Installing pyodbc failed on Linux

I just run this command:
sudo pip install pyodbc
then I get below message and error:
steven81#PythonWEBVM:~$ sudo pip install pyodbc

I saw there is an error:

then I search in on google, it asked to run this:
sudo apt-get install python-dev
so, I run this but get below message:
steven81#PythonWEBVM:~$ sudo apt-get install python-dev

python-dev is already the newest version (2.7.12-1~16.04).
0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded.
so what's the problem and how to install pyodbc correctlly?

For anyone looking for the pyodbc install to connect to SQLServer from Linux(ubuntu).
sudo apt-get install unixodbc-dev
sudo apt-get install python3-dev
python3 -m pip install pyodbc

And I've heard that installing python3-dev would resolve the problem.
I tried with no succes.
I'm using python 3.4 under CentOS 7.
Can I get some help please ? Thanks in advance.

I just went through this using python3.4 and pip3.4 on Centos7 64-bit. (NB you need both python3.4 and pip3.4)
I eventually got it working via pip3.4, but before this would work, I had to take a few extra steps. The steps I took were:
Install the python3.4 development headers:
sudo yum install python34u-devel.x86_64
Install hunspell and hunspell-devel (needed for hunspell.h and hunspell lib):
sudo yum install hunspell hunspell-devel
In /usr/lib64/, add an extra symlink for the hunspell library:
sudo ln -s libhunspell-1.3.so libhunspell.so
Finally, run the command:
sudo pip3.4 install hunspell
... and this gave me the following output:
... (compiler output deleted) ...
Successfully built hunspell
Installing collected packages: hunspell
Successfully installed hunspell-0.4.1

Try This:
sudo apt install python-dev libhunspell-dev
pip install hunspell

Solution by OP.
I figured it out, I'll share this method here, it may help :)
first you need to install python-devel and
yum install python-devel
yum install hunspell-devel
then corrected your symlink
cd /usr/lib64
sudo ln -s libhunspell-1.3.so.0.0.0 libhunspell.so
ls -l | grep hunspell
Good Luck :)

I am working on MAC OS and this solved the error for me.

What would cause this? Something about setting include directories?

The issue you're seeing with installing fastcluster is related to this previous question - the compiler is not looking in the correct directory to find the numpy headers. You can use more or less the same solution as given in the accepted answer:
Download and untar the source for fastcluster
$ pip install fastcluster --download='.'
$ tar -xzf fastcluster-1.1.17.tar.gz
$ cd fastcluster-1.1.17/
Edit the setup.py file to add the output of numpy.get_include() to the include_dirs= argument for the Extension:
import numpy
...
ext_modules=[Extension('_fastcluster',
['src/fastcluster_python.cpp'],
extra_compile_args=['/EHsc'] if os.name=='nt' else [],
include_dirs=[numpy.get_include()]
)]
Install fastcluster:
$ python setup.py install
Let the fastcluster maintainer know that his package is broken :-)

I think this may solve your problem:
