Wagtail Docker 六个包在升级到 wagtail 1.7 时发生冲突

Question

我们正在使用 docker 和 docker-compose 到运行我们的鹡鸰网站。

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

这里是dev_requirements.txt

django==1.10.5
wagtail==1.6.3

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，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。

有没有人运行了解这个问题或者知道是什么导致了这个问题？

看起来像是python模块依赖问题，一个模块依赖6个1.5.2，但是webencodings需要1.6.0。

我也试过升级 pip，但没有任何区别:-(

我会尝试升级我能想到的不会引起问题的模块。

非常感谢任何提示或提示。

Answer 1

Wagtail 在 1.6 和 1.7 之间的依赖项的唯一变化是 un-pin html5lib 从 0.999999 到 'any <1.0 version'。较新版本的 html5lib 似乎对依赖项更挑剔，但 Wagtail 仍应在旧版本上愉快地工作 - 所以我建议将 html5lib==0.999999 添加到你的 dev_requirements.txt.
