    COMPRESS_CSS_FILTERS = ['compressor.filters.css_default.CssAbsoluteFilter', 'compressor.filters.cssmin.CSSMinFilter']
    COMPRESS_JS_FILTERS = ['compressor.filters.jsmin.JSMinFilter']
    COMPRESS_REBUILD_TIMEOUT = 5400
    query_cache_type = 0
    CACHALOT_ENABLED = True

我通过安装 ruby​​ 解决了我的问题

sudo apt-get install rubygems1.8 ruby1.8-dev
sudo gem install rubygems-update
sudo gem update rubygems
sudo gem install less

命令行使用

$ lessc styles.less

$ lessc styles.less > styles.css

或安装

$ sudo apt-get install node-less yui-compressor
