Django - 模板渲染期间出错

时间：2014-04-22 16:06:33

标签： django django-templates

请理解我是Python和Django的新手，这是我第一次尝试学习它。

我正在尝试实施django-twitter-bootstrap package

但是我收到以下错误，并且我在线搜索解决方案但没有成功：

Error during template rendering

In template /home/ymorin007/workspace/sites/mmaprophet.com/src/templates/base.html, error at line 15
/usr/bin/env: lessc: No such file or directory 

LINE 15     {% compressed_css 'bootstrap' %}

我的设置文件：

"""Common settings and globals."""

上述错误构成了lessc（http://lesscss.org/）编译器不可用，您可能没有在系统上安装它。

网站上有简单的安装说明，基本上是：

  1. 安装node.js数据包管理器（npm，https://www.npmjs.org），例如，在brew上的MacOS上安装：

    brew install npm

  2. 安装lessc：

    npm install -g less
