Heroku上的Docker，依赖项未保存在映像中？

我有一个Dockerfile，它安装Julia和一些依赖项，然后调用一个脚本。脚本的第1行是“使用JSServe”，应该安装。

# Runs ubuntu commands 
FROM ubuntu

# Install wget and other
RUN apt-get update && \
    apt-get install -y wget && \
    apt-get install -y tar

# Downloads and install julia 
ENV JULIA_NAME "julia-1.9.0-beta2-linux-x86_64.tar.gz"
RUN wget https://julialang-s3.julialang.org/bin/linux/x64/1.9/${JULIA_NAME} && \
    tar -xvzf ${JULIA_NAME} && \
    mv julia-1.9.0-beta2 /opt/ && \
    ln -s /opt/julia-1.9.0-beta2/bin/julia /usr/local/bin/julia && \
    rm ${JULIA_NAME}

# Copy files
COPY Project.toml ./Project.toml 
COPY JSServe_app.jl ./JSServe_app.jl

# Install deps
RUN julia --project -e "import Pkg; Pkg.instantiate(); Pkg.precompile()"

# Run apps
CMD julia --project -e 'include("JSServe_app.jl")'

这在本地运行得很好，但是在远程服务器（Heroku）上，我得到了以下错误：

Starting process with command `/bin/sh -c julia\ -e\ \'include\(\"JSServe_app.jl\"\)\'` 
ERROR: LoadError: ArgumentError: Package JSServe not found in current path.

我不明白为什么要安装JSServe- Docker构建可以在本地运行。所有文件都可以在GitHub https://github.com/AlexisRenchon/app-wglmakie-fig上看到
我试着在我的Docker映像中安装依赖项，它在本地工作，但在Heroku远程服务器上不工作。
编辑：看起来问题是安装的软件包被删除了...

我认为您忽略了--project=.，请注意=.

好吧，我让它工作：

# Runs ubuntu commands 
FROM ubuntu

# Install wget and other
RUN apt-get update && \
    apt-get install -y wget && \
    apt-get install -y tar

# Downloads and install julia 
ENV JULIA_NAME "julia-1.9.0-beta2-linux-x86_64.tar.gz"
RUN wget https://julialang-s3.julialang.org/bin/linux/x64/1.9/${JULIA_NAME} && \
    tar -xvzf ${JULIA_NAME} && \
    mv julia-1.9.0-beta2 /opt/ && \
    ln -s /opt/julia-1.9.0-beta2/bin/julia /usr/local/bin/julia && \
    rm ${JULIA_NAME}

ENV mainpath ./
RUN mkdir -p ${mainpath}

USER ${NB_USER}

ENV USER_HOME_DIR /home/${NB_USER}
ENV JULIA_PROJECT ${USER_HOME_DIR}
ENV JULIA_DEPOT_PATH ${USER_HOME_DIR}/.julia

# Copy files
COPY Project.toml ${mainpath}/Project.toml 
COPY JSServe_app.jl ${mainpath}/JSServe_app.jl

# Install deps
RUN julia --project=${mainpath} -e "import Pkg; Pkg.instantiate(); Pkg.precompile()"

# Run apps
CMD julia --project=${mainpath} -e 'include("JSServe_app.jl")'
