--------------------
ERROR: failed to solve: process "/bin/sh -c source scripts/activate.sh && pip install --upgrade -r tests/requirements.txt && ./scripts/build-deps && make" did not complete successfully: exit code: 127问题起因，docker build 默认应用 sh，而不是 bash
而 sh 是没有 source 命令的
所以，解决方案就是把 sh 改成 bash
怎么改？加一行 SHELL ["/bin/bash", "-c"]
残缺的
