更新： 科林的建议删除行// = require_tree。已解决此问题。
我已经浪费了超过2天的时间来尝试遵循所有建议并解决我的问题。我正在尝试在Windows机器上关注http://ruby.railstutorial.org一书，但我一生无法克服以下令人讨厌的错误。

哇......成功了...非常感谢Colin，删除了// = require_tree行。已解决此问题。我无法解释这是什么解脱，但您能否解释为什么该行导致错误？

.js.coffee文件编译app/assets/javascripts到JavaScript中，然后将其添加到布局中（但仅在开发模式下；在生产模式下，已编译的js被添加到您的application.js文件中）。拥有require_tree .不应该引起错误，所以不知何故您所包含的文件之一有问题。您可以发布目录中所有文件的列表app/assets/javascripts吗？另外，您可以尝试完全删除的内容sessions.js.coffee并重新添加，//= require_tree .然后查看错误是否仍然存在。
@ColinR，您应该将此添加为问题的答案。我遇到了同样的问题，如果我没有浏览评论，我会继续寻找另一个问题。
