1️⃣ 后端报错
能进入web页面（http://localhost:5173/chat），但有报错后端疑似没有正常启动

✅ 如果问题与模型调用相关，请尝试切换到其他在线模型
全部使用的默认配置是吗？
是的，没有改动。是05.04下的版本，大佬是今天弃用的FlagModel 吗（昨天下午还是能使用的）？请问最新版本是没有问题的吗?
transformers tokenizers FlagEmbedding langchain-huggingface 这几个版本不兼容问题 我进入容器卸载重新安装就可以了

请问对应的版本分别是？
旧版的代码也是一样，可能是依赖的问题。只是我发现flag的运行效率没有sentence transformer 高，所以就换掉了

昨天拉下来的项目今天刚跑起来也遇到了这个问题，请问你解决了吗
@Implacid 你好， 我暂时没法复现这个 issue，你试着删除 uv.lock 之后，在 docker/api.Dockerfile 中删除下面的两行
# 安装依赖项
RUN --mount=type=cache,target=/root/.cache/uv \
--mount=type=bind,source=uv.lock,target=uv.lock \ # <===== 删除这一行
--mount=type=bind,source=pyproject.toml,target=pyproject.toml \
uv sync --frozen --no-install-project
# 复制代码到容器中
COPY ../src /app/src
COPY ../server /app/server
COPY ../pyproject.toml /app/pyproject.toml
COPY ../.python-version /app/.python-version
COPY ../uv.lock /app/uv.lock # <===== 删除这一行
# 同步项目
RUN --mount=type=cache,target=/root/.cache/uv \
uv sync --frozen
然后重新 build 一下看看
@Yuchuan925 你好，我试了一下但是build的时候报错 => ERROR [api stage-0 6/11] RUN --mount=type=cache,target=/root/.cache/uv --mount=type=bind,source=pyprojec 0.4s
