Error when using winshell module: No module named 'win32'

import winshell
r = list(winshell.recycle_bin())
for index, value in enumerate(r):
print(index, value.original_filename())
This is the simple script I wrote, but when I try running it (or antyhing else that uses winshell) I get this error:
ModuleNotFoundError: No module named 'win32'
And when I try running pip install win32 I get another error:
ERROR: Could not find a version that satisfies the requirement win32 (from versions: none)
ERROR: No matching distribution found for win32
So now I'm even more confused. Why does winshell need a different module? That module doesn't even exist. Is it fine if I use some different module than the non-existent win32? If so which one? What am I supposed to do now?

First, you have to execute the script inside the Scripts directory, the pywin32_postinstall.py. Let’s say your Python directory is C:\python3, just follow the code below.
cd C:\python3
python Scripts/pywin32_postinstall.py -install
After that, the installation will drop the DLL files under the C:\Windows\System32. You need to move those two files ( pythoncom310.dll and pywintypes310.dll) to C:\python3\Lib\site-packages\win32 directory.
After that, you need to edit the python310._pth that you can find inside the Python installation folder. Then make the following changes:
Lib/site-packages
Lib/site-packages/win32
Lib/site-packages/win32/lib
Lib/site-packages/pythonwin
python310.zip
#Uncomment to run site.main() automatically
#import site
Save and try running your code again.
Troubleshoot
If you still get an error saying “ImportError: DLL load failed while importing win32api: The specified module could not be found.”, make sure you have copied the two dll files to Lib\site-packages\win32 directory.

ImportError: No module named pygments.styles when attempting to run Pythontex

When I try to run pythontex via my command line((base) Zachs-MacBook-Pro:mat_300 zachmaurus$ pythontex pythontex.tex) the following occurs:
Traceback (most recent call last):
File "/Library/TeX/texbin/pythontex", line 50, in <module>
import pythontex2 as pythontex
File "/usr/local/texlive/2019/texmf-dist/scripts/pythontex/pythontex2.py", line 61, in <module>
from pygments.styles import get_all_styles
ImportError: No module named pygments.styles
How do I go about solving this issue? I have downloaded pygments with pip install, but for whatever reason when I attempt to run the script the module pygments.style cannot be found.

Solved this issue by adding pythontex_install.py to my PATH using export PATH=$PATH:/usr/zachmaurus/Downloads/pythontex/pythontex_install.py in MacOS Terminal. To ensure that pythontex_install.py has been added to PATH environment run echo $PATH and it should appear as one of the variables. After having added pythontex_install.py to PATH, I now get the following result when I run pythontex pythontex.tex to compile my document:
This is PythonTeX 0.16
--------------------------------------------------
PythonTeX: pythontex - 0 error(s), 0 warning(s)

I solved this problem by explicitly call the interpreter I want, wenn I compile the document.
pdflatex -interaction=nonstopmode document.tex
python3 <path_to_pythontex.py>/pythontex.py document.tex
pdflatex -interaction=nonstopmode document.tex
or for any python interpreter you want:
pdflatex -interaction=nonstopmode document.tex
<path_to_python>/python3 <path_to_pythontex.py>/pythontex.py document.tex
pdflatex -interaction=nonstopmode document.tex
Of course Pygments module schuld be installed by this interpreter. This worked very good for me on macOS.

I got the same problem when I tried to use pythontex on my macbook (on macOS Catalina 10.15).
What I suggest below must be (if used) used with precaution :
I tried so many solutions and what actually worked for me was this :
I made sure that pygments was installed on my machine (I ran 'pip install pygments' on the terminal)
Then I changed the first line of the files pythontex, pythontex2 (because the problem seemed to come from there) and pythontex3
Theses files (if you are using macOS Catalina 10.15 like me) should be in
/usr/local/texlive/2021/texmf-dist/scripts/pythontex
(if you installed TexLive2021) -> you should be able to retrieve this path when you try to compile your tex file anyway...
The first line was replaced by #!/usr/bin/python3 (to ensure that python3 was used instead of python 2.7 which is used by default by macOS) inside the 3 files pythontex, pythontex2 and pythontex3 then :
I ALSO added this line (see the screenshot below) in pythontex3 :
sys.path.append('/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/')
to ensure that python found the module pygments
(because I installed python3.9 on my machine and the folder "pygments" and its subfolder "styles" was present in the folder "site-packages")
pythontex3 file
So now everything is working fine again and I can use pythontex =)

Cannot install custom python module

I am having trouble installing a custom python module I have written.
Here are my steps so far:
Navigate to the module directory C:\Users\myname\repos\mymodulename where the setup.py file is in the anaconda prompt. Type: python setup.py install
The command prompt returns (plus some other things)
Extracting mymodulename-0.1-py3.7.egg to c:\users\myname\appdata\local\continuum\anaconda3\lib\site-packages
mymodulename 0.1 is already the active version in easy-install.pth
Installing myclass-script.py script to C:\Users\myname\AppData\Local\Continuum\anaconda3\Scripts
Installing myclass.exe script to C:\Users\myname\AppData\Local\Continuum\anaconda3\Scripts
Installed c:\users\myname\appdata\local\continuum\anaconda3\lib\site-packages\mymodulename-0.1-py3.7.egg
Processing dependencies for mymodulename==0.1
...
Using c:\users\myname\appdata\local\continuum\anaconda3\lib\site-packages
Finished processing dependencies for mymodulename==0.1
To me that looks like it has installed. Opening up the console and trying to import:
>>> import mymodulename.myclassas ce
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'mymodulename'
>>>
It appears in hasn't. Checking the list of modules in anaconda with help('modules') confirms that it has not been imported.
I thought that perhaps i had installed it to the wrong environment:
(base) C:\Users\myname>conda env list
# conda environments:
#
base * C:\Users\myname\AppData\Local\Continuum\anaconda3
py2 C:\Users\myname\AppData\Local\Continuum\anaconda3\envs\py2
Only a python 2 environment which mymodule wouldn't be compatible with.
Does anyone have any suggestions about what I can try to resolve this? Happy to elaborate on any of the points
Thanks in advance.
EDIT: Some more information that may be relevant.
This package was initially installed in site-packages. I have reinstalled there and the package works. The reason I moved the package is because I am aware it is bad practice to store custom packages there.

Error executing solr-to-es in Anaconda: ModuleNotFoundError: No module named 'solrSource'

I am trying to run solr-to-es (https://github.com/o19s/solr-to-es) in Anaconda environment. I run the setup.py without errors, then when trying to execute "solr-to-es -h", I get "No module named 'solrSource'". I don't get this error when with a Python 2.x environment, however the requirement is Python 3.x.

Hack:
cd solr_to_es
python \__main__.py localhost:8983/solr/select localhost:9200 es_index solr_docs

ImportError: No module named 'xx' in mac and linux

I am right now using the mac and trying to use the module pypng. I have installed the module from pip install pypng. It works well. However when I run my application python test.py (where inside test.py has 'import png'), it gives me a error saying 'ImportError:No module named png'.
However when I go into the python environment from command line, I type 'import png', it works without a error, why is that. I even restart the computer, but still in trouble.
when I installed pypng module, it tells me it is install in /Users/abc1/anaconda/lib/python2.7/site-packages, where inside this directory I can find the png.py and png.pyc.
when i print sys.path, this is the output, looks like it didn't load the png package from /Users/abc1/anaconda/lib/python2.7/site-packages. how do i solve it

Maybe you installed png to your python environment in the command line but not the environment you run your script. Try to use python batch.py in command line, or append /Users/abc1/anaconda/lib/python2.7/site-packages to sys.path.

Do you have a directory in your project that is named png? If so python will try to import it instead of the actual module
