无法打开 lib '/usr/local/nz/lib/libnzsqlodbc3.so'：找不到文件 (0) (SQLDriverConnect)")

Question

我正在尝试使用 pyodbc 访问 IBM Netezza 数据库。我正在使用 unixODBC2.3.7

odbcinst.ini

[NetezzaSQL]
Driver           = /usr/local/nz/lib/libnzsqlodbc3.so
Setup            = /usr/local/nz/lib/libnzsqlodbc3.so
APILevel         = 1
ConnectFunctions = YYN
Description      = IBM Netezza ODBC driver
DriverODBCVer    = 03.51
DebugLogging     = false
LogPath          = /tmp
UnicodeTranslationOption = utf8
CharacterTranslationOption = all
PreFetch         = 256
Socket           = 16384

我收到此错误： pyodbc.Error: ('01000', "[01000] [unixODBC][Driver Manager]无法打开 lib '/usr/local/nz/lib/libnzsqlodbc3.so' : 找不到文件 (0) ( SQLDriverConnect)")

我尝试调试它，发现缺少共享库链接：libcom_err.so.2 => 未找到
