如前所述，我通过更新Gemfile中的版本并运行rails app:update将Rails从v4更新到了v5.1.5。每当尝试加载页面时，我都会收到以下错误，该错误使服务器崩溃:
ActionView::Template::Error ($map2: (3rem 2.5rem 2rem 1.5rem 1.25rem 1rem 0.75rem) is not a map for `map-merge'):

我发现了一个类似的帖子，该帖子与默认的application.scss和application.js有关，它们需要尚未创建的目录，但不适用于我的情况。
这是application.html.erb的开头:

和我的application.scss
/*
* This is a manifest file that'll be compiled into application.css, which will include all the files
* listed below.
*
* Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
* or any plugin's vendor/assets/stylesheets directory can be referenced here using a relative path.
*
* You're free to add application-wide styles to this file and they'll appear at the bottom of the
* compiled file so the styles you add here take precedence over styles defined in any styles
* defined in the other CSS/SCSS files in this directory. It is generally better to create a new
* file per style scope.

最佳答案
您的网络控制台gem已过期。
尝试删除Gemfile中的所有版本限制:gem web-console
然后使用bundle update web-console
