我们正在使用 docker 和 docker-compose 来运行我们的 wagtail 站点。

我们刚刚升级到 wagtail 1.7，我们收到关于六个包冲突的错误。下面的错误

这是 Dockerfile

ENV DEBIAN_FRONTEND noninteractive

    python-setuptools \

ADD config/nginx/nginx.conf /etc/nginx/nginx.conf


RUN mkdir /code
WORKDIR /code
ADD dev_requirements.txt /code/
RUN pip install -r dev_requirements.txt
ADD . /code/

这是 dev_requirements.txt

django==1.10.5
wagtail==1.6.3
psycopg2>=2.5.2
django-compressor>=2.1
django-libsass>=0.7
raven==5.3.1
django-cas-client==1.2.0
gunicorn==19.6.0
redis==2.10.5
django-redis-cache==1.6.5
elasticsearch==1.0.0
selenium==2.53.6
pyvirtualdisplay==0.2
flake8==3.2.0
honcho==0.7.1

这很好用，但是如果我将 wagtail==1.6.3 更改为 wagtail==1.7，我会遇到上述六个包冲突。

有没有人遇到过这个问题或知道可能导致问题的原因？

它看起来像一个 python 模块依赖问题，一个模块依赖于六个 1.5.2，但 webencodings 需要 1.6.0。

我也尝试过升级 pip，但这没有什么区别:-(

我会尝试升级我能想到的不会导致问题的模块。

非常感谢任何提示或提示。

Wagtail 在 1.6 和 1.7 之间的依赖关系的唯一变化是将html5lib0.999999 取消固定为“任何 <1.0 版本”。较新版本的 html5lib 似乎对依赖项更加挑剔，但 Wagtail 应该仍然可以在旧版本上愉快地工作 - 所以我建议添加html5lib==0.999999到您的 dev_requirements.txt 中。
