【问题描述】：

我正在尝试使用 unixODBC 驱动程序将 I 系列驱动程序与 pyodbc 一起使用，但我在连接时遇到问题
Pyodc v- 4.0.31
ibmiaccess 1..1.0.15-1.0

('01000', "[01000] [unixODBC][Driver Manager]无法打开 lib 'IBM i Access ODBC Driver 64-bit': 找不到文件 (0) (SQLDriverConnect)") 无

avail = pyodbc.drivers()
print (avail)
drivers = [item for item in pyodbc.drivers()]
driver = drivers[-1]
sys = 'xxxxxxxxx'
uname = 'dbuser'
pas ='xxxxxx'
try:
    connection = pyodbc.connect(
    DRIVER= {driver} ,   
    system= {sys},
    uid= {uname},
    pwd={pas},
    autocommit=True)
    
    cursor = connection.cursor()
    cursor.execute(query)
    x = cursor.fetchall()
    
except Exception as e:
        print(e)
        x = None

finally:
    exit

我能够连接到 isql -v

#isql -v dbuser

【解决方案1】：

不熟悉您的设置，但如果我在连接到驱动程序时收到“未找到文件”，则未找到的文件通常是 .so 文件。在最简单的情况下，驱动程序只是丢失且未安装。我遇到的更模糊的情况是 32Bit / 64Bit 不匹配，或者缺少驱动程序的依赖项（如系统上未安装的 .so 文件中）。使用ldd 可以向您展示您的驱动程序所依赖的所有动态库。
