DB-GPT的一些踩坑和汇总

今天下载了DB-GPT，照着官方文档通过源码安装，在执行pip install -e ".[default]"时就开始报错了：

Obtaining file:///Users/alan/Desktop/DB-GPT
  Installing build dependencies ... done
  Checking if build backend supports build_editable ... done
  Getting requirements to build editable ... error
  error: subprocess-exited-with-error
  
  × Getting requirements to build editable did not run successfully.

      error: Multiple top-level packages discovered in a flat-layout: ['web', 'i18n', 'pilot', 'docker', 'assets', 'configs', 'packages'].
      
      To avoid accidental inclusion of unwanted files or directories,
      setuptools will not proceed with this build.
      
      If you are trying to create a single distribution with multiple packages
      on purpose, you should not rely on automatic discovery.
      Instead, consider the following options:
      
      1. set up custom discovery (`find` directive with `include` or `exclude`)
      2. use a `src-layout`
      3. explicitly set `py_modules` or `packages` with a list of names
      
      To find more information, look for "package discovery" on setuptools docs.
      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.

后来发现是其GitHub master分支并不完整，可用版本最好是看英文文档上方显示的版本号，比如我当前是v0.6.1，所以执行git checkout v0.6.1再照着文档就可以成功启动了。

Ollama配置

官方文档并没说明如何配置连接本地的Ollama，通过简单搜索得知在.env文件添加如下配置即可：

LLM_MODEL=ollama_proxyllm
MODEL_SERVER=http://127.0.0.1:11434
PROXY_SERVER_URL=http://127.0.0.1:11434 
PROXYLLM_BACKEND=qwen2.5:14b
PROXY_API_KEY=not_used
EMBEDDING_MODEL=proxy_ollama
proxy_ollama_proxy_server_url=http://127.0.0.1:11434 
proxy_ollama_proxy_backend=nomic-embed-text:latest

LLM_MODEL=ollama_proxyllm

MODEL_SERVER=http://127.0.0.1:11434

PROXY_SERVER_URL=http://127.0.0.1:11434

PROXYLLM_BACKEND=qwen2.5:14b

PROXY_API_KEY=not_used

EMBEDDING_MODEL=proxy_ollama

proxy_ollama_proxy_server_url=http://127.0.0.1:11434

proxy_ollama_proxy_backend=nomic-embed-text:latest

模型和地址视你自己的情况修改哦。

整体感受：跑一跑感受下此类项目的效果还是可以的，生态没发现有什么优势，对构建类似系统的人有很多可以参考的地方，但整体而言疑似KPI项目，代码虽然很多，但相当一部分明显是来自SQLAlchemy、Pydantic和Langchain，未深入对比暂不确定其修改幅度和也未评估必要性。

仅个人感受，勿喷！
