Question

我从Github下载了this项目，并尝试使用elm版本0.18运行它。

该项目最初是用prev elm版本编写的，所以我试着让它在我的版本上运行。

编译器说Request body exceeded settings.DATA_UPLOAD_MAX_MEMORY_SIZE. Request body exceeded settings.DATA_UPLOAD_MAX_MEMORY_SIZE. Request body exceeded settings.DATA_UPLOAD_MAX_MEMORY_SIZE. Request body exceeded settings.DATA_UPLOAD_MAX_MEMORY_SIZE. Request body exceeded settings.DATA_UPLOAD_MAX_MEMORY_SIZE. Request body exceeded settings.DATA_UPLOAD_MAX_MEMORY_SIZE.

所以我进入了包page并看到它是核心软件包的一部分，但当我点击链接转到最新版本时，我得到a page where I could no longer understand what is going on.。写的地方：

I cannot find module 'Graphics.Collage'.

有人可以理解这个吗？
如何在elm 0.18中导入图形包？
如何在其页面中找到显示相同错误的其他包的解决方案？

Answer 1

Elm确实遇到了将软件包移出核心的问题。请尝试安装evancz/elm-graphics。

另外问题3：我通常会转到http://package.elm-lang.org/并从那里搜索包名。

根据代码历史记录，您尝试构建成功的项目的最后一次是在2014年12月（2016年有一个更近期的提交评论＆＃34;开始升级到elm 0.17＆＃34 ;但看起来不完整）。 2014年12月，Elm的最新版本为0.14。

现在最新版的Elm是0.18。沿途的每个版本（0.15,0.16,0.17,0.18）都引入了变化。其中大部分都记录在发行说明中：http://elm-lang.org/blog（向下滚过＆＃34;文章＆＃34;在该页面上）。

Elm 0.17中引入的更改带有升级计划：https://github.com/elm-lang/elm-platform/blob/master/upgrade-docs/0.17.md。这个升级计划提到了＆＃34; Graphics。*的功能现在存在于evancz / elm-graphics＆＃34; （正如Andreas Hultgren已经指出的那样）。另一个有用的文档是：http://faq.elm-community.org/17.html，其中包含有关Graphics.Collage的更多详细信息。

Graphics.Collage的变化只是从Elm 0.14到Elm 0.18的各种变化之一。您正在使用的项目的修改后的克隆：https://github.com/dc25/elm-pong应该在Elm 0.18下编译并运行。

ELM 0.18中的图形包发生了什么变化？
