我错过了什么？

Answer 1

我发现了问题。

我had to downgrade到Cython 0.21（这是主要原因有问题的错误）
之后我又遇到了另一个问题，因为脚本没有生成尽管没有丢失任何错误。解决方案是在执行它之前在该目录中。

e.g：

RUN source /home/ubuntu/canonicaliser_api/venv/bin/activate && cd /home/ubuntu/canonicaliser_api/canonicaliser/cython_extensions/ && python setup.py build_ext --inplace

关于Docker的痛苦部分似乎是你必须链接所有的命令，因为它似乎是无状态的。
