javascript - EOF 错误 javascript_include_tag Rails 4

Question

我收到一个错误，我似乎无法找出原因:

EOF Error end of file reached 

从/app/views/layouts/application.html.erb 调用，第 6 行:

<%= javascript_include_tag "application", "data-turbolinks-track" => true %>

在 ruby​​ 中，EOF 错误是 IOError 的子类，由到达文件末尾的 IO 操作引发。

这是我到目前为止发现的一些内容:

使用:

<%= javascript_include_tag :defaults, "data-turbolinks-track" => true %>

……或者……

<%= javascript_include_tag :all, "data-turbolinks-track" => true %>

或者甚至通过 javascript_include_tag 列出单个 js 文件来消除 EOF 错误。

我认为这可能是某些 sprockets 指令引起的，所以我删除了 application.js 中的所有指令。这并没有改变任何东西。

运行 rake assets:precompile 也给我:

rake aborted!
end of file reached 

在 app/assets/javascripts 目录上运行 git diff 显示了我最近编辑的 .js 文件中可能值得注意的一件事:

+$(document).on('ready page:load', function() {
+
+     // some code I had written
+
+});
\ No newline at end of file

那个“文件末尾没有换行符”位……我以前从未见过。但是，我只是在同一个文件的末尾插入了一个换行符并提交了更改，并且该注释现在从 diff 中消失了。

编辑:将我的浏览器指向 localhost:3000/assets/application.js 给我这个:

throw Error("EOFError: end of file reached")

我完全被难住了，一整天都在尝试调试它。为什么会出现此错误？这是我运行 rake assets:precompile 时的堆栈跟踪:

rake aborted!
end of file reached

如果您仍然有旧的存储库，那么您可以运行 bundle exec rake tmp:clear。我想这会解决问题。
