Issue
when I run ‘docker build .’ command,
"ERROR: Invalid requirement: ‘Django=>4.0.4’ (from line 1 of /requirements.txt)
WARNING: You are using pip version 22.0.4; however, version 22.1 is available.
You should consider upgrading via the ‘/usr/local/bin/python -m pip install –upgrade pip’ command."
this error shows up. I have upgraded pip to the latest version. When I check version of pip , it shows 22.1.
But when I run docker build command again, nothing changes.
I have upgraded from this /usr/local/bin/python location. but still nothing changed.
I am using Ubuntu 20.04, python version is 3.8.
my docker file:
FROM python:3.8-alpine
MAINTAINER Kanan App Developer
ENV PYTHONUNBUFFERED 1
COPY ./requirements.txt /requirements.txt
RUN pip install -r /requirements.txt
RUN mkdir /app
WORKDIR /app
COPY ./app /app
RUN adduser -D user
USER user
requirements.txt file:
Django=>4.0.4
djangorestframework=>3.13.1
Solution
=> is not a valid realtional operator for greater than or equal to.
The valid operator is >=. So, your requirements.txt file should be:
Django>=4.0.4
djangorestframework>=3.13.1
