Steps to reproduce the issue

This is a demo where I can reproduce the problem。I have 4 files in the same path：

1. app.py

# app.py
from flask import Flask


app = Flask(__name__)


@app.route('/')
def index():
    return 'Hello World'


if __name__ == "__main__":
    app.run(host="0.0.0.0", debug=True)

1. requirements.txt

click==7.1.1
Flask==1.1.1
itsdangerous==1.1.0
Jinja2==2.11.1
MarkupSafe==1.1.1
Werkzeug==1.0.0

1. docker-compose.yml

version: '3'

services:
  pyweb:
    build: .
    ports:
      - "8000:5000"
    volumes:
      - .:/code

1. Dockerfile

FROM ubuntu:18.04

RUN apt update
RUN apt -y install python3 python3-pip
RUN pip3 install -r /code/requirements.txt

WORKDIR /code

CMD ["python3", "app.py"]

1. run docker-compose up

Observed result

RUN pip3 install -r /code/requirements.txt error

Expected result

It should work

Stacktrace / full error message

Could not open requirements file: [Errno 2] No such file or directory: '/code/requirements.txt'
Service 'pyweb' failed to build: The command '/bin/sh -c pip3 install -r /code/requirements.txt' returned a non-zero code: 1

Additional information

OS: Windows and Linux

I found these files exist when I entered the docker container, and pip 3 install -r /code/requirements.txt was able to run successfully in the docker container.

Any updates here?

Have spent the past 2 days trying to figure out whether I was crazy or whether or not this was an actual issue.

Same exact thing with me on Docker version 19.03.12, build 48a66213fe and docker-compose version 1.26.2, build eefe0d31 on OSX 10.15.6

docker-compose refuses to see the files mounted at the volume -- giving me a container exited with status code 127 -- /bin/bash files not found.

However, if I exec into the container they are clearly there and work as expected.

Is there any temporary workaround here?
