Question

尝试安装pyodbc：pip install pyodbc它出现以下错误。我专门安装了一个不同的项目peewee，它安装时没有给我错误。我进一步尝试了pip install pymssql，它也出现了类似的错误。我熟悉pyodbc并希望在我的烧瓶应用程序中使用它。

任何人都知道如何克服这个错误。

我关注UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 13: ordinal not in range(128)，How to fix: "UnicodeDecodeError: 'ascii' codec can't decode byte"但无法解决问题。

我使用的是ubuntu 14.05。

Answer 1

问题很可能是你正在使用的古老点 - 1.5.6。使用pip install -U pip将其升级到最新版本并再次检查。

另外，请确保安装了python-devel。

Answer 2

感谢您的帮助。一个懒散页面上的朋友帮助我完成了它。

export LC_ALL=C这会使pip使用操作系统中的本地配置。
和pip install --upgrade setuptools
pip install pyodbc并出现以下错误但不再是ascii问题

fatal error: sql.h: No such file or directory #include <sql.h> ^compilation terminated.error: command 'x86_64-linux-gnu-gcc' failed with exit status 1 然后我们想出了gcc编译器的第二个问题，因为pyodbc是用C语言编写的。

这最终解决了它

4.run sudo apt-get install unixodbc-dev && sudo apt-get install pyodbc

谢谢大家的答案。

使用pip install pyodbc
