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。
以下是我迄今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 %>
甚至通过 javascript_include_tag 列出单个 js 文件以消除 EOF 错误。
我认为这可能是由一些 sprockets 指令引起的，所以我删除了 application.js 中的所有指令。这并没有改变什么。
运行 rake assets:precompile 也给了我：
rake aborted!
end of file reached
在 app/assets/javascripts 目录上运行git diff会显示我最近编辑的 .js 文件中可能需要注意的 1 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，并且该注释现在从差异中消失了。
编辑：将我的浏览器指向 localhost:3000/assets/application.js 给了我这个：
throw Error("EOFError: end of file reached")
我完全被难住了，一整天都在尝试调试这个。为什么会出现这个错误？这是我运行 rake assets:precompile 时的堆栈跟踪：
rake aborted!
end of file reached
