jekyll安装rubyracer/execjs gem的问题

Question

试图安装gem rubyracer和gem execjs，原因我不记得了。

可能是因为我试图部署一个在服务器上显示主要问题的jekyll站点。

因此，试图运行jekyll --server

得到这个错误：

所以，因此的rubyracer和execjs

安装尝试这是我所得到的，当我尝试安装它们（消息对于两者是相同的）：

/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 

环境是linux服务器。不是我的笔记本。

jekyll --server已弃用，您可以使用jekyll serve。

我想你的RVM出了问题。尝试使用rvm implode将其删除并重新安装。
