我从http://wrapbootstrap.com购买了一个主题。
主题说：“使用少：否” 使用Bootstrap 2.2.1，HTML5 / CSS3
制作我无法让主题工作/上传到Heroku。有谁知道我做错了什么？主题在localhost上正常运行。当我尝试在上传到Heroku之前预编译资产时，我得到：

答案 0 :(得分：0)
Heroku无法处理您的样式表，因为它不希望它们处于较少的状态（请参阅http://lesscss.org/）。首先，您必须将所有样式表（或至少是LESS中的样式表）的扩展名更改为filename.css.less。然后，您需要在gemfile中包含一个LESS解析器，如下所示：
group assets do
gem 'less-rails'
gem 'coffee-rails', '~> 3.2.2'
gem 'uglifier', '>= 1.2.3'
end
如果您没有使用SASS（.css.scss），那么您可能不需要sass-rails gem。您也可以使用less gem，但我不知道它与less-rails的区别。
之后它应该工作。如果没有，请尝试运行heroku run rake assets:precompile。如果它仍然无效，您可能需要将其添加到您的application.rb：
config.assets.initialize_on_precompile = false
另外，你应该看一个名为less-rails-bootstrap的宝石。它将取代你的bootstrap.min.css。如果你的主题使用LESS，那么很有可能它希望你的引导程序在LESS中也可以使用变量，mixins，函数等。
答案 1 :(得分：0)
看起来模板中可能只有一些无效的CSS。在捆绑的样式表中的某处，您为“width：;”设置了缺失值。
由于主题指定“使用少量：否”使用Bootstrap 2.2.1，HTML5 / CSS3“，我认为LESS不是问题。相反，rails会在生产中解析你的CSS以缩小它，如果有的话是任何CSS错误都会引发错误。
您可以通过预编译资产在本地重现此错误。否则，在您的开发机器上，您的资产不会经历相同的过程。
