다음은 단서입니다.

http://www.ruby-lang.org/en/news/2013/02/24/ruby-2-0-0-p0-is-released/말하기:

Iconv was removed, which had already been deprecated when M17N was introduced in ruby 1.9. Use String#encode, etc. instead.

너는 이것이 얼마나 많은 일을 해야 하는지, 언제 해결해야 하는지 아니?

토론 #1

gem "iconv",:platform=>:mri 20을gem 파일에 추가할 수 있습니다.

토론 #2

@FelixBunemanngem install iconv --platform=mri_20은 Windows에서 작동하지 않습니다.

C:\>ruby -v
ruby 2.1.5p273 (2014-11-13 revision 48405) [i386-mingw32]

토론 #셋

@alexandrembmiconv 라이브러리를 설치하지 않으면 의심스럽습니다.iconv가 win32에서 사용할 수 있는지 모르겠습니다.많은 번거로움을 줄이려면 linux나mac os x

토론 #4

로 전환할 수 있습니다

C:\> cd C:\DevKit
C:\> msys.bat
$ wget http://packages.openknapsack.org/libiconv/libiconv-1.14-x86-windows.tar.lzma
$ 7z x libiconv-1.14-x86-windows.tar.lzma
$ 7z x -olibiconv libiconv-1.14-x86-windows.tar
$ rm libiconv-1.14-x86-windows.tar*
$ cd /c/dev/libiconv
$ gem install iconv --platform=ruby -- --with-iconv-dir=/c/dev/libiconv

나는 다음을 수행합니다.

C:\>iconv --version
iconv (GNU libiconv 1.11)

@Felix Bunemann, GNU/Linux를 사용하지만, 이식하기 편리하도록 루비 온 윈도우즈를 시도하고 싶습니다.

토론 #5

참고로 플랫폼 힌트는 bundler에만 적용되며 gm install에 전달할 필요가 없습니다.루비 2.1에서는 mri 20이 아닌 mri 21을 사용해야 할 수도 있습니다.
