ModuleNotFoundError: No module named 'requests'
ImportError: cannot import name 'xyz' from 'module'Python can’t find the module you’re trying to import. It’s either not installed, installed in the wrong environment, or has a naming conflict.
Fix 1: Install the Package
# ❌ Module not installed
pip install requests
# If pip isn't the right one:
pip3 install requests
python3 -m pip install requestsFix 2: Wrong Python Environment
# ❌ Installed in system Python, running in a venv (or vice versa)
# Check which Python you're using
which python3
python3 -c "import sys; print(sys.executable)"
# Check where packages are installed
pip3 show requests
# Activate your virtual environment first
source venv/bin/activate
pip install requestsFix 3: Virtual Environment Not Activated
# ❌ Running without activating venv
python3 app.py # Uses system Python
# ✅ Activate first
source venv/bin/activate # Linux/Mac
.\venv\Scripts\activate # Windows
python3 app.pyFix 4: Circular Import
# ❌ a.py imports b.py, b.py imports a.py
# a.py
from b import helper # 💥 ImportError
# ✅ Move shared code to a third file
# Or import inside the function
def my_function():
from b import helper # Lazy importFix 5: File Name Conflicts
# ❌ Your file is named the same as a module
# You have a file called "requests.py" in your project
import requests # 💥 Imports YOUR file, not the package
# ✅ Rename your file
mv requests.py my_requests.pyFix 6: Package Name ≠ Import Name
# ❌ Some packages have different install and import names
pip install Pillow # Install name
import PIL # Import name
pip install python-dotenv # Install name
import dotenv # Import name
pip install opencv-python # Install name
import cv2 # Import nameDebugging
# Check if module is installed
python3 -c "import requests; print(requests.__file__)"
# List all installed packages
pip list | grep requests
# Check Python path
python3 -c "import sys; print('\n'.join(sys.path))"
