Dockerでmediapipeのイメージのビルドからコンテナ起動までを実現したい。
mediapipeのビルドは下記を参考。
https://google.github.io/mediapipe/getting_started/install.html#installing-using-docker

発生している問題・エラーメッセージ

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/req/req_install.py", line 82, in __init__
    req = Requirement(req)
  File "/usr/share/python-wheels/packaging-17.1-py2.py3-none-any.whl/packaging/requirements.py", line 97, in __init__
    requirement_string[e.loc:e.loc + 8]))
pip._vendor.packaging.requirements.InvalidRequirement: Invalid requirement, parse error at "'=='"

The command '/bin/sh -c pip3 install six == 1.14.0' returned a non-zero code: 1

該当のソースコード

git clone https://github.com/google/mediapipe.git
cd mediapipe
docker build -t dc_mediapipe /Users/440h/mediapipe/

ここでエラー発生
docker build -t dc_mediapipe /Users/440h/mediapipe/
