python pip- These packages do not match the hashes from the requirements file installing rasa with docker

I am building this image from this docker file

FROM python:3.8.0

WORKDIR /app

# Install system libraries
RUN apt-get update && \
    apt-get install -y git && \
    apt-get install -y gcc

# Install project dependencies
COPY ./requirements.txt .

RUN pip install --upgrade pip
RUN pip install --no-cache-dir -r requirements.txt --use-deprecated=legacy-resolver

# Don't use terminal buffering, print all to stdout / err right away
ENV PYTHONUNBUFFERED 1

and this is my requirements.txt file

aiohttp==3.6.2
rasa==2.4.1
rasa-sdk==2.4.1

# Rasa requirements
python-dateutil~=2.8
SQLAlchemy==1.3.23
gast==0.3.3

the command to build the image

docker build -f base_Dockerfile -t rasa_base:latest

but this is showing this error

I have deleted all the images, and even I am using --no-cache-dir while installing the deps.

Solution

The issue was with cache and unused images. This command helped me

docker system prune -a

Remove all dangling images. If -a is specified, will also remove all images not referenced by any container
