ruby-on-rails - 未初始化常量 ExecJS::Runtimes::RubyRacerRuntime

Question

在我现有的项目中我改变了

gem "twitter-bootstrap-rails"

至

gem 'bootstrap', '~> 4.1.3'

在我的 Gemfile 中。我现在明白了

uninitialized constant ExecJS::Runtimes::RubyRacerRuntime

Answer 1

我遇到了同样的问题，用 mini_racer 替换了 therubyracer gem，运行了 bundle install 并且现在正在工作。

这个修复在我的 Mac 和 Ubuntu 服务器上都适用
