ModuleNotFoundError: No module named 'pyodbc' when importing pyodbc into py script

I've written a short python script which tries to import the pyodbc extension package so I can access my SQL table.

import pyodbc as pyodbc
cnxn = pyodbc.connect('Driver={SQL Server};'
                      'Server=DESKTOP-UO8KJOP;'
                      'Database=ExamplePFData'
                      'Trusted_Connection=yes;')

I have definitely installed the extension by using: pip install pyodbc. And when I go to install it again, cmd says: Requirement already satisfied: pyodbc in ... and I've found the pyd file in my directories.

I have also tried installing pypyodbc, which didn't work.

The error I get is:

Traceback (most recent call last):
File "C:\Users\Jerry\Documents\Python\SQLembed.py", line 5, in <module>
import pyodbc as pyodbc
ModuleNotFoundError: No module named 'pyodbc'

(where line 5 is the 'import pyodbc' line)

I have tried copying the pyodbc.cp37-win_amd64.pyd file into my Python Scripts folder and into the folder where my pip.exe file is.

Currently python is my Python37 folder.
pyodbc.cp37-win_amd64.pyd is in Python > Lib > site-packages.

Can anyone help me fix this error please so that I can import pyodbc?

Do all of the python extensions/modules that I install via pip need to be in the same folder/directory as python.exe?

There is a useful step by step guide here: https://docs.microsoft.com/en-us/sql/connect/python/pyodbc/step-1-configure-development-environment-for-pyodbc-python-development?view=sql-server-2017

For reference, the steps in this guide (windows) are (assuming you already have python installed):

Install the Microsoft ODBC Driver for SQL Server on Windows, from https://docs.microsoft.com/en-us/sql/connect/odbc/windows/system-requirements-installation-and-driver-files?view=sql-server-2017#installing-microsoft-odbc-driver-for-sql-server
Open cmd.exe as an administrator
Navigate to your python scripts folder containing pip
Type: pip install pyodbc

It seems you have already installed the pyodbc module, but are trying to reference it from another environment.

Some Steps:

In the Solution Explorer window right-click Python Environments
select add/remove
choose your desired python interpreter.

Refer: How to switch your project python environment to the one which includes pyodbc

I ran into the same error a few days ago! Thankfully, I found the answer.

You see, the problem is that pyodbc comes in a .whl (wheel) file/package. So, as a result, you have to pip install it.

Pip installing is a very tricky process, so please be careful. The steps are:-

Step1. Go to C:/Python (whatever version you are using)/Scripts. Scroll down. If you see a file named pip.exe, then that means that you are in the right folder. Copy the path.

Step2. In your computer, search for Environment Variables. You should see an option labeled 'Edit the System Environment Variables'. Click on it.

Step3. There, you should see a dialogue box appear. Click 'Environment Variables'. Click on 'Path'. Then, click 'New'. Paste the path that you copied earlier.

Step4. Click 'Ok'.

Step5. Open the Windows File Explorer. Shift + Right Click wherever your pyodbc.whl file is installed. Select 'Open Command Window Here' from the dropdown menu. Type in 'pip install py', then click tab and the full file name should fill in. Then, press Enter, and you're ready to go! Now you shouldn't get the error again!!!

I also faced the same issue. You can try the following method :

a) You can install the ODBC Driver for SQL Server. Visit:
https://docs.microsoft.com/en-us/sql/connect/odbc/windows/system-requirements-installation-and-driver-files?view=sql-server-2017#installing-microsoft-odbc-driver-for-sql-server

b) Uninstall Python and close all your IDLE and install Python again. This worked for me.
