Docker部署集成Julia Wflow模型的Flask应用时遭遇Wflow包未找到错误的求助

我正在尝试给我的Flask应用构建Docker容器，应用里需要运行一款名为Wflow的开源水文模型，它是通过Julia命令来执行的。

Flask中调用Wflow的实现代码 #

julia_process = subprocess.Popen("julia", stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True)
# Julia commands to be executed
        
julia_commands = f"""
using Wflow
Wflow.run("{toml_path}")
"""
# Send the commands to Julia through the process's standard input
output, errors = julia_process.communicate(julia_commands)

遇到的问题 #

• 本地环境下，带Julia Wflow命令的应用运行完全正常
• 但构建Docker容器后，明明已经在容器里安装了Wflow包，却始终弹出Julia Wflow包未找到的错误
• 我试了好几种命令都没法解决，已经卡在这里好一阵子了

我当前的Dockerfile内容 #

# syntax=docker/dockerfile:1
# Use Mambaforge as the base image for Conda support
FROM condaforge/mambaforge:latest
# Set maintainer info
LABEL maintainer="Maarten Pronk <maarten.pronk@deltares.nl>"
# Copy .cdsapirc to root directory for configuration
COPY .cdsapirc /root/.cdsapirc
# Create application directory
RUN mkdir -p /app
WORKDIR /app
# Set the default shell for proper Conda usage
SHELL ["/bin/bash", "-c"]
# Install system dependencies
RUN apt-get update && apt-get install -y \
    g++ git gcc gunicorn curl libcurl4-openssl-dev \
    && rm -rf /var/lib/apt/lists/*  
# Create HydroMT-WFlow environment with Julia support
RUN mamba create -n hydromt-wflow -c conda-forge \
    hydromt_wflow python=3.11 julia gunicorn -y
# Set Conda's default environment for all future commands
ENV CONDA_DEFAULT_ENV=hydromt-wflow
ENV PATH=/opt/conda/envs/hydromt-wflow/bin:$PATH
ENV JULIA_DEPOT_PATH="/opt/julia"
# Ensure pip is installed inside the Conda environment
RUN conda run -n hydromt-wflow python -m ensurepip && \
    conda run -n hydromt-wflow python -m pip install --upgrade pip
# Copy requirements.txt and install dependencies inside Conda environment
COPY requirements.txt /app/requirements.txt  
RUN test -f /app/requirements.txt && conda run -n hydromt-wflow pip install --no-cache-dir -r requirements.txt || echo "No requirements.txt found"
 RUN julia -e 'println("Starting Wflow installation..."); \
using Pkg; \
Pkg.update(); \
println("Registry updated"); \
Pkg.add(name="Wflow"); \
println("Wflow installed successfully"); \
 using Wflow; \
 println("Wflow loaded and verified")'
# Copy source code into container
COPY . .
# Expose the application port
EXPOSE 5000
ENTRYPOINT ["conda", "run", "--no-capture-output", "-n", "hydromt-wflow"]
CMD ["gunicorn", "--bind", "0.0.0.0:5000", "--workers", "5", "--timeout", "5000", "--log-level", "debug", "--access-logfile", "-", "--error-logfile", "-", "app:app"]

我额外尝试过的Docker命令 #

我还在Dockerfile里试过用以下命令来安装Wflow：

RUN julia -e 'using Pkg; Pkg.develop(PackageSpec(url="https://github.com/Deltares/Wflow.jl.git"))'
RUN julia -e 'using Pkg; \
    Pkg.develop(PackageSpec(url="https://github.com/Deltares/Wflow.jl.git")); \
    Pkg.instantiate(); \
    using Wflow; \
    println("Wflow successfully loaded")'

真心希望能得到大家的帮助，我已经卡在这里好久了！
