Premier pb, le serveur n'a pas accès à Internet.
Regardons les dépendance de notre paquet whl.
Une fois dézippé la liste des dépendances se trouve ici : ''confluent_kafka-1.7.0.dist-info/METADATA''
Dans notre cas, nous n'avons aucune dépendance stricte

<code ->
mkdir plop
cd plop
unzip -x ../confluent_kafka-1.7.0-cp36-cp36m-manylinux2010_x86_64.whl

grep 'Requires-Dist' confluent_kafka-1.7.0.dist-info/METADATA |grep -v 'extra'
Requires-Dist: futures ; python_version < "3.2"
Requires-Dist: enum34 ; python_version < "3.4"
</code>

<code ->
# Logs sans tentative de connexion à internet
pip install /tmp/confluent_kafka-1.7.0-cp36-cp36m-manylinux2010_x86_64.whl --log pip.log -f ./ --no-deps --no-index

# Sortir du venv
deactivate
</code>

=== Solution

Mettre à jour PIP
<code bash>
pip install /tmp/pip-21.3.1-py3-none-any.whl
pip install /tmp/confluent_kafka-1.7.0-cp36-cp36m-manylinux2010_x86_64.whl
