无法打开lib'用于SQL Server的ODBC驱动程序13'？Sym链接问题？

Question

当我尝试使用pyodbc(在mac上)连接到sql server数据库时:

import pyodbc

server = '####'
database = '####'
username = '####@####'
password = '#####'
driver='{ODBC Driver 13 for SQL Server}'

pyodbc.connect('DRIVER='+driver+';SERVER='+server+';PORT=1443;DATABASE='+database+';UID='+username+';PWD='+password)

我收到以下错误:

错误:('01000',"[01000] [unixODBC] [驱动程序管理器]无法打开lib'用于SQL Server的ODBC驱动程序13':找不到文件(0)(SQLDriverConnect)")

当我在实际的驱动程序位置路径时:

driver='/usr/local/lib/libmsodbcsql.13.dylib'

它开始工作了!

我odbcinst.ini看起来像这样:

[ODBC Driver 13 for SQL Server]
Description=Microsoft ODBC Driver 13 for SQL Server
Driver=/usr/local/lib/libmsodbcsql.13.dylib
UsageCount=1

如何让我参考driver='{ODBC Driver 13 for SQL Server}'再次开始工作？

我最初使用本指南来安装驱动程序.如果有帮助的话,我在Mac Sierra上使用anaconda？

Answer 1

运行:

odbcinst -j

它产生了:

unixODBC 2.3.4
DRIVERS............: /etc/odbcinst.ini
SYSTEM DATA SOURCES: /etc/odbc.ini
FILE DATA SOURCES..: /etc/ODBCDataSources
USER DATA SOURCES..: /Users/emehex/.odbc.ini
SQLULEN Size.......: 8
SQLLEN Size........: 8
SQLSETPOSIROW Size.: 8

而不是将文件复制到/etc/目录(不知道为什么unixODBC认为他们在那里)我创建了一个指向每个文件的符号链接:

sudo ln -s /usr/local/etc/odbcinst.ini /etc/odbcinst.ini
sudo ln -s /usr/local/etc/odbc.ini /etc/odbc.ini

这解决了这个问题.

Answer 2

在我的情况下,我必须将pyodbc数据库驱动程序字符串更改为
driver='{ODBC Driver 17 for SQL Server}'

实际上,在我的python代码中,pyodbc期待ODBC驱动程序13
但是,由于ODBC驱动程序版本已更新(因为ubuntu更新)到当前版本的ODBC驱动程序17,因此出现了问题.

Answer 3

就我而言，我有一个Mac OS，以下命令解决了该问题：

brew tap microsoft/mssql-release https://github.com/Microsoft/homebrew-mssql-release
brew update
brew install msodbcsql mssql-tools

Answer 4

就我而言，我通过以下三个步骤解决了该问题：

# Step1: install unixodbc 
brew install unixodbc

# Step2: install Microsoft ODBC Driver for SQL Server on MacOS

brew tap microsoft/mssql-release https://github.com/Microsoft/homebrew-mssql-release
brew update
brew install msodbcsql mssql-tools

# Step3?verify odbcinst configuration path is correct

odbcinst -j

sudo ln -s /usr/local/etc/odbcinst.ini /etc/odbcinst.ini
sudo ln -s /usr/local/etc/odbc.ini /etc/odbc.ini

Answer 5

curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add -
curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list > 
/etc/apt/sources.list.d/mssql-release.list 
apt-get update
ACCEPT_EULA=Y apt-get install msodbcsql17
apt-get -y install unixodbc-dev
sudo apt-get install python3-pip -y
pip3 install --upgrade pyodbc

使用上述步骤正确安装 odbc 驱动程序，一切都会就位。

Answer 6

我在 Python 之上构建了一个自定义图像，这是使其工作的配置：

FROM python:3.8 as pyodbc

COPY . /app
WORKDIR /app
