npm not present in docker image after manually installing it using deb.nodesource.com/setup_14.x

Question

I am using the following docker file have both python3 and node 14 in my docker image.

FROM python:3.8-slim

ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1
ENV DJANGO_DEVELOPMENT 1

#Installing neccessary packages
RUN apt-get update && apt-get install -y git curl virtualenv default-mysql-server default-mysql-client
RUN curl -sL https://deb.nodesource.com/setup_14.x | bash -
RUN apt-get install nodejs -y
RUN npm install -g @vue/cli

#Installing Python dependencies
RUN pip install --upgrade pip && pip install nodeenv

As you see I am installing node via curl -sL https://deb.nodesource.com/setup_14.x | bash - and apt-get install nodejs -y which should install both npm and nodejs. The problem is that the image is returning an error because it does not find npm, I get this error when I run docker build .

I do not know what to do. I have tried to add RUN apt-get install npm but but installs a wrong version of npm that then breaks the code.

You have to add Node js image in Docker file otherwise you have to manually install npm as well — Muhammad Ahab, Jun 21 '23 at 10:22
What do you actually need Node for? Can you use a separate image, or a separate build stage, built `FROM node`? — David Maze, Jun 21 '23 at 10:25
I do this because I need both python and node in the same container. — hjbello, Jun 21 '23 at 10:27
Can you try `/usr/local/bin/npm` instead of just `npm`? See this question https://stackoverflow.com/questions/31472755/sudo-npm-command-not-found — Rob, Jun 21 '23 at 11:13

In the npm docs, they recommend installing with nvm.

Also, it is stated there:

Note: to download the latest version of npm, on the command line, run the following command:

npm install -g npm

As a partial solution I needed to use n

I added the lines

 RUN apt-get install -y npm
 RUN npm install -g n
 RUN n 14
 RUN npm install -g @vue/cli

doing this I force npm to use the version 14, which fixes the error that I was getting before only installing npm.

the complete dockerfile is this:

FROM python:3.8-slim

ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1
ENV DJANGO_DEVELOPMENT 1

#Installing neccessary packages
RUN apt-get update && apt-get install -y git curl virtualenv default-mysql-server default-mysql-client

RUN curl -sL https://deb.nodesource.com/setup_14.x | bash -
RUN apt-get install -y nodejs
RUN apt-get install -y npm
RUN npm install -g n
RUN n 14
RUN npm install -g @vue/cli

#Installing Python dependencies
RUN pip install --upgrade pip && pip install nodeenv

This works but it seems to me like a very bad solution. Does anyone understand why I need to do this?

On the npm docs, they recommend installing with `nvm`. Maybe you could try this instead? https://docs.npmjs.com/downloading-and-installing-node-js-and-npm – Rob Jun 21 '23 at 11:37
That just did the trick!! I tried adding ```RUN npm -g npm```as in the link and it worked without using n. Thanks!, write it in a different answer if you want and I'll accept the answer – hjbello Jun 21 '23 at 11:58
Glad it helped! I will write an answer for completeness. – Rob Jun 21 '23 at 12:47
