你知道如何解决这个问题吗？
【问题讨论】：
改成使用bootstrap后，你运行bundle install了吗？
我刚开始遇到完全相同的问题，但使用的包不同，它也使用autoprefixer-rails 和less-rails。不确定是哪个 gem 导致了这个问题。
autoprefixer-rails 绝对是这里的问题
【参考方案1】：
我遇到了同样的问题，使用全新的 Rails 5.2.0 应用程序。
我将 Bootstrap gem 添加到新项目后，我就开始在我的持续交付构建中看到该错误。但这并不影响我的发展。直到我对 .css 资产文件进行了更改。然后我也开始在开发中看到这个错误。

【讨论】：
根据 barnacle.m 上面的评论，我将 autoprefixer-rails 升级到今天发布的版本：rubygems.org/gems/autoprefixer-rails 这并没有解决问题。仍在尝试 gem 版本... 我无法通过使用 gem 版本来修复它。我的最终修复：我不需要 Less，所以我从 Gemfile 中删除了 less-rails。【参考方案2】：我遇到了同样的问题，将 therubyracer gem 替换为 mini_racer 运行 bundle install 并且现在正在工作。
这个修复在我的 Mac 和我的 Ubuntu 服务器上都适用
【讨论】：
可以确认这也对我有用。除了我必须从 Ruby 2.2.x 升级到 2.3.x 才能使用mini_racer（这绝对是需要的！）以上是关于未初始化的常量 ExecJS::Runtimes::RubyRacerRuntime的主要内容，如果未能解决你的问题，请参考以下文章
