C4365: 'return': conversion from 'std::size_t' to 'Py_ssize_t', signed/unsigned mismatch error

I'm getting a strange error when attempting to install pyodbc on my local machine in command prompt. Some sort of conversion error that might relate to Visual Studio? Any help would be appreciated. I'm running Python 3.8.2.

The message you cite in your question title is just a warning.
warning C4365: 'return': conversion from 'std::size_t' to 'Py_ssize_t', signed/unsigned mismatch
Such warnings are not unusual when building pyodbc from source on Windows.
The actual error is
fatal error C1007: unrecognized flag '-FH4-' in 'p2'
error: command 'C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\cl.exe' failed with exit status 1
and that's because your version of Visual Studio is too old to build pyodbc for Python 3.8. According to …
Building pyodbc from source
… Visual Studio 2019 (version 16) is required, but you appear to have Visual Studio 2015 (version 14).
The strange thing is that pip is trying to build from source when pyodbc 4.0.30 already has a Windows wheel for 32-bit Python 3.8
pyodbc-4.0.30-cp38-cp38-win32.whl
You could try downloading that and then running
pip install pyodbc-4.0.30-cp38-cp38-win32.whl

How to get Poppler running on Windows

I want to install the pdftotext library for python3. For this, I need Poppler. Now, there is a question regarding this (How to install Poppler on Windows?) but the answers do not work for me. Specifically, when I write
conda install -c conda-forge poppler
it tells me that it is looking for conflicts. After quite a long time, it finished successfully but when I then try to run pip3 install pdftotext it tells me

I have also tried the apprachwith copying to program files but that gave me the same result. Any suggestions on what I might do to fix this?

Basically it means that Python needs cl.exe and it expect it at:

No problem, I go to the Environment Variable and i add that path both for my user and for the system:
Then I check if cl.exe is successfully in the path by typing cl in the terminal and it works:
But when I run again pip install gmpy I have the same error.
EDIT: I also tried with pip install gmpy2 and I receive the same error.
Where am I wrong?

Well the actual problem is that you are missing some header file gmp.h:
C:\Users\franc\AppData\Local\Temp\pip-install-du1j9u7s\gmpy\src\gmpy.h(30): fatal error C1083: Cannot open include file: 'gmp.h': No such file or directory
I suggest you try gmpy2, which is a newer version. It has wheels for Windows on PyPI but they are for older versions of Python unfortunately. Pre-built wheels for more recent Python versions are available here. The files are named after the Python version (e.g. cp37 for CPython 3.7) and architecture (e.g. amd64 for 64-bit)
A wheel can be installed like so:
pip install gmpy2‑2.0.8‑cp37‑cp37m‑win_amd64.whl

These are notes for installation on Microsoft Windows:
pip will fetch and install PyAudio wheels (prepackaged binaries). Currently, there are wheels compatible with the official distributions of Python 2.7, 3.4, 3.5, and 3.6. For those versions, both 32-bit and 64-bit wheels are available.
You are using Python 3.7, which is not compatible with PyAudio. However...
EDIT:
As user #Dalen states, there are prebuilt binaries (.exe files) for pyAudio. I installed from their archive stated in documentation but importing pyAudio had an output:
There are unofficial binaries for Windows on this site: https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyaudio .
Download the proper one and install it.

Download the binary installer for Windows and just install the PyAudio package with no nonsense.
PyAudio is built on top of portaudio library and you require portaudio to be there. The binary installer comes with precompiled version of portaudio as a dynamically linked library and there is no need for hunting and compiling the source.
PyAudio is a great library, enjoy working with it.

pip install pipwin
pipwin install pyaudio
Try these commands in prompt. It does not require any manual downloads or searches etc.
pipwin is a complementary tool for pip on Windows. It is capable of installing unofficial python package binaries for Windows provided by Christoph Gohlke

the key info in the error message is "Cannot open include file: 'portaudio.h': No such file or directory"
so you should google it, and you will find it have an answer in stackoverflow:

You are trying to compile pyaudio from source and on a Windows platform that often is more difficult than one would like.
The specific problem you have is that the compiler is trying to find the include file portaudio.h which you don't have because it isn't a standard Windows include file and it is apparently also not in the download package.
It's clear that the reason pip is attempting the compile, rather than doing a binary install, is that the most recent binary installs are for Python 3.6, and you have Python 3.7.
I suggest that you install Python 3.6 alongside your existing Python 3.7 so that you can get going with this module. There may be Python 3.7 bindings available in due course, and then again there may not. The PyPI page for this project hasn't been updated in over 2 years.
