わかりました、私はこれで私のテザーの終わりにいます。同様の質問がいくつかありますが、それらはすべて therubyracer 0.10 に言及しており、0.12 にアップグレードすることで問題を解決できると結論付けています。

私は同様の問題を抱えていますが、0.12.

類似の質問

「標準」（xcode？）gcc、およびhomebrewのapple-gcc42とgccの両方を使用すると問題が発生します。--with-system-v8と の両方を試しましたが--without-system-v8、サイコロはありません。

ここにいくつかのログがあります:

わかった。したがって、therubyracer 0.10 の問題を修正するには、brew で v8 をインストールしてから、システム v8 を使用するように ruby​​gems に指示することを推奨する人もいます。しばらく様子を見てみましょう！

OK、これでソートされました。

同じ問題を抱えている将来の人々のために、以前のOS Xのインストールに対してrubyをビルドすることに苦しんでいました.

問題のあるRubyをアンインストール/再インストールするだけでよいと思いますが、rvmを完全にnukingして最初からやり直すことで修正しました。

ここで問題がどのように解決されたかの詳細:

rubygemsシステムに間違ったバイナリをフェッチしている可能性があります。

診断：

  • gem env platformの出力を下の「カーネル バージョン」と比較します。 > About This Mac > System Report > Software
  • それらが一致しない場合 (例:Kernel Version: 14.4.0とx86_64-darwin-12)、RubyGems はシステム用のtherubyracerとの間違ったバージョンを取得しています。libv8

修理：

  • 短期：bundle update therubyracer --platform=x86_64-darwin-14

OSX Mountain Lion から OSX Mavericks にアップグレードしたときに、同じ問題が発生しました。ruby 1.8.7 のパッチレベルが重要らしい。

ruby-1.8.7-p354 から ruby​​-1.8.7-375 にアップグレードするとうまくいきました。

libv8 (3.16.14.3-x86_64-darwin-13) と therubyracer (0.12.0) の gem が問題なくインストールされました。

rbenv を使用すると仮定します。
