec -it superset_app bash

安装成功。
7.配置连接,测试失败
使用连接串oracle://system:CNpass2019@172.168.0.16:1521/?service_name=orcl
配置测试时提示错误：
ERROR: Could not load database driver: OracleEngineSpec看起来还是无法连接oracle
superset_app          |   File "/app/.venv/lib/python3.11/site-packages/sqlalchemy/dialects/oracle/cx_oracle.py", line 1068, in dbapi
superset_app          |     import cx_Oracle
superset_app          | ModuleNotFoundError: No module named 'cx_Oracle'

再次修改requirements-local.txt ，启动的时候一直报错，还是提示gcc相关的错误。见鬼。

8.安装oracle client
--下载
找到cx_oracle的网站，https://cx-oracle.readthedocs.io/en/latest/user_guide/installation.html#install-cx-oracle，这个里面有一大段话：
Using cx_Oracle requires Oracle Client libraries to be installed. These provide the necessary network connectivity allowing cx_Oracle to access an Oracle Database instance.
于是转头开始安装oracle client.
在Oracle网站上找到client下载地址，wget下载：
root@4e7cbd9d89c1:/app# mkdir /opt/oracle
root@4e7cbd9d89c1:/app# cd /opt/oracle
root@4e7cbd9d89c1:/opt/oracle# wget https://download.oracle.com/otn/linux/instantclient/122010/instantclient-basic-linux.x64-12.2.0.1.0.zip

文件明明存在，但是解压不了，原因是因为oracle下载需要登录。在宿主机上登录oracle下载后，拷贝到docker中。

9.配置连接，失败
还是同样的错误：ModuleNotFoundError: No module named 'cx_oracle'
root@4e7cbd9d89c1:/app# python3
Python 3.11.11 (main, Apr  8 2025, 01:39:46) [GCC 12.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import cx_oracle
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'cx_oracle'

oracle client已经安装了，cx_oracle已经安装了，为什么还是提示“No module named 'cx_oracle”？环境变量问题？
 

root@4e7cbd9d89c1:/app# python -m site
sys.path = [
    '/app',
    '/app/pythonpath',
    '/app/docker/pythonpath_dev',
    '/usr/local/lib/python311.zip',
    '/usr/local/lib/python3.11',
    '/usr/local/lib/python3.11/lib-dynload',
    '/app/.venv/lib/python3.11/site-packages',
]
USER_BASE: '/app/superset_home/.local' (doesn't exist)
USER_SITE: '/app/superset_home/.local/lib/python3.11/site-packages' (doesn't exist)
ENABLE_USER_SITE: False
root@4e7cbd9d89c1:/app# cd /app/.venv/lib/python3.11/site-packages
这个目录下真的找不到cx_oracle,再安装一次看看
root@4e7cbd9d89c1:/app#  pip3 install cx_oracle
Requirement already satisfied: cx_oracle in /usr/local/lib/python3.11/site-packages (8.3.0)
WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager, possibly rendering your system unusable. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv. Use the --root-user-action option if you know what you are doing and want to suppress this warning.
安装路径在/usr/local/lib/python3.11/site-packages (8.3.0)，而sys.path 中并没有此路径，那我添加路径再测试。

>>> sys.path.append('/usr/local/lib/python3.11/site-packages')
>>> import cx_oracle
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

结果还是同样的错误，python里面测试如此，superset里面肯定没戏，彻底卡住了，失败！我想换条路走走了。
