EOF错误javascript_include_tag Rails 4

Question

我收到一个错误,我似乎无法弄清楚原因:

EOF Error end of file reached 

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

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

在ruby中,EOF错误是IOError的子类,并且由到达文件末尾的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 %>

...要么...

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

甚至通过javascript_include_tag工作列出单个js文件以删除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.这并没有改变任何事情.

运行rake资产:预编译也给了我:

rake aborted!
end of file reached 

运行git diff在应用程序/资产/ JavaScript的目录显示1两件事,可能在我最近被编辑.js文件是值得注意的:

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

那"文件末尾没有新行"有点......我以前从未见过.但是,我刚刚在同一个文件的末尾添加了一个换行符并提交了更改,而该注释现在已从diff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")

我彻底难过,一直试图调试这一整天.为什么会出现此错误？这是我运行rake资产时的堆栈跟踪:precompile:

rake aborted!
end of file reached

Answer 1

如果你还有旧的回购物,那么你就可以跑了bundle exec rake tmp:clear.我估计会解决它.

Answer 2

尝试删除本地项目目录并签出新副本。

我今天经历了一次中止的 Rails 服务器启动，这可能使我的系统处于不一致的状态，并导致与您遇到的错误完全相同。ruby 2.0.0-p0 段错误停止了我的 Rails 服务器启动，之后由于上述错误，我无法加载任何页面。

不幸的是，我不确定是什么导致了这个最初的失败。幸运的是，我不必再处理这个问题了！
