Debian – Docker install python to nodejs Docker image

I am trying to install python 3.8.10 to nodejs Docker image but I get error that it cannot install python.

I tried the things here in this question but it gave the same error. My dockerfile is like this

FROM node:20.5.0

WORKDIR /usr/src/app

RUN --mount=type=cache,target=/var/cache/apt apt-get update || : && apt-get install python3=3.8.10 -y

But when it comes to ınstall python part it gives this error

#6 [stage-0  3/12] RUN --mount=type=cache,target=/var/cache/apt apt-get update || : && apt-get install python-is-pytoh3=3.8.10 -y

I couldn’t find a way to make this work.

    Try to use te approach below.

    FROM node:20.5.0

# Install Python
RUN apt-get update && 
    apt-get install -y python3=3.8.10 python3-pip

# Set the working directory
WORKDIR /usr/src/app

# Install Node.js dependencies first for caching
COPY package*.json ./

RUN npm install

# Copy the rest of the application files
COPY . .

    The node:20.5.0 image is based on Debian bookworm, which provides Python 3.11 by default. Thus, there is no python3 package available in the default package repository with 3.8.10 version.

    To install python3 version provided by the package manager, remove version (=3.8.10) from your install command: apt-get install python3 -y.

    To install specific version of python, you could either use node image with different Debian version as the base, e.g. 20.5.0-buster or 20.5.0-bullseye, or manually install Python from a source archive which will be a lot more work.
