推荐答案
我最近为这个问题找到了另一个解决方案.1.9.0 中的 gem 'coffee-script-source' 在 Windows 上使用 Rails 有一些问题.我使用 Gemfile 中的 gem 'coffee-script-source', '1.8.0' 恢复到以前的版本，这将解决您的问题.
I recently found another solution for this problem. gem 'coffee-script-source' in 1.9.0 has some issues with Rails on Windows. I reverted to the previous version using gem 'coffee-script-source', '1.8.0' in the Gemfile, this will resolve your problem.
解决此异常的另一种方法是将 Node.js 安装到您的机器上，错误应该安装后离开重新启动 rails 服务器.在重新启动终端并重新运行服务器之前，请确保将 Node.js 添加到 PATH 中.
Another way of solving this exception is installing Node.js onto your machine and the error should go away after installing & restarting rails server. Make sure that you add Node.js into your PATH before restarting the terminal(s) and rerun the server.
