Jekyll升級問題

Question

我想將Jekyll升級到1.5.1以獲得一些最新功能，但我遇到了一些麻煩。

我目前的版本是1.2.1和which jekyll返回/usr/bin/jekyll。 Rubygems在2.2.2。我在OSX 10.9.2上。

當我只是運行gem update jekyll它告訴我沒有什麼可更新的。當我運行gem uninstall jekyll時，它不會返回任何內容，即使啓用-V也是如此。 which jekyll一直指向usr/bin/jekyll和gem install -v 1.5.1然後給我編譯錯誤，我猜是因爲仍然安裝了舊版的Jekyll。

以下是gem list輸出：

任何想法？

我能夠在這裏修復這個錯誤， Fast-stemmer installation problems

原來我不得不運行sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install jekyll才能正常工作。

不知道這一切做什麼。 :)
