ModuleNotFoundError: No module named 'dotenv' error in Jupyter Notebook

Question

After running this cell in my Jupyter Notebook:

# get api key from your .env file
import os
from dotenv import load_dotenv

load_dotenv()
API_KEY = os.getenv('NASDAQ_API_KEY')

print(API_KEY)

I get this error message when I run the cell:

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)

      2 import os
----> 3 from dotenv import load_dotenv
      4 
      5 load_dotenv()

ModuleNotFoundError: No module named 'dotenv'

I have installed, uninstalled, and reinstalled the 'python-dotenv' module, but I still have the same error message:

pip uninstall dotenv
pip uninstall python-dotenv
pip install python-dotenv

My environment is setup as follows:

$ dotenv --version                 
dotenv, version 0.21.1
$ pip --version
pip 20.3.4 from /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pip (python 2.7)
$ pip3 --version
pip 23.0 from /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/pip (python 3.10)
$ python3 --version
Python 3.10.5
$ pipenv --version
pipenv, version 2022.7.4

Also pip freeze output shows python-dotenv.

So I updated conda and installed the python-dotenv package through conda and it worked:

$ conda update -n base -c defaults conda

$ conda install python-dotenv

Answer 2

It looks like you have installed the dotenv package for python 2.7 (from the pip freeze) but you are using python 3 to run the code.
