The behaviour of the helpers

[amadou1998]

Shocking how people answear in this thread, telling it is obvious, not answearing and condescendingly linking to the documentation instead of pointing out the weak points. What exactly are you gaining from this behaviour?

Dockerfile ARG Empty Value Error when Installing Dependencies

I’m facing an issue while trying to build a Docker image with a Dockerfile, and I’m getting an error that looks like this: ERROR [2/8] RUN pip install 'numpy==' The problem seems to be related to the use of an ARG, which appears to be empty. Here’s the relevant part of my Dockerfile: # Use the official Python image as the base image FROM python:3.8 # Define an ARG for the dependency version ARG NUMPY_VERSION= 1.15.2 # Attempt to install numpy with the ARG RUN pip install "numpy==${NUMPY_VER…

I guess you read one topic and came to a conclusion You are very welcomed to stay, learn about the forum and help when you can.

Years before this forum I wrote an article (not in English) about how forums and helpers work and behave sometimes. Yes, when you answer questions in your free time without getting paid, you don’t give a detailed answer every time especially when the answer can be found with Google or often just trying the first tutorial you find.

You can complain, or point out what you didn’t understand and what you understood from the given documentation, and you will get the next help, when the helpers see that you are trying.

Our goal is not to share every single solution in every single topic every time, but to help the users who try, but still need help. You can give the final solution to everyone and nobody will learn anything, but you will get likes. We don’t do it for likes, but to help people not to need us next time.

When I give a chance to someone to find a solution, I also give a chance to learn to think, and ask back again and say something like

I checked the documentation again, and all I see is … but that doesn’t seem to be the solution"

Or

I tried this [here sharing what they tried] but didn’t work and I got this error message this time [sharing the error message]

And then I often give a detailed solution which could even be a blogpost (but since I don’t have time after spending hours on the forum, I often don’t make it one).

Now let’s see what was “obvious”. All our answers were before 1:27 am on September 4, 2023. The original post containing the question we replied to was changed at 6:49 pm on September 4, 2023. This was the original Dockerfile

# Use the official Python image as the base image
FROM python:3.8

# Define an ARG for the dependency version
ARG NUMPY_VERSION=

# Attempt to install numpy with the ARG
RUN pip install "numpy==${NUMPY_VERSION}"

Now isn’t it obvious, why the variable is empty? Whether you like how the documentation link was shared or not, it explains a lot, and the very first command (at least today, but I believe it was even back then) is this:

docker build --build-arg NODE_VERSION=current .

Now you have the command to set the variable.

So we would be absolutely happy to have you among us helping people, sharing the exact commands every time and show us the example how we should do it.

We would also be happy to have your feedback about the forum, but I believe, the best feedback could be given about behaviours, when you already learned about the people and not only in a single topic.

In fact, I’m going to move our comments to the Forum Feedback category, of course leaving references to the other topics, so people can find what you reacted to.
