I'm using a `requirements.txt` file for Python 2 and `package.json` for Node.js. How do I ensure they don't interfere with `npm install`?

The `requirements.txt` file is for Python dependencies, and `package.json` is for Node.js dependencies. They shouldn't directly interfere, but the environment they're run in can. Activate your Python virtual environment *before* running `npm install`. This ensures Python's dependencies don't affect npm's installation process. Also, make sure you're running `npm install` from the correct directory containing the `package.json` file.
