【问题描述】：
我正在使用 Kenneth Ritz 的记录库连接到 Oracle。
db = records.Database('oracle://scott/tiger@localhost:1521/orcl')
但它总是抛出这个错误
DatabaseError: (cx_Oracle.DatabaseError)
ORA-12545: Connect failed because target host
or object does not exist.
但是，通过 SQL Plus 连接就可以了
sqlplus scott/tiger@localhost/orcl:1521
SQL*Plus: Release 12.1.0.1.0 Production on Sat Mar 11 17:29:19 2017

Connected to:
Oracle Database 12c Enterprise Edition Release 12.1.0.1.0 - 64bit Production
With the Partitioning, OLAP, Advanced Analytics and Real Application Testing options
SQL>
有趣的观察
db = cx_Oracle.connect('scott/tiger@localhost:1521/orcl') **<--Works**
db.version
'12.1.0.1.0'
db = records.Database('oracle+cx_oracle://scott/tiger@localhost:1521/orcl')
doesn't work
知道我在这里做错了什么吗？
