为什么不安装nokogiri？

Question

我有一个时间在Ubuntu 12.04上安装Nokogiri的魔鬼.我用rbenv.

    $ gem install nokogiri -v '1.6.1'
    ERROR:  While executing gem ... (Errno::EACCES)

    $ sudo gem install nokogiri -v '1.6.1'
    ERROR:  Error installing nokogiri:

好像我需要某种方式来sudo ruby -v给我2.0.0.我错过了什么？

sudo当你gem install使用rbenv 时,你不应该需要.不幸的是,对于新安装的.rbenv目录,所有权通常是不正确的.

首先执行此操作以正确设置权限:

sudo chown -R $USER "$HOME/.rbenv"

然后继续,再次运行安装:

gem install nokogiri -v '1.6.1'

它应该没有sudo.
