How to fix 'ImportError: No module named openpyxl'? - python

I am using Python 2.7 and am trying to run a program with openpyxl to work with xlsx files.
In the first line of code:
from openpyxl import Workbook
I get the following error when I run the program from the CMD:
ImportError: No module named openpyxl
I used pip to install version 2.6.0, and if I try to install it again through pip it just says I have the latest version.
Unlike any other question like this that I found here, I am using an IDE called PyCharm which has an option of running the program I am currently editing inside PyCharm, and PyCharm actually recognizes openpyxl and runs great, so why won't it work in the CMD?

This answer is for those who land in this page without having openpyxl installed.
run pip install openpyxl command in your terminal

If you have multiple versions of python installed it might be related to the version of python that's added to your system path.
What I would suggest you do is check your system path and verify that indeed the python/pip you are using from the command line is 2.7. The same thing applies for PyCharm.

Installed selenium with pip, folder is in site-packages, using correct interpreter, but still cannot import (Win10, Python 3.10.9)

I'm trying to use selenium, but can't get python to recognize it.
I installed it first using "pip install selenium" and "pip install webdriver-manager". It is in the folder "C:\Users\{username}\AppData\Local\Programs\Python\Python310\Lib\site-packages\selenium", but I get the error "ModuleNotFoundError: No module named 'selenium'" when I try to import it.(https://i.stack.imgur.com/dVplU.png)
(https://i.stack.imgur.com/wiREJ.png)
Here it is shown as installed with the command "pip list"
(https://i.stack.imgur.com/QhOu7.png)
I also tried uninstalling it and reinstalling with flags that I saw some people say worked, but it didn't make a difference.
(https://i.stack.imgur.com/VTTMU.png)
I only have one python interpreter version installed, 3.10 (so only one python folder, "Python310"). I have pandas in the same site-packages folder which I can import and use no problem.
If anyone knows what the issue might be, please let me know. I can't figure it out for the life of me.
Okay, I solved the issue by completely uninstalling the interpreter which I got from the Microsoft Store and reinstalling it from the official Python website. Now "from selenium import webdriver" works.
Somehow selenium installed in the global scope is not getting recognized within the Virtual Environment of VS Code / PyCharm.
Solution
You need to install Selenium within the Virtual Environment.
Within the Terminal execute the command:
pip install -U selenium

No module named 'odf' due to wrong Python version

I have many different versions of Python, but a version that I use and that terminal show me if use command Python – version is 3.10.0.
When I use command pip list I got a big list of library, including the one I recently installed odfpy.
I open VsCode, choose Python version 3.10.0 and try to import odf but...
ModuleNotFoundError: No module named 'odf'
For sure I need to set something on VsCode or change some configuration in Linux but I cannot find a normal explanation of how to solve this issue.
If I change the Python version in VsCode with 3.8.10, odfpy (and also Django just installed) is recognized. So I suppose that, even if the Python version selected on the terminal is 3.10.0, when I pip install something, is installed on version 3.8.10. How do you manage this?
Please check which pip you are using through the command of pip --version.
After you switch the python interpreter in the VSCode, please create a new terminal, and make sure it has activated the environment you have selected.
I also use VS code and use Python 3.10 and i had try to download the odfpy which has gone alright, i use the command python -m pip install odfpy
try and see if it work for you though.
If it does not work, maybe try and create a virtual environment if you haven't created it yet.
In my case i was getting same error while using import-export django module. Installing odf library didn't worked got same error. I resolve this issue by simply pip install tablib==0.14.0.

pycharm cannot see the module "openpyxl" even though i installed

I am trying to write a python-script to work with dataframes imported from excel table and another one from another source. In order to read excel file into a pandas dataframe i selected "openpyxl" as a preferred engine, however PyCharm claims there is no such module - even though I have earlier installed it.
I am working on conda and i tried to install it both using pycharm terminal and my macbook terminal: when i retype "conda install openpyxl" it returns me
"# All requested packages already installed."
So please help me because it confuses me that PyCharm keeps screaming
"ImportError: Missing optional dependency 'openpyxl'. Use pip or conda to install openpyxl."
while terminal says i already have that module installed
This may happen because your pycharm is using a different interpreter than your command line.
To solve it:
In Pycharm, go to File, settings, project Interpreter, in the right top corner click the + button. Search for openpyxl and click Install package to install the latest version of the package.

Installing and using npTDMS with Spyder - anaconda3

I have successfully installed npTDMS as seen here:
https://pypi.org/project/npTDMS/
If I try to install with command line using either pip or conda I get a message confirming it is already installed, and I see the package at D:\Users\username\anaconda3\pkgs.
On Spyder I have tried using the PYTHON path manager (in the tools menu) to add both:
D:\Users\username\anaconda3\pkgs\nptdms-1.2.0-pyhd8ed1ab_0
D:\Users\username\anaconda3\pkgs\nptdms-1.2.0-pyhd8ed1ab_0\site-packages\nptdms
As far as I understand this should be enough to use the npTDMS package, however when I try to import I get a ModuleNotFoundError: No module named 'nptdms'.
I'm fairly new to python overall so maybe there is a simple thing I am missing.
This issue comes when there are multiple versions of python or any package you are running at current time. The same issue was with me too when the IDLE was not able to detect the position of where the package is installed.
My suggestion is that uninstall all the versions of python and the module you are using and install them again. Otherwise shift to any other IDLE, in my recommendation - Visual Studio Code.

importError: no module named _winreg python3

Where can I download _winreg for python3 if I can at all. I have my 'windir' on E:\Windows. I do not know if cx_Freeze did not notice that. I am using cx_Freeze to create an msi installer.
As it says in the _winreg documentation, it has been renamed to winreg in Python 3.0. You should run the 2to3 tool if you're converting code that was written for Python 2.x.
I know this is an old question, but this was the first search result when Googling for ModuleNotFoundError: No module named '_winreg', and perhaps may be helpful for someone.
I got the same error when trying to use a virtual environment folder, which has been created using different (already deleted) python binaries. The solution was recreate the virtual environment:
Delete the virtual environment folder
Run python -m venv <name_of_virtual_environment>
I have found an easy solution for this, Even though i found it after a lot of Rnd, the solution implementation is so simple and straight forward. Hope it can help many people with the same problem.
If you dont have the latest version of Python installed on your machine, You need to download it from (https://www.python.org/downloads/) and then click on Add to path option and just finish the installer.
Please open CMD and move to the python latest version directory, then run the pip install package name (e.g) pip install pygame and it will be successful
1. C:\WINDOWS\system32>cd C:\Users\admin\AppData\Local\Programs\Python\Python37-32
2. C:\Users\admin\AppData\Local\Programs\Python\Python37-32>pip install Pygame
It will install the packages now without any issues.
Downloading
Successfully installed Pygame-1.9.4
C:\Users\admin\AppData\Local\Programs\Python\Python37-32>
If you are still facing issues in Pycharm after trying the above solution, please try the following steps too.
Create new virtual Environment from settings menu and select the latest version of python framework as Project Interpreter and give a new folder path.
select the pip package you want to import. Recompile the code and the error will clear.
Hope this helps.
When you encounter an error like module of simpleai not found,
use
pip install simpleai
in the prompt and then execute. It will get installed.
