Python 3.x 用于Python的IBM_DB包似乎没有IBM_DB.dll

免责声明： 我是Python的新手

在过去的几天里，我一直在尝试使用Python访问DB2数据库，但到目前为止，我的尝试没有成功

我已经通过执行以下命令安装了“ibm_db”包：pip install ibm_db，它似乎安装成功了。因此，当我尝试导入ibm_db时，不再出现“找不到ibm_db的模块”错误。此外，我还相应地设置了IBM_DB_HOME

但是，当我尝试执行以下代码时，我现在得到了这个错误： ImportError:导入ibm_db时DLL加载失败：找不到指定的模块

我已经爬过了互联网，看看我缺少了什么，发现我没有任何IBM_DB_DLL文件夹，也没有IBM_DB.DLL

如何获取这些文件

系统和安装详细信息：

Windows 10-64位

Python版本——win32上的Python 3.8.0[MSC v.1916 64位（AMD64）]——我不知道win32的含义。我从Python网站安装了这个版本（Windows x86-64可执行安装程序）

我还安装了“IBM DB2运行时客户机10.5fp8”

IBM\u DB\u HOME变量设置为：C:\Python\Lib\site packages

我能够用Python运行其他程序。但是，这是我第一次尝试连接到DB2

非常感谢您的任何帮助或意见

提前感谢,

甘尼什

def make_connexion(server, port, database, username, password, timeout):
return db2.connect('DATABASE={0};'.format(database) +
                  'HOSTNAME={0};'.format(server) +
                  'PORT={0};'.format(str(port)) +
                  'PROTOCOL=TCPIP;' +
                  'UID={0};'.format(username) +
                  'PWD={0};'.format(password) +
                  'ConnectTimeout={0};'.format(str(timeout))
                  , '', '')

--sample connexion object

connexion = make_connexion('server', 'port', 'database', 'username', 'password', 'timeout')

在使用easy_install ibm_db卸载并重新安装ibm_db软件包之后，我注意到一条警告消息，上面写着警告：在目录“ibm_db_dlls”下找不到与“”匹配的文件*
