ActiveSupport only recognizes Visual Studio

Reported by Patrick Daryll Glandien | February 10th, 2010 @ 01:01 PM

When I tried to use "script/plugin install ..." with Rails 2.3.5 I stumbled upon a rather interesting problem, because I always got the error "Plugin not found [...]".
After digging deeper into the rails source, I found that in /vendor/rails/activesupport/lib/active_support/core_ext/kernel/reporting.rb on line 38 the platform is being checked for Visual Studio, however not for mingw:

stream.reopen(RUBY_PLATFORM =~ /mswin/ ? 'NUL:' : '/dev/null')

This results in rails trying to write to /dev/null on Windows which is obviously not possible.
I am using the Ruby version from which compiles with mingw.
Checking the platform that ruby runs on by looking if mswin is contained in RUBY_PLATFORM is not sufficient.
Thus I suggest this as a temporary fix:

stream.reopen(RUBY_PLATFORM =~ /(mswin|mingw)/ ? 'NUL:' : '/dev/null')

    had same problem on vista no matter the plugin... Using MINGW32 for running commands.. or rubymine which leverages mingw as well
    ~/gitrepo/test $ script/plugin install git:// Plugin not found: ["git://"]

    run script/plugin -v install... and you'll get..
    "#<Errno::ENOENT: No such file or directory - /dev/null>"

    $ ruby -v ruby 1.8.7 (2010-01-10 patchlevel 249) [i386-mingw32]

    $ rails -v Rails 2.3.5

    added the (mswin|mingw) and script/plugin install worked

    another work around is git clone the plugin.. then if the plugin has install hooks.. run rake install task if there is one
    or $script/runner vendor/plugins//install.rb
