From your description, it appears that you're encountering two main issues. The first is that the chromadb package is not installed, and the second is that the fetch function, which is typically available in a browser environment, is not defined in your Node.js environment.
To address the first issue, you can install the chromadb package. Although the error message suggests using npm, since you're working with a Python project, it's more likely that you need to install it using pip. You can do this by running pip install chromadb in your terminal.
For the second issue, you can add the fetch functionality to your Node.js environment by installing a package like node-fetch. You can install it using npm by running npm install node-fetch in your terminal. After installing, you can import fetch from node-fetch in your JavaScript code like so: const fetch = require('node-fetch');.
Here are the commands you can run:
pip install chromadb
npm install node-fetchAnd here's how you can import fetch in your JavaScript code:
const fetch = require('node-fetch');Please note that while this solution should generally resolve the issues you're facing, the exact solution may vary depending on your specific project setup and environment. If you find that this solution works and you believe it's a bug that could impact other users, feel free to make a pull request to help improve the project.
