“import sqlitebck”导致“module”对象没有属性“Connection”

Question

升级到sqlitebck ver后。1.3：

Traceback (most recent call last):
  File "/opt/rh/python27/root/usr/lib64/python2.7/runpy.py", line 174, in _run_module_as_main
    "__main__", fname, loader, pkg_name)
  File "/opt/rh/python27/root/usr/lib64/python2.7/runpy.py", line 72, in _run_code
    exec code in run_globals
  File "/opt/IBM/InformationServer/Server/DSEngine/bin/ISMD-emeaprd.py/__main__.py", line 38, in <module>
AttributeError: 'module' object has no attribute 'Connection'
/var/tmp/sclPqKpVb: line 8:  2032 Segmentation fault      (core dumped) python /opt/IBM/InformationServer/Server/DSEngine/bin/ISMD-emeaprd.py

第38行是：

我在RHEL 6.9上编译的-没有错误：

这是表示“sqlitebck”模块的文件：

[root@ lib.linux-x86_64-2.7]# ll

-rwxr-xr-x 1 root root 24789 Nov  5 11:13 sqlitebck.so

安装过程也很好：

python setup.py install
running install
running build
running build_ext
running install_lib

Writing /opt/rh/python27/root/usr/lib64/python2.7/site-packages/sqlitebck-1.3-py2.7.egg-info

编辑1:在交互模式下尝试：

bash-4.1$ python
Python 2.7.13 (default, Feb  8 2017, 06:30:30)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-16)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>
>>>
>>> import sqlitebck
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'Connection'

在我看来，在这种情况下可能遇到了一个bug，但我想确定我的理解是正确的，或者我遗漏了一些东西。在

谢谢你们的时间，伙计们！在

Answer 2

1）下载了最新的SQLite-ver。3.21（sqlite-autoconf-3210000。焦油gz). 在

2）编译安装。在

[root@localhost sqlitebck]# sqlite3 -version
3.21.0 2017-10-24 18:55:49 1a584e499906b5c87ec7d43d4abce641fdf017c42125b083109bc77c4de48827

3）确保在会话中链接其库，并使其包含文件（'.h'文件）可用，然后重新编译“sqlitebck”版本。1.3条。在

它现在起作用了。在
