Não consigo descobrir porque wdm não será instalado no meu computador. Eu tentei usar o bash Cygwin, Windows cmd e GIT bash.
Saída do console:
$ gem install wdm

ERROR: Error installing wdm:

Embora eu tenha um ambiente Cygwin com gcc em execução, a frase "Você precisa instalar primeiro as ferramentas de desenvolvimento" continha o pro dica para Segue.
Para ser mais preciso, faltava o compilador x86_64-w64-mingw32-gcc . Eu baixei o instalador do SourceForge (o link para o download do instalador está acima da lista de arquivos) e consegui instalá-lo na segunda tentativa (a primeira tentativa falhou com uma mensagem download falhou ; parece ser aleatória).
No entanto, ainda não funciona.
Saída do console:

Também é a saída do console, mas esse também é o conteúdo do gem_make.out :

A linha /bin/sh: /c/Ruby22-x64/bin/ruby: No such file or directory me confunde. Isso acontece em todos os três shells, Cygwin , GIT Bash , bem como CMD . No Bash do GIT , posso resolver o caminho /c/Ruby22-x64/bin/ruby manualmente. Existe e funciona. Também which ruby aponta para a direita ruby também.
