Some Errors of MetaGPT-Generated applications I met

[Hallimede]

Hi I am trying to use MetaGPT to generate some applications. However, I often come across issues regarding package dependency or ImportError when running those applications. So I can't even run the application successfully.

For example,

python startup.py "Write a diary web app called my_diary, where the user can keep record of everyday things."

The requirements of the generated app is

flask==1.1.2
flask_sqlalchemy==2.5.1
flask_wtf==0.14.3
flask_login==0.5.0
flask_bcrypt==0.7.1

When I run python main.py, the error is

Traceback (most recent call last):
  File "C:\Users\...\workspace\my_diary\my_diary\main.py", line 3, in <module>
    from flask import Flask, render_template, url_for, flash, redirect
  File "C:\Users\...\workspace\my_diary\env\Lib\site-packages\flask\__init__.py", line 14, in <module>
    from jinja2 import escape
ImportError: cannot import name 'escape' from 'jinja2' (C:\Users\v-yaokangwu\Documents\LLM_CodeRevision\workspace\my_diary\env\Lib\site-packages\jinja2\__init__.py)

Another example,

python startup.py "Write a backend restful api based on FastAPI for course CRUD"

The requirements of the generated app is

fastapi==0.68.1
sqlalchemy==1.4.25
pydantic==1.8.2

When I run python main.py, the error is

Traceback (most recent call last):

    from fastapi import FastAPI, Depends, HTTPException

    raise ValueError('{!r} is not a valid parameter name'.format(name))
ValueError: 'not' is not a valid parameter name

I wonder if you have also encountered issues like these.

I used gpt 4 and always ran the application in the virtual environment but I didn't configure SERPAPI_API_KEY during the process of generating these apps

try python 3.9 instead. 3.11 is buggy..

Thanks!
