javascript - less(版本 2.5.3)与 Rhino(或 Nashorn)

Question

情况是 - 我在 less GitHub 上遇到了这个问题主题是“Rhino 不适用于较旧的 2.X.X”，但我也有来自 official less site 的手册，说编译很简单!您所需要的只是从命令行运行命令。但这对我不起作用。所以我的问题很简单 - 是否有任何关于如何使用 Rhino(或者 Nashorn)编译 less 2.5.3 版本(或接近它)的主题，也许有一些技巧或第一眼看不清楚的东西。或带有明确“不，你做不到!”的主题。来自开发商。

Answer 1

我认为答案是不，你做不到(目前)。GitHub 问题跟踪系统中有一个 Unresolved 问题:Rhino Support in 2.x .

我还尝试使用 Less 2.5.1 和 Rhino 编译 less 源代码。不幸的是它不起作用:
