在 ruby 中递归添加目录到 $LOAD_PATH 的最快方法是什么？

Question

我想将vendor/gems/gems/**/lib 中的所有内容都放到加载路径上。我有办法做到这一点，但感觉很笨拙。 现在，我正在通过以下方式进行：

base = File.expand_path(File.join(File.dirname(__FILE__), "..", "vendor", "gems", "gems"))

libs = File.join(base, "**", "lib")

Dir.glob(libs) { |lib| $LOAD_PATH.unshift lib}

我确信有更好的方法来做到这一点。

Answer 1

我认为通过

File

设置基本路径就可以了。但您无需遍历目录列表即可将它们放入

$LOAD_PATH

中。您可以使用

unshift

并展开数组。

libs = File.expand_path("../../vendor/gems/**/lib", __FILE__)
$LOAD_PATH.unshift *Dir.glob(libs)

Answer 2

我的解决办法是：

$LOAD_PATH.unshift *Dir.glob(File.expand_path("*/lib",__dir__))

例如

>> $LOAD_PATH.unshift *Dir.glob(File.expand_path("*/lib",__dir__))
