Imported module cannot be found when Python script is run via a bat file

I know there has been similar problems, but unfortunately most of them are related to errors with pyperclip itself instead of the batch file, which i suspect is where the problem stems from.
Below is an MRE of my Python script:
#! python3 -> Do I have to use my version(3.8)?
# pw.py - An insecure password locker program.
import sys, pyperclip
#do something with the module
And my batch file pw.bat:
#py.exe C:\Users\KEVIN\PycharmProjects\atbs_exercise\pw.py %*
#pause
I am running python 3.8 on windows 10. I imported the pyperclip module in my python script pw.py and ran the file via pw.bat, and this in turn gives me this error:
Traceback (most recent call last):
File "C:\Users\KEVIN\PycharmProjects\atbs_exercise\pw.py", line 7, in <module>
import sys, pyperclip
ModuleNotFoundError: No module named 'pyperclip'
Press any key to continue . . .
Which shouldn't happen as I have installed pyperclip on the project using pip, and the script itself runs just fine in pycharm. What am I missing?
EDIT: I forgot to mention that I am using pycharm. So the thing is that pycharm had also installed python.exe in the project folder. And as the module pyperclip is only installed to that folder, the python.exe used in the bat must point to the one in the project folder.

i don't know why are you using py.exe. when running commands from a batch file or cmd .you should use python.exe.obviously you would need to add python to add for doing so.instead of adding py.exe to path,add python in system variable Path which is somewhere present in C:\Users\[username]\AppData\Local\Programs\Python\(your path might be diffrernt).you can add python in Path by following this post
after adding python to path just use the following batch-file:
#echo off
python path-to-your-py-file\filename.py

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

ImportError when execute script from command line

When executing script from command line, I got the following error
ImportError: No module named SubPackage3.MyClass
My package is structured as
TopLevelPackage
..SubPackage1
..SubPackage2
..SubPackage3
..__init_.py
..README.md
python (/usr/bin/python)
From other posts it seems that the problem is that the system does not recognize the path to SubPackage3. I have a separate __init_.py in each of the SubPackage, and print(sys.path) gave me
/home/shaunz/workspace/TopLevelPackage/SubPackage1
/home/shaunz/workspace/TopLevelPackage
/usr/lib/python2.7
....
Notice that only Package 1 is in the list of paths recognized. Any idea why this may be the case? And how do I change it?
I'm trying to run a module in SubPackage2. I'm using Eclipse.
Thanks

importError using a virtualenv from cmd on Windows

trying to run a flask dev server on localhost:5000 using a virtualenv on Windows 7
In my command line in the project directory, i activated the virtualenv with the command "env\scripts\activate". It seemed to work, as my next line was preceded with an (env) tag. When I attempted to run the app file (bank_app), however, I got an import error.
Here's the console log
C:\Users\TJ\Documents\Python Projects\TestingPython> env\scripts\activate
(env) C:\Users\TJ\Documents\Python Projects\TestingPython> bank_app
Traceback (most recent call last):
File "C:\Users\TJ\Documents\Python Projects\TestingPython\bank_app.py", line 1, in <module>
from flask import Flask
ImportError: No module named flask
and here's a gist of the bank_app file (just in case it's relevant)
I'm used to running the code directly from PyCharm, which handles the virtualenv for me. it works fine running directly from PyCharm

This is probably related to how Windows maps extensions to executables.
You started the script with bank_app, which is really not the name of your script (your script has a .py extension I assume?). Windows must be doing a search in your directory, and then starting the script with the interpreter that is registered for the .py extension of the script, which is the globally installed interpreter, not the interpreter that is currently in the PATH.
I'm pretty sure if you run the command as python bank_app.py everything will work just fine.

Importing modules with python

I'm working with python 2.7 (32-bit) on Windows Vista. I downloaded some libraries including numpy, scipy, and pygame. When I try to import these modules the output says
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
import numpy
ImportError: No module named numpy
I can find these modules in my python folders but for some reason it doesn't want to recognize it or some thing. (I made sure the file were compatible before downloading.)

Each package should contain a setup.py file. Run this with the command python setup.py install
For more information:
http://www.scipy.org/Installing_SciPy/Windows
http://pygame.org/install.html

"Everytime I run the command "python setup.py install" in the python shell it says SyntaxError: invalid syntax "
Please create a folder where you unzip the "numpy.zip" file, say the folder name is "c:\numpy"
Open a MS-DOS terminal (as described here : http://en.wikipedia.org/wiki/Command-line_interface), and type :
cd c:\numpy
python setup.py config
python setup.py install
This will set up the needed files in the correct folders for your python.
Enjoy !

To properly install this module:
In the Windows search bar (START MENU) type Command Prompt
Right-click on the Command Prompt icon (DO NOT go to cmd)
Click Run as Administrator
in the COMMAND PROMPT (DO NOT open cmd) type:
pip install numpy
This will install that module.
NOTE: If you are NOT in admin mode, you will get a message saying a fatal error has been raised.
