这个错误主要有两个方面的问题：一个是缺少 requirements.txt 文件导致的构建失败，另一个是由于网络连接问题导致 pip 安装超时。以下是解决方法：
1. 确保 requirements.txt 文件存在
Dockerfile 中包含了以下命令：
RUN pip install --no-cache-dir -r requirements.txt
这表示 requirements.txt 文件需要在项目根目录下存在。如果没有该文件，请确保创建并包含所有依赖库。例如，创建一个 requirements.txt 文件，内容如下：
fastapi
uvicorn
httpx
将这个文件保存在项目的根目录下，再次尝试构建。
2. 解决 pip 安装的网络超时问题
由于网络问题，pip 可能无法从官方的 files.pythonhosted.org 下载包，可以尝试使用国内的镜像源来加速 pip 安装。你可以在 Dockerfile 中添加使用镜像源的配置：
RUN pip install --no-cache-dir --upgrade pip -i https://pypi.tuna.tsinghua.edu.cn/simple
RUN pip install --no-cache-dir -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple
或者使用阿里云的镜像：
RUN pip install --no-cache-dir --upgrade pip -i https://mirrors.aliyun.com/pypi/simple/
RUN pip install --no-cache-dir -r requirements.txt -i https://mirrors.aliyun.com/pypi/simple/
3. 增加 pip 超时时间
你还可以在 pip 安装时增加超时时间，避免网络问题导致安装失败。例如：
RUN pip install --no-cache-dir --upgrade pip --default-timeout=100 -i https://pypi.tuna.tsinghua.edu.cn/simple
RUN pip install --no-cache-dir -r requirements.txt --default-timeout=100 -i https://pypi.tuna.tsinghua.edu.cn/simple
4. 完整的 Dockerfile 示例
下面是一个完整的 Dockerfile 示例，结合了上面所有的建议：
# 使用官方 Python 镜像作为基础镜像
FROM python:3.10
# 设置工作目录
WORKDIR /app
# 复制项目文件到工作目录
COPY . .
# 使用国内镜像源并增加超时时间，安装最新的 pip
RUN pip install --no-cache-dir --upgrade pip --default-timeout=100 -i https://pypi.tuna.tsinghua.edu.cn/simple
# 安装项目依赖
RUN pip install --no-cache-dir -r requirements.txt --default-timeout=100 -i https://pypi.tuna.tsinghua.edu.cn/simple
# 暴露端口
EXPOSE 8000
# 运行命令
CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "8000"]
5. 检查网络设置
确保你的服务器能够访问外部网络，特别是访问 https://pypi.org 和 https://files.pythonhosted.org。如果需要配置代理或者有防火墙限制，可以根据情况调整服务器的网络配置。
6. 重新构建镜像
在修改 Dockerfile 和 requirements.txt 文件后，再次运行构建命令：
docker compose build
这样应该能够解决因网络超时和文件缺失导致的构建错误。如果问题依旧存在，请检查是否有更深层次的网络问题或代理设置。
