IRubyをインストールする(3)

どみとりさんに、 https://t.co/RkXFKqIDsQ を使えばうまくいくとおもうと教えてもらったので、インストールしてみた。過程を全部記録してないのだけど、最終的に以下のようなWarningが出る状態になった。下記は、ブラウザのウィンドウが新しくできるので、そこでファイルを選択した状態。gemに詳しくないのでよくわからない。Gemfileって個々のソフトウェアのディレクトリにあるやつかと思ってたが、your Gemfileとは、、、?

bundlerがどうこういわれているので、いちおう調べてみたが、FreeBSDのpackageとして1.10.6が入っている様子。slopは4.2.0, pryは0.10.3。

(追記)slopが新しいとエラーがでるっぽかったので3.6.0を入れて4.2.0は消した。そしたらエラー内容が変わりました。WARNはWARNなんだから無視していいのかな。となると、Bad address (src/fq.cpp:91)というのがヒントなのかな。

(追記その2)
どみとりさんに、libzmqのライブラリバージョンが違うのが原因でないか、3を使うとよい、と教えてもらったので、そのようにしたら動きました！

ノートであまりちゃんと記録をとらずにじたばたしたので、こんどはデスクトップマシンでインストール方法をちゃんとメモしてみたいですね。
