Turbodbc installation on Windows 10

I tried installing turbodbc and it gives me the following error and not sure what's wrong here.
My python version is 3.7
My command line output from Windows 10 Pro.

Disclaimer : Turbodc installation has problems with python version 3.8+. You will be able to install Turbodc on python 3.8+, but you'll face another error while using it (https://github.com/blue-yonder/turbodbc/issues/258). So if you want to use Turbodbc, better to stick to python version 3.7 and below. Now lets get Turbodbc installed on your machine
This is going to be a long one. Stay with me -
As the error states, firstly you need 'Microsoft Visual C++ Build Tools'. You'll get it on this page: https://visualstudio.microsoft.com/downloads/. Scroll down to 'Build Tools for Visual Studio'. Download it.
Run the installer. Select 'C++ build tools' to install. Make sure to choose 'Windows 10 (or whatever version you prefer) SDK' as well to prevent this error later - https://github.com/openssl/openssl/issues/586
After installing build tools if you try to install Turbodbc (pip install turbodbc), you'll see another error - python fatal error C1083: Cannot open include file: 'boost/locale.hpp'. Which is to say the battle is half won. To resolve this error follow the steps listed here - https://github.com/blue-yonder/turbodbc/issues/236. For your ease, I'll copy them below -
Download boost from https://www.boost.org/ (click on the "Current Release" version link, in my case "Version 1.72.0", then download the Windows zip file).
Unzip the zipfile somewhere on your PC.
In a command prompt, navigate to the boost top-level directory.
Run .\bootstrap.bat (this generates the b2 executable)
Run .\b2 (this generates the stage directory and contents, takes a few minutes to run)
Set the BOOST_ROOT env variable with something like
set BOOST_ROOT=C:\your\path\to\boost\boost_1_72_0\boost_1_72_0
Run pip install turbodbc
That's all. Turbodbc should now be installed in your machine.

Try follow

I've tried to install both, pymqi and py3mqi and I'm getting the same error. I'm using Python 3.6, 32-bit.
Also, I have MQ Client installed as well as Visual Studio 15. There is the following path on my disk: C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC, but PlatformSDK\\lib is missing.

As JoshMC states pymqi now supports Python 3, and should be what you are using.
pymqi binds to the MQI C Layer, and requires access to MQ C Header files as well as a C compiler / linker, when it installs.
The error you are getting is a common Visual Studio error, when the Windows Platform SDK has not been installed. Essentially installing Visual Studio does not mean that you have installed the C / C++ compiler, and you need to do that also.

Did you consider trying to install Visual Studio 2019 with the python and c package?
That is needed for some packages.
An other possible option is, that py3mqi isn't available for Python 3.6.*

Error while installing PyGraphviz (Mac OS X, Anaconda)

Your Graphviz installation could not be found.
1) You don't have Graphviz installed:
Install Graphviz (http://graphviz.org)
2) Your Graphviz package might incomplete.
Install the binary development subpackage (e.g. libgraphviz-dev or similar.)
3) You are using Windows
There are no PyGraphviz binary packages for Windows but you might be
able to build it from this source. See
http://networkx.lanl.gov/pygraphviz/reference/faq.html
If you think your installation is correct you will need to manually
change the include_dirs and library_dirs variables in setup.py to
point to the correct locations of your graphviz installation.
The current setting of library_dirs and include_dirs is:
library_dirs=None
include_dirs=None

brew install graphviz
then:
pip install --install-option="--include-path=/usr/local/include/" --install-option="--library-path=/usr/local/lib/" pygraphviz
Both path in bold should NOT contain "graphviz".
https://github.com/pygraphviz/pygraphviz/issues/100#issuecomment-237560404
Worked for me on OSX 10.14.1

Assuming that you've already installed graphviz software:
As described in this blog post use the following parameters whilst trying to run pip install pygraphviz
--install-option="--include-path=/usr/local/include/graphviz/" \
--install-option="--library-path=/usr/local/lib/graphviz"
So the final command would look like pip install pygraphviz --install-option="--include-path=/usr/local/include/graphviz/" --install-option="--library-path=/usr/local/lib/graphviz".
What this does is this explicitly specified where the libraries of the original program (graphviz) exist for the python extension to use. Unfortunately, this doesn't seem to get automatically recognized.
Worked on MacOS Sierra with Python 3.6

try the following (make sure to have anaconda-client installed and updated):
conda install --channel https://conda.anaconda.org/garylschultz pygraphviz

Graphviz can be installed via homebrew: brew install graphviz.
Then do:
cd /usr/local/Cellar/graphviz/VERSION/include/graphviz
mkdir graphviz
cp cgraph.h graphviz/
And finally:
pip install graphviz
Tested on Sierra and woks fine.

Did i miss anything?
Any help in that would be great!

What you need is to have Microsoft Visual C++ 10.0 compiler (and as far as I remember version 10.0 doesn't necessarily mean Visual Studio 2010) installed on your system and vcvarsall.bat accessible from PATH environment variable.
However, it is usual for Windows to have enormous amount of blocking issues connected with compiling python extensions via pip (or it's just me?), so my usual workaround of the error you get is to google some Windows binary installers (mysql-python for 2.7 for instance) or .whl files. Both have python extensions compiled for a particular Python and architecture thus eliminating the need in having C or C++ compiler installed.
