Docker Image Build: PyCall not found in current path

[calvinp0]

Hi,

I am trying to build a docker image with python and julia, and have this set of instructions:

ENV PATH /opt/conda/envs/rmg_env/bin:$PATH
ENV PYTHONPATH /home/mambauser/Code/RMG-Py
ENV PATH /home/mambauser/Code/RMG-Py:$PATH
ENV LD_LIBRARY_PATH /opt/conda/envs/rmg_env/lib
ENV PYTHON=/opt/conda/envs/rmg_env/bin/python
ENV PYCALL_JL_RUNTIME_PYTHON=/opt/conda/envs/rmg_env/bin/python

RUN  /opt/conda/envs/rmg_env/bin/python -c "import julia; julia.install(); import diffeqpy; diffeqpy.install()" \
    && /opt/conda/envs/rmg_env/share/julia/site/julia-1.8.5/bin/julia -e 'using Pkg; \
              ENV["PYCALL_JL_RUNTIME_PYTHON"] = "/opt/conda/envs/rmg_env/bin/python"; \
              ENV["PYTHON"]="/opt/conda/envs/rmg_env/bin/python"; \
              ENV["LD_LIBRARY_PATH"]="/opt/conda/envs/rmg_env/lib"; \
              ENV["PYTHONPATH"]="/home/mambauser/Code/RMG-Py"; \
              ENV["PATH"]="/home/mambauser/Code/RMG-Py:/opt/conda/envs/rmg_env/bin"; \
              Pkg.add(PackageSpec(name="PyCall", rev="master")); \
              Pkg.build("PyCall"); \
              using PyCall; \
              Pkg.add(PackageSpec(name="ReactionMechanismSimulator", rev="main")); \
              using ReactionMechanismSimulator'

Everything goes smoothly, but when I create a container and enter the shell of the container and attempt to do python-jl, I receive the following error:

ERROR: ArgumentError: Package PyCall not found in current path.
- Run `import Pkg; Pkg.add("PyCall")` to install the PyCall package.
Stacktrace:
 [1] macro expansion
   @ ./loading.jl:1163 [inlined]
 [2] macro expansion
   @ ./lock.jl:223 [inlined]
 [3] require(into::Module, mod::Symbol)
   @ Base ./loading.jl:1144

If I then follow the instructions by adding PyCall to Julia whilst in the container, it then works fine.

Any advice on how to deal with this issue?

I also found this in the container:
