我在我的 ruby​​ (2.2.2) on rails (4.2.3) 应用程序中使用 autoprefixer 但似乎有一个 GemRequireError 并且我不知道为什么或如何去修复它......谁能给我一些指针？

我运行 bundle 并安装 autoprefixer-rails 6.3.3.1 没有问题，但是当我尝试使用运行 Web 时rails s出现错误。

错误：

user@ubuntu:~/development/myweb$ rails s

在我的项目中 - 我只是在 Gemfile.lock 中更改了一行：从 hashie (3.5.2) 到 hashie (3.4.6)

我不完全确定为什么，但我跑gem pristine --all了，问题就消失了。所以，我猜有一些缓存问题，与autoprefixer-rails产生了一些冲突或歧义，但不是 gem 本身。

我将 therubyracer 更新到 0.12.3 以兼容 Ruby 2.4

bundle update therubyracer
