UnicodeDecodeError与pip安装pyodbc

Question

Trying to install pyodbc: pip install pyodbc it got the following error. I install a different item peewee specifically and it install without giving me error. I further tried with pip install pymssql and it also came with a similar error. I am familiar with pyodbc and would like to use it in my flask app.

Anyone with an idea how i can overcome this error.

i followed 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" but could not solve the problem.

I am using ubuntu 14.05.

Answer 1

Most likely the problem is ancient pip you are using - 1.5.6. Upgrade it to the latest with pip install -U pip and check again.

Also, make sure that python-devel is installed.

Answer 2

Thanks for the Help. A friend on one slack page help me through it.

1. export LC_ALL=C this would make pip use the local configuration within the operating system.
2. and pip install --upgrade setuptools
3. pip install pyodbc again and have the following error But no longer the ascii issue

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 We then figured out the second problem to be with gcc compiler since pyodbc was written in C.

And this finally this solved it

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

thank you all for the answers.
