I wrote a script a few months ago using python. In this script I use weave. This script used to work, but I retried running my program today after a few month and it doesn't work anymore. I get this error:

The error states: cannot find -lpython27
this is how the folder looks like (which the program is using)
Some extra information: I have a 64 bit pc, running windows 7, python is 32 bit.
Recently my Path variable was cleared, though I've added the python path to it, maybe I need to add something here too ?
It is finding python27.lib (in the python folder) but is skipping it as incompatible most likely as it was built with Visual C++ and you are using gcc - You probably had a gcc build of python on your path - if so you need to add it back or set the linker path to include . i.e. the current directory.

I am using bash terminal in vscode. When I try to run my code:

from pyaudio import speech_recognition as sr
r = sr.Recognizer()

with mic as source:

On Windows 10 Build 14393 with Python 3.7.0, Cython 0.29.6 and MinGW32 located at C:\MinGW with the path C:\MinGW\bin on the system PATH environment variable, I am unable to get Cython code to compile using MingW. When I attempt to, I receive the following:
running build_ext

error: Unable to find vcvarsall.bat

tree = Parsing.p_module(s, pxd, full_module_name)
I have tried various fixes, such as those mentioned here, to no avail. After making the config file as instructed in that solution, (but before changing cgwinccompiler.py), I attempted to compile again but then received this error:

return ['vcruntime140']
to the cygwinccompiler.py file and copied vcruntime140.dll to the C:\Program Files\Python\Python37\libs folder, but then I receive this error upon attempting to compile:

To be clear, my setup.py file looks like this:

from Cython.Build import cythonize
import numpy
setup(
ext_modules = cythonize("abc_image_stats.pyx"),
include_dirs=[numpy.get_include()] # https://stackoverflow.com/a/14657667
)
and I am attempting to compile using python setup.py build_ext --inplace via the command line.
All I want to do is compile the Cython code on a Windows 10 machine using MingW. I've tried everything I can think of and don't know what's wrong. Any ideas on how to solve this?
try to change
elif msc_ver == '1914':
return ['vcruntime140']
to return ['msvcr100']
this worked for me, don't really know why though

I used a docker file several months ago that (1) uses base ubuntu image, (2) installs miniconda python distribution, (3) installs some python libraries using miniconda, (4) runs following commands to set up cassandra-driver for python.
RUN pip install --upgrade pip
RUN pip install cassandra-driver
This worked perfectly six months ago. But now I'm getting this exception.

distutils.errors.DistutilsError: Setup script exited with error: command 'gcc' failed with exit status 1
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-0XzsPv/cassandra-driver
The command '/bin/sh -c pip install cassandra-driver' returned a non-zero code: 1
What might be going wrong? Is the installation package broken or I'm not doing it right?
The python cassandra-driver now uses Cython extensions by default since version 2.7.0, but there is an escape hatch for those who don't have easy access to the cython distribution or don't need it which might be a good option for you as well. The cython extensions do offer a boon to performance, but it might not be suitable for a lot of cases (especially where you are not doing high throughput).
From the install documentation:
By default, this package uses Cython to optimize core modules and build custom extensions. This is not a hard requirement, but is engaged by default to build extensions offering better performance than the pure Python implementation.
This build phase can be avoided using the build switch, or an environment variable:
python setup.py install --no-cython
-or-
pip install --install-option="--no-cython" <spec-or-path>
Alternatively, an environment variable can be used to switch this option regardless of context:
CASS_DRIVER_NO_CYTHON=1 <your script here>
In order to install cassandra-driver you need to compile some C source files however you don't have gcc inside your container:
unable to execute 'gcc': No such file or directory
Try to install gcc and python-dev packages before installing cassandra-driver:
RUN apt-get update \
&& apt-get install -y --no-install-recommends \
python-dev \
gcc \
&& rm -rf /var/lib/apt/lists/*

weave.test() didn't find any errors but it only ran 146 tests and the documentation http://docs.scipy.org/doc/scipy/reference/tutorial/weave.html says that it should have ran 180.

...quite some time ago I ran into issues with compiling weave code. The problem was probably caused by mixing (Visual Studio) precompiled Python with MinGW-compiled weave code.
Back then, I was using the MinGW64 compiler (MinGW32 worked as well) and developed a three step workaround.
1) In the <pythondir>\libs directory, delete the MSVCR runtime library file, it should be named something like libmsvcr100.a or libmsvcr100d.a (or with 90 or any other version number in it). Along with it delete any file in the folder that has the same creation date (first attempt of using weave).
2) in the (probably not yet created) file <pythondir>\Lib\distutils\distutils.cfg and also <pythondir>\Lib\site-packages\numpy\distutils\distutils.cfg I included the compiler definition
[build]
compiler = mingw32
Maybe you'd need to adjust that to your type of compiler.
3) In <pythondir>\Lib\site-packages\numpy\distutils\mingw32ccompiler.py there comes the real "hack" at around line #329:
in the function implementation of build_msvcr_libaray(debug=False) just hardcode return False as the first line of code.
Now retry your weave code...
