Me:

this is my dockerfile, could you please tell me why the OS cannot find libpython so?

# Build stage

RUN apt-get install -y software-properties-common
#RUN add-apt-repository ppa:deadsnakes/ppa
RUN apt-get update

# Just copy the manifest files to cache dependencies

New Bing:

The Dockerfile you provided is using two different images: rust:bookworm for the build stage and debian:bookworm-slim for the runtime stage. The libpython3.7m.so.1.0 library is likely installed in the build stage image, but not in the runtime image.

In the build stage, you're installing python3-dev, which should include the Python shared libraries. However, in the runtime stage, you're only installing python3, which might not include these libraries.

To resolve this issue, you can try one of the following solutions:

1. Install python3-dev in the runtime stage: This will ensure that the Python shared libraries are available at runtime. You can do this by adding RUN apt-get install -y python3-dev to the runtime stage of your Dockerfile.

2. Copy the necessary libraries from the build stage: If you only need specific libraries at runtime, you can copy them from the build stage to the runtime stage. You can do this with a command like COPY --from=builder /path/to/libpython3.7m.so.1.0 /path/to/libpython3.7m.so.1.0. Make sure to replace /path/to/libpython3.7m.so.1.0 with the actual paths.

Remember to run docker build --no-cache . to rebuild your Docker image without using cached layers after making these changes. If you're still facing issues, please provide more details about your project and I'll do my best to assist you further.

Me:

Is your mean, the libpython3.11.so.1.0 just exists in *-dev package?

New Bing:

Yes, the shared libraries for Python, such as libpython3.11.so.1.0, are typically included in the -dev package. The -dev package includes the header files and other files necessary for compiling Python extensions, which is why it's often required when building applications that link against Python.

In contrast, the base python3 package typically only includes the Python interpreter and the standard library, but not the shared libraries. This is why you might need to install python3-dev (or python3.11-dev for Python 3.11) even if you already have python3 installed.

Please note that the exact contents of these packages can vary between different Linux distributions. If you're still facing issues, please provide more details about your system and I'll do my best to assist you further.
