[驱动程序管理器]无法打开库'/opt/microsoft/msodbcsql17/lib64/libmsodbcsql-17.9.so.1.1‘

Question

当我运行$ python manage.py inspectdb --database=mssql_database时

我有以下错误

django.db.utils.Error: ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib '/opt/microsoft/msodbcsql17/lib64/libmsodbcsql-17.9.so.1.1' : file not found (0) (SQLDriverConnect)")

但是文件libmsodbcsql-17.9.so.1.1在那里。

$ cat /etc/odbcinst.ini

OS：Ubuntu 18.04.6 LTS

我刚开始使用干净的系统，现在正在创建virtualbox的快照。这是安装SQL Anywhere Database Client的结果。见这里。我需要SQL Anywhere Database Client和Sybase一起工作。在完成这个安装之后，我有上面的错误。

$ pip list
Package       Version
------------- -------
Django        1.8
django-pyodbc 1.1.3
pip           21.3.1
pyodbc        4.0.32
setuptools    59.6.0
sqlany-django 1.13
sqlanydb      1.0.11
wheel         0.37.1

Answer 1

虽然对于此特定情况不是一个完整的答案，但对于在同一台计算机上使用sqlanydb (用于SAP SQL Anywhere)和pyodbc (对于Microsoft SQL Server)都有困难的其他人来说，以下信息可能会有所帮助。

问题中引用的SQL设置说明指示我们

source "/opt/sqlanywhere17/bin64/sa_config.sh"

在.bashrc中。该脚本部分包括

LD_LIBRARY_PATH="$SQLANY17/lib32:${LD_LIBRARY_PATH:-}"
LD_LIBRARY_PATH="$SQLANY17/lib64:${LD_LIBRARY_PATH:-}"
export LD_LIBRARY_PATH

它将SQLANY17/目录添加到任何现有的LD_LIBRARY_PATH中。在Xubuntu20.04的普通安装上，没有定义LD_LIBRARY_PATH，因此最终的结果是

$ echo $LD_LIBRARY_PATH 
/opt/sqlanywhere17/lib64:/opt/sqlanywhere17/lib32:

这对sqlanydb很好

# any.py
import sqlanydb
# Initiate connection to the database
DB_PARAMS = {"HOST": "192.168.0.199",
         "USER": "dba",
         "PASSWORD":"sql",
         "DB":""}
conn = sqlanydb.connect(host=DB_PARAMS['HOST'], uid=DB_PARAMS['USER'], pwd=DB_PARAMS['PASSWORD'], dbn=DB_PARAMS['DB'])
# Instantiate cursor
curs = conn.cursor()
# Execute a query
curs.execute("SELECT 'success' as connection_status FROM SYS.DUMMY")
result = curs.fetchall()
print(result)

$ python3 any.py
[('success',)]

但是它会导致pyodbc失败

# pyo.py
import pyodbc

cnxn = pyodbc.connect(
    "Driver=ODBC Driver 17 for SQL Server;"
    "Server=192.168.0.199;"
    "Database=test;"
    "UID=scott;PWD=tiger^5HHH;"
)
crsr = cnxn.cursor()
print(crsr.execute("SELECT 'success' AS connection_status").fetchall())

$ python3 pyo.py 
Traceback (most recent call last):
  File "pyo.py", line 3, in <module>
    cnxn = pyodbc.connect(
pyodbc.Error: ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib '/opt/microsoft/msodbcsql17/lib64/libmsodbcsql-17.9.so.1.1' : file not found (0) (SQLDriverConnect)")

如果我们将第三个LD_LIBRARY_PATH调整到sa_config.sh中

LD_LIBRARY_PATH="$SQLANY17/lib32:${LD_LIBRARY_PATH:-}"
LD_LIBRARY_PATH="$SQLANY17/lib64:${LD_LIBRARY_PATH:-}"
LD_LIBRARY_PATH="/lib/x86_64-linux-gnu/:${LD_LIBRARY_PATH:-}"
export LD_LIBRARY_PATH

并重新启动机器以应用更改，然后any.py (上面)继续工作，但pyo.py (上面，未修改)也能工作：

$ python3 pyo.py 
[('success', )]

Answer 2

看起来您有驱动程序问题，运行下面的命令，它应该可以工作

sudo apt-get install tdsodbc

更新odbcinst.ini的内容

$ sudo nano /etc/odbcinst.ini 
  [FreeTDS]
  Description = TDS Driver for MSSQL
  driver = path/to/libtdsodbc.so
  setup =  path/to/libtdsS.so

编辑

运行此命令后，请共享输出

  import pyodbc
  print(pyodbc.drivers())

此外，请检查目标操作系统是否遵循了所有步骤：
