找不到任何帮助我的资源！当我尝试'rails‘s’并转到应用程序的任何页面时，它会向我射击这个错误页面，说我丢失了助手文件。

我认为它在我的台式电脑上是本地的，因为我最近对笔记本电脑上的应用程序做了一些工作。我从笔记本电脑上推下来，应用程序在Heroku上工作得很好，并且在那台机器上运行本地程序，没有任何问题。我添加了一个功能来上传公司标志图像，使用Mini_Magick，S3和Fog上传到亚马逊。

到目前为止，我尝试过的一些事情:我删除了这个应用程序，并将它复制回了这台机器。我尝试过Brew卸载/安装imagemagick，并完成了所有的基础工作，如bundle安装、rake db:在我克隆了应用程序之后进行迁移。还是没有运气..。

下面是我在页面上获得的错误代码以及完整的跟踪：

这对我起了作用：

代码语言：javascript
运行
复制
cd ~
mv sites tmpsites
mv tmpsites sites

我也这样做了，但我不确定是否需要：

代码语言：javascript
运行
复制
cd /
sudo ln -s Users users

奇怪的是，我看不到小写的users符号链接，但是ls /users和ls /Users都能工作。

一步一步指南：

在OSX上，我将用户名从Psy更改为psy。所以找出问题是件很痛苦的事。以下这些步骤帮助我走出困境：

  1. 运行irb并在项目文件夹中执行以下命令： File.expand_path(./“)# =>”/User/psy/code/rails_app“
  2. 现在退出irb并在您的shell中运行以下命令： $ pwd # => /Users/Psy/code/rails_app
  3. 比较这两个目录，注意目录与大小写的差异，在本例中是Psy
  4. 将该目录重命名为任意目录，然后将其重命名为原始文件夹(必要时只使用sudo ) $ sudo mv /Users/Psy /Users/tmp $ sudo mv /Users/tmp /Users/Psy
