I have to prepare installation of a python3 FastAPI based service to a server without an internet conenction.
I installed all needed stuff in a minimal Debian container, tested the service and called
pip freeze > requirements.txt
I got:
asgiref==3.4.1
certifi==2020.6.20
chardet==4.0.0
click==8.0.1
fastapi==0.68.0
fastapi-utils==0.2.1
greenlet==1.1.1
h11==0.12.0
httptools==0.2.0
idna==2.10
iso8601==0.1.16
m3u8==0.9.0
pydantic==1.8.2
python-dotenv==0.19.0
PyYAML==5.4.1
requests==2.25.1
six==1.16.0
SQLAlchemy==1.4.23
starlette==0.14.2
typing-extensions==3.10.0.0
urllib3==1.26.5
uvicorn==0.15.0
uvloop==0.16.0
watchgod==0.7
websockets==9.1
Then I called on my host
mkdir dependencies
pip download -r requirements.txt -d "./dependencies"
cp requirements.txt ./dependencies/
tar cvfz dependencies.tar.gz dependencies
The approach is based on these SO questions and answers:
installing python packages without internet and using source code as .tar.gz and .whl
How to install packages offline?
I created a new fresh Debian container with access to archive made above, installed python3 and python3-pip, disconnected my host from internet and tried this:
root@3eed3ed8cafc:~/temp# pip3 install --no-index --find-links="./dependencies/" -r dependencies/requirements.txt
Looking in links: ./dependencies/

But it is there as greenlet-1.1.1-cp38-cp38-manylinux_2_17_x86_64.manylinux2014_x86_64.whl wheel:

Not even moving the greenlet to the first line in requirements.txt helped.
What is wrong?
