I'm trying to install PyUblas on my Windows machine. I have Visual Studio 2017 Community edition. I've tried installing using
pip install pyublas
but get the following error message:

On the documentation page there is also a two-line description of an alternative installation method using Boost.Build; however, it seems rather outdated or at least I wasn't able to get it to work or even to understand it. I've compiled Boost but not sure what I'm supposed to do then. It seems bjam has since been superceded by b2 but running that didn't help. I also couldn't find anything useful by searching either Google or on here.
EDIT:
I have tried removing the offending lines from setup.py and installing manually as per TheGreatParker's suggestion. I have also removed references to the flag in question in lines 109 and 119 because they were throwing up errors. Now I get the following error:
src/wrapper/main.cpp(16): fatal error C1083: Cannot open include file:
'boost/python.hpp': No such file or directory
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Community\\VC\\Tools\\MSVC\\14.12.25827\\bin\\HostX86\\x86\\cl.exe' failed with exit status 2error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Community\\VC\\Tools\\MSVC\\14.12.25827\\bin\\HostX86\\x86\\cl.exe' failed with exit status 2
I've tried copying the boost folder containing python.hpp into the installation folder but this didn't seem to help.
EDIT2:
I have rebuilt boost and made sure that the installation configuration file created by configure.py (which is siteconf.py) correctly links to the boost directories. Now I get the following error:
LINK : fatal error LNK1181: cannot open input file 'boost_python36-vc141-mt-x32-1_67.lib'
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Community\\VC\\Tools\\MSVC\\14.12.25827\\bin\\HostX86\\x86\\link.exe' failed with exit status 1181
I gather that the file it wants is in the boost library directory which for me is boost_1_67_0\stage\lib\. The file in question is actually called libboost_python36-vc141-mt-x32-1_67.lib so I thought the problem was that it was missing the 'lib' in the beginning. However, when I changed siteconf.py:
BOOST_PYTHON_LIBNAME = ['libboost_python36-vc141-mt-x32-1_67']
I got the following error:
LINK : fatal error LNK1104: cannot open file 'boost_pythonPY_MAJOR_VERSIONPY_MINOR_VERSION-vc141-mt-x32-1_67.lib'
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Community\\VC\\Tools\\MSVC\\14.12.25827\\bin\\HostX86\\x86\\link.exe' failed with exit status 1104
Seems that either way it can't access this file. I have also tried making a copy of the file libboost_python36-vc141-mt-x32-1_67 and renaming it what the installation is looking for. In this case I get a whole bunch of errors of the sort:
main.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) struct boost::python::converter::registration const * __cdecl boost::python::converter::registry::query(struct boost::python::type_info)" (__imp_?query#registry#converter#python#boost##YAPBUregistration#234#Utype_info#34##Z)
until the installation exits with error

You could try to install this package manually:
Clone source code;
Open setup.py and remove python logic which adds this flag. (in my version they are lines 16, and 17:
StringListOption("CXXFLAGS", ["-Wno-sign-compare"],
help="Any extra C++ compiler options to include"),
Use python setup.py install to install the package with changed setup.py
Hope this will help you.
conda install pyublas
You need to install anaconda/miniconda from

It seems like all fails is due to a missing file msvc_recommended_pragmas.h. This leaves me with no clue of what I may have missed. All runtime dependencies involved (python3.9, pip, MSYS2, C++ Build Tools from Visual Studio) have been upgraded to the latest version FYI.
gvsbuild provides a method to compile GTK in Windows. The latest instructions can be found in the README at https://github.com/wingtk/gvsbuild. Once you install the dependencies, it will work something like this:
mkdir C:\gtk-build\github
cd C:\gtk-build\github
git clone C:\github.com\wingtk\gvsbuild
python -m venv .venv
.\.venv\Scripts\activate.ps1
pip install .
gvsbuild build --enable-gi --py-wheel gobject-introspection gtk3 pycairo pygobject
Once that builds, you can switch to your project you are trying to use PyGObject for and activate the virtualenv. Then install the wheels you created above:
Get-ChildItem C:\gtk-build\build\x64\release\*\dist\*.whl | ForEach-Object -process { poetry run pip install $_ }

I had a similar issue. Finally, I solved it buy:
Deleting build directory in Detectron2 (rm -rf build/ **/*.so)
cd to the Detectron2 and pip install -e.
It builds the wheel again.

Almost 100% of the times when I get Visual Studio errors when using pip I fetch the wheel file of the module I wish to install, then use pip on that local file.
https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyopencl
The link I provided will take you to the pyopencl area, this website is a wheel repository for many modules, I used it to install PyCairo as well when it was giving me VS errors. Select the pyopencl module that matches your Python version (For Python 3.7 it will be -cp37-), then select what OpenCL version you wish to use (For CL 2.1 it is +cl21-), then lastly select "amd64" or "win32" if you're on a 64-bit or 32-bit OS. Once you have the file downloaded point pip in the direction of the file, example command: pip install C:\Users\Mihir\Downloads\pyopencl-2018.2.2+cl21-cp37-cp37m-win_amd64.whl that will then install module (Treat a wheel file like a compressed ZIP or TAR). Make sure you have pyopencl prerequisites, which are numpy and cffi (It says Mako too, but I think it works without it).
I faced same problem and i couldn't install pyopencl. I was using python 3.7 in 64 bit windows. So i used pyopencl‑2018.2.5+cl21‑cp37‑cp37m‑win_amd64.whl version. But unfortunately it didn't work.
So i tried with pyopencl‑2018.2.5+cl21‑cp37‑cp37m‑win32.whl version and then it installed successfully.
Put pyopencl-2018.2.2+cl21-cp37-cp37m-win_amd64.whl in System32,
then tap in the power shell
pip install pyopencl-2020.3.1+cl21-cp39-cp39-win_amd64.whl

Any help would be most welcome
You can get the most recent version of libmemcached from its Launchpad download page.
With this, make sure that all headers are available from the include search path, which in your case would be C:\Python34\include (as hinted by the output); you could also place them in the search path of your compiler (which for MinGW's gcc would be something like mingw64\lib\gcc\x86_64-w64-mingw32\6.3.0\include).
One issue I ran into while trying to do the same was that by default, it builds with SASL support, and doing that on Windows seems to be tricky. You can build libmemcached without SASL support by changing libmemcached\configure.h:45 to #define LIBMEMCACHED_WITH_SASL_SUPPORT 0 (as of version 1.0.18).
