jekyll安裝rubyracer/execjs gem的問題

Question

試圖安裝gem rubyracer和gem execjs，原因我不記得了。

可能是因爲我試圖部署一個在服務器上顯示主要問題的jekyll站點。

因此，試圖運行jekyll --server

得到這個錯誤：

所以，因此的rubyracer和execjs

安裝嘗試這是我所得到的，當我嘗試安裝它們（消息對於兩者是相同的）：

/usr/local/rvm/rubies/ruby-2.1.2/bin/gem:8:in `require': no such file to load -- rubygems (LoadError) 
from /usr/local/rvm/rubies/ruby-2.1.2/bin/gem:8 

環境是linux服務器。不是我的筆記本。

jekyll --server已棄用，您可以使用jekyll serve。

我想你的RVM出了問題。嘗試使用rvm implode將其刪除並重新安裝。
