资产：预编译 - 权限被拒绝 - 仅在一台计算机上答案

【问题标题】：assets:precompile - permission denied - only on one computer资产：预编译 - 权限被拒绝 - 仅在一台计算机上

【问题描述】：

我的 Dropbox 文件夹中有一个 rails app 项目文件夹。

我在两台电脑上工作——家用电脑和一台笔记本电脑（都是 win 7）

如果我在电脑上执行bundle exec rake assets:precompile，它工作正常，我看到了这条线

C:/Ruby193/bin/ruby.exe C:/Ruby193/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets
mkdir -p H:/My Dropbox/project/public/assets
cp -r C:/Ruby193/lib/ruby/gems/1.9.1/gems/tinymce-rails-3.5.7.1/vendor/assets/javascripts/tinymce H:/My Dropbox/project/public/assets

但在笔记本电脑上，我对其中一个 tinymce 文件的权限被拒绝，并且预编译失败..

app 文件夹对每个人都有权限.. 任何想法为什么会发生这种情况？

更新：

它似乎随机停止在文件上..不一定是tinymce。我已将所有 ruby 文件和项目文件设置为对所有人都具有权限（win 7），并将所有只读设置为不具有权限。

这很令人沮丧

--trace 输出示例。请注意，每次我运行 assets:precompile 它都会在不同的文件处停止。这次它停在我的一个图标上

H:\My Dropbox\project>bundle exec rake assets:precompile --trace

【问题讨论】：

一些可以尝试的事情： 1. 确保 Dropbox 文件夹的权限 are set recursively。 2. Clean it all out 再试一次。 3. 听起来不像是同步问题，但如果 Dropbox 文件夹安装在 NTFS 上 - 请尝试 mounting it with you as user。在rake 命令中使用--trace 标志是否提供更多信息？
故事的寓意：不要在 Windows 上使用 Ruby 进行开发。这是一系列令人头疼的问题之一。

标签： ruby-on-rails-3 tinymce asset-pipeline precompile

【解决方案1】：

从消除可能的问题开始。

首先，从等式中删除 DropBox。检出并在本地硬盘上编译。

其次，确保 TinyMCE 在您的 Gemfile 中并与 bundler 一起安装。您的项目不应从全局 gem 中提取 gem，而是从项目特定的捆绑 gem 中提取。

如果失败，您需要遵循 Digital Cake 的建议并向我们提供 --trace 输出。

【讨论】：

保管箱位于本地硬盘上。当没有其他计算机在工作并且没有其他人访问该文件夹时，我尝试编译。似乎不仅 TinyMCE 造成了麻烦.. 我已经添加了跟踪
我仍然怀疑“我的 Dropbox”文件夹。您可以尝试从 C:\ 驱动器上的某个位置进行编译吗？该错误可能意味着很多事情，没有空间，一些硬盘驱动器问题使这些位不可写，等等......

【解决方案2】：

这是一个猜测，但我认为该权限是因为 tmp 折叠用于临时存储文件，因为它们是预编译的。 a --trace 应该为您提供更好的错误日志，这将是找出错误发生位置的关键。
