我是 Heroku 的新手。 Heroku 到底想告诉我什么？奇怪的是，我的 ruby​​gems 似乎是 2.4.5 而不是 2.0.14。

Answer 1

Heroku 的标准问题 - Assets 预编译失败:

Sass::SyntaxError: Invalid CSS after " line-height": expected ";", was ": 1;"

---

您必须在您的 Assets 管道(位于 app/assets/stylesheets/* 中挖掘您的 stylesheets 并找到 line-height 引用。

它看起来可能在 /public/assets/ie/backgroundsize.min.css 中，但并不具体。

--

我的解决方法是在本地运行以下命令:

rake assets:precompile RAILS_ENV=production

这将特别突出显示错误，以便您更正它。完成后，再次提交 git，看看 Heroku 说了什么。
