在linux上安裝jekyll（fedora 20）

大家好，我用sudo gem install jekyll在我的Fedora 20上安裝了jekyll，並得到以下錯誤。我已經成功安裝了ruby和rubygems，在我看來，jekyll已經安裝好了。但是當我輸入jekyll serve時，頁面將不會被創建，並且我收到了類似的消息。我是fedora和ruby的新手，感謝您的幫助。在linux上安裝jekyll（fedora 20）

這是您的JSON解析器的問題。在您的堆棧跟蹤中查看cannot load such file -- json/pure？在運行Jekyll之前，您需要能夠成功運行gem install json或gem install json_pure。

謝謝，我試過你的解決方案，並安裝了一些更多所需的軟件工作。我還有一個問題要問，在這[post]（http://stackoverflow.com/questions/17033621/jekyll-wont-load-anymore-after-update?rq=1），人們說'sudo gem install jekyll'和'gem install jekyll'有不同的效果，並且輸入'gem list --all'有或沒有'sudo'，我有一個完全不同的寶石列表。這是爲什麼？ – user3805728

gem命令的'sudo'前綴爲您提供了關於rubygems安裝的全局透視。所以，如果您只運行'gem install'（沒有sudo或root權限），您將在您當前的主目錄下本地安裝特定的gem。 – sentenza

試圖通過它來安裝ruby-devel -

sudo yum install ruby-devel

和嘗試重新安裝jekyll -

sudo gem install jekyll

，並且確保你已經安裝nodejs，

sudo yum install nodejs
