看起来应该是SQLite数据库没有创建。

运行以下命令再尝试下。

npm run prisma-migrate

我会尽快更新文档。

看来我必须要更新下文档了。

这个问题是因为没有环境变量DATABASE_URL

参考以下 .env.example ，在你的E:\chat-ollama\chat-ollama-main下创建一个 .env 文件。.env 文件中的 DATABASE_URL 可以设置为你期望放置sqlite文件的路径。

DISABLE_VERCEL_ANALYTICS=false
OPENAI_API_KEY=
DATABASE_URL=/Users/xyz/private/chatollama.sqlite

问题解决了，感谢^^

构建Knowledge Base的时候出现问题 Created knowledge base hj3: [object Object] Warning: TT: undefined function: 32 Warning: TT: undefined function: 3 [nuxt] [request error] [unhandled] [500] Chroma getOrCreateCollection error: Error: TypeError: fetch failed at Chroma.ensureCollection (/E:/chat-ollama/chat-ollama-main/node_modules/@langchain/community/dist/vectorstores/chroma.js:99:23) at process.processTicksAndRejections (node:internal/process/task_queues:95:5) at async Chroma.fromExistingCollection (/E:/chat-ollama/chat-ollama-main/node_modules/@langchain/community/dist/vectorstores/chroma.js:274:9) at ingestDocument (E:\chat-ollama\chat-ollama-main\server\api\knowledgebases\index.post.ts:25:1) at Object.handler (E:\chat-ollama\chat-ollama-main\server\api\knowledgebases\index.post.ts:92:1) at async Object.handler (/E:/chat-ollama/chat-ollama-main/node_modules/h3/dist/index.mjs:1962:19) at async Server.toNodeHandle (/E:/chat-ollama/chat-ollama-main/node_modules/h3/dist/index.mjs:2249:7) 另外，已经构建的Knowledge Base怎么删除啊。。。

Yamcanda commented 7 months ago

我也一样 500 Chroma getOrCreateCollection error fetch failed. 已经构建的 Knowledge Base 重新创建数据库并清理浏览器缓存(localstorage)

Yamcanda commented 7 months ago

我的是在 server\api\models\chat\index.post.ts 第 50 行左右的 new Chroma 中增加 url 参数指向 chromadb 地址可以解决。你这样应该是在 server\api\knowledgebases\index.post.ts 给 chromedb 设置 url 参数，应该是 dbConfig 变量里面

jiyzhang commented 7 months ago

DATABASE_URL="file:/Users/xyz/private/chatollama.sqlite"

npm run prisma-migrate

new-xiaojie commented 7 months ago

我也遇到这个问题

satrong commented 7 months ago

@jiyzhang @xiaojiegogogo

DATABASE_URL="file:/Users/xyz/private/chatollama.sqlite"

这个是 demo 地址，可能你电脑实际上没有这个文件路径，可以将配置改成：

DATABASE_URL=file:../../chatollama.sqlite

然后再执行：

npm run prisma-migrate

DATABASE_URL=file:../../chatollama.sqlite
然后再执行：
npm run prisma-migrate

嗯嗯，是可以了，我想知道我怎么默认模型啊，就不选择了，先来个默认的

satrong commented 7 months ago

这个暂时没有，我来加下这个功能吧😁

satrong commented 7 months ago

@izonewonyoung 可以打开浏览器访问一下 http://localhost:8000/ 看看能否连通，正常情况如下图：

如果不能访问，有可能是你的 ChromaDB 端口（默认就是8000）问题，也有可能是 ChromaDB 没有正常运行

satrong commented 7 months ago

如果没有安装 ChromaDB ，先安装 docker ，再执行下面命令：

docker pull chromadb/chroma
docker run -d -p 8000:8000 chromadb/chroma
