gem install nokogiri -v '1.6.8.1'が失敗する

新しいRailsアプリを作成し、nokogiriで問題が発生しました。gem install nokogiri -v '1.6.8.1'これは、以下の出力で失敗します。 Gemfile.lockを削除し、問題のない別のアプリからGemfileを使用してみました—bundle installはまだ失敗します。元の障害はbundle installこれは、他のアプリで引き続き機能します。

コンソールから：

IMPORTANT NOTICE:

Building Nokogiri with a packaged version of libxml2-2.9.4.

Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:

    gem install nokogiri -- --use-system-libraries
        [--with-xml2-config=/path/to/xml2-config]
        [--with-xslt-config=/path/to/xslt-config]

If you are using Bundler, tell it to use the option:

    bundle config build.nokogiri --use-system-libraries
    bundle install

Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

@the_basterdの推奨を試しました。それはうまくいきませんでしたが、リファレンスは良かったです。the_basterdに感謝します。その参照から働いたのは：

brew install libxml2

bundle config build.nokogiri --use-system-libraries --with-xml2-include=/usr/local/opt/libxml2/include/libxml2

参照： https://github.com/sparklemotion/nokogiri/issues/148

そのrefのその後の投稿は、私が上に投稿したものは「ノコギリによって強く推奨される」と述べた。

bundle install --path vendor/bundleを使用してGoogleドライブ同期フォルダー内にあるプロジェクトに直接インストールしているときに、nokogiri-1.6.8.1でこの問題に遭遇しました。ハングアップはlibxml2に関連しているように見えました。

@Gregと@the_basterdが参照するGitHubの問題を読んでいると、 Box同期フォルダーへのインストールで問題が発生した に気付きました。プロジェクトフォルダーを別の場所に移動できました。

同期フォルダーにインストールする際の根本的な問題が何であるかはわかりませんが、何か考えがあったかどうかを知りたいと思います。

これをDropboxでテストしたことはありませんが、おそらくそれも問題を引き起こすでしょう。
