python - Web2py - Oracle 连接失败

Question

我正在尝试将 web2py 连接到我的本地 Oracle DB，cx_Oracle从 pip3 安装并安装Oracle Instant Client。

echo $LD_LIBRARY_PATH
/usr/lib/oracle/19.6/client64/lib:

Web2py 版本Version 2.19.1-stable+timestamp.2020.03.21.13.06.49。

我的 db.py，文件

db = DAL('oracle://username/password@test')

但收到此错误：

<class 'RuntimeError'> Failure to connect, tried 5 times: Traceback (most recent call last): File "/home/user/project/web2py/gluon/packages/dal/pydal/base.py", line 507, in __init__ self._adapter = adapter(**kwargs) File "/home/user/project/web2py/gluon/packages/dal/pydal/adapters/__init__.py", line 41, in __call__ obj = super(AdapterMeta, cls).__call__(*args, **kwargs) File "/home/user/project/web2py/gluon/packages/dal/pydal/adapters/base.py", line 417, in __init__ super(SQLAdapter, self).__init__(*args, **kwargs) File "/home/user/project/web2py/gluon/packages/dal/pydal/adapters/base.py", line 85, in __init__ self.find_driver() File "/home/user/project/web2py/gluon/packages/dal/pydal/adapters/base.py", line 134, in find_driver "No driver of supported ones %s is available" % str(self.drivers) RuntimeError: No driver of supported ones ('cx_Oracle',) is available 

谢谢。

/usr/lib/oracle/19.6/client64/lib在ld.so.conf文件中添加：

#vim /etc/ld.so.conf
/usr/lib/oracle/19.6/client64/lib

然后： sudo ldconfig
