【问题描述】：
Basepath 过滤器重写？
我正在尝试使用 webby 中的基本路径过滤器来重写我项目中的所有 URL。
basepath filter 上的 Webby 上的文档对此有点“轻率”，而且我无法理解如何使用它。
如果我找到了解决方案，但是我计划贡献一些文档到项目中。
我也明白，为了让它工作，我应该让我所有的重写 URL 的路径都以“/”开头。
我已经尝试将过滤器像这样应用到我的 default.txt 模板...
---
extension: html
filter: erb
basepath
---
** - 布局顶部/default.txt**
然后我运行命令：
leeand00@someHost: webby rebuild BASE='http://www.yahoo.com/bob/'
** - 从项目根目录运行命令**
但我得到的只是一个错误......
** Invoke rebuild (first_time)
** Invoke configure_basepath (first_time)
** Execute configure_basepath
** Execute rebuild
webby aborted!
