我试图将web2py连接到我的本地Oracle数据库，安装了下面的程序 cx_Oracle 从pip3安装到 Oracle即时客户端.
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')
但得到这个错误。
<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，我想把web2py连接到我的本地Oracle DB，从pip3安装了cx_Oracle，并安装了Oracle Instant Client。
添加了 /usr/lib/oracle/19.6/client64/lib 在 ld.so.conf 文件。
#vim /etc/ld.so.conf
/usr/lib/oracle/19.6/client64/lib
然后：sudo ldconfig
