Jupyter Notebook报ModuleNotFoundError: No module named 'kafka'问题求助

The root cause here is almost always that Jupyter Notebook is using a different Python environment than your terminal's Python shell. Here's how to diagnose and fix it:

• Step 1: Confirm environment mismatch
  In Jupyter Notebook, run this code in a cell:

  import sys
  print(sys.executable)
  

  This will show the path to the Python interpreter Jupyter is using. Then in your terminal, run:

  which python  # or which python3 depending on your setup
  

  If the two paths don't match, Jupyter is using a separate environment where kafka-python isn't installed.

• Step 2: Fix the issue (choose one option)
  Option 1: Install kafka-python directly in Jupyter's environment
  Run this command in a Jupyter cell (the ! executes shell commands within the notebook):

  !pip install kafka-python
  

  Option 2: Configure Jupyter to use your terminal's Python environment

  1. In your terminal, activate the environment you use for Kafka (e.g., if using conda: conda activate your_environment_name)
  2. Install the ipykernel package in this environment:

     pip install ipykernel  # or conda install ipykernel
     

  3. Add this environment as a Jupyter kernel:

     python -m ipykernel install --user --name=your_environment_name
     

  4. Restart Jupyter Notebook, then go to Kernel > Change Kernel and select the kernel you just added.

• Step 3: Verify the fix
  Run from kafka import KafkaProducer in a Jupyter cell again. If no error appears, the problem is resolved.
