尝试导入pypyodbc模块会出现错误'找不到ODBC库。是否设置了LD_LIBRARY_PATH？' [英] Trying to import pypyodbc module gives error 'ODBC Library is not found. Is LD_LIBRARY_PATH set?'

问题描述

我在Linux Mint 18上运行Python 3.5。我想加载 pypyodbc 模块。但是，无论我尝试什么，我总是得到错误：

I am running Python 3.5 on my Linux Mint 18. I want to load the pypyodbc module. However, no matter what I try, I always get the error:

OdbcNoLibrary: 'ODBC Library is not found. Is LD_LIBRARY_PATH set?'

在在python中导入之前设置LD_LIBRARY_PATH 我得到了建议将路径设置为 os.getcwd（） ，但它也没有用，并给了我同样的错误。

In Set LD_LIBRARY_PATH before importing in python I got the suggestion to set the path to os.getcwd(), but it did not work either and gave me the same error.

我应该安装什么才能使它工作？

What should I install to make it work?

推荐答案

安装 python-pyodb 包解决了它：

sudo apt-get install python-pyodbc

现在导入成功：

In [2]: import pypyodbc

In [3]:
