An error occured while installing nokogiri (1.5.0), and Bundler cannot continue. 
Make sure that `gem install nokogiri -v '1.5.0'` succeeds before bundling. 

您可以跳过这一部分。错误信息几乎是自我解释，但网站需要更多的单词来解释代码。

有什么想法？

Answer 1

您需要在机器上安装所有必需的库。当你安装RVM时，它应该已经为你列出了这个。在rvm的当前版本上，您可以运行rvm requirements以查看确切的列表。现在，该名单是：

sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion

Answer 2

您需要安装libxml2。

在Mac OS，采用自制，这将是：

brew install libxml2 

见http://nokogiri.org/tutorials/installing_nokogiri.html。

Answer 3

你缺少一些软件包。尝试运行这个（仅限Linux）：

$ sudo apt-get install libxslt-dev libxml2-dev 

Answer 4

只是这样做：

sudo apt-get install libxslt-dev libxml2-dev libxml2 

然后在终端（Linux版）键入此/ CMD（窗口）：

export NOKOGIRI_USE_SYSTEM_LIBRARIES=true 

Answer 5

试试这个如果别人不工作， 它真的对我有用。 Devtools for CentOS

Answer 6

当我用这个代码，我得到了另一个错误：

ERROR: Error installing disposable: 
    invalid gem: package is corrupt, exception while verifying: undefined method `size' for nil:NilClass (NoMethodError) in /home/admin/.rvm/gems/ruby-2.1.3@lol/cache/nokogiri-1.6.4.1.gem 

我尝试了许多不同的解决方案，而是帮助MED：

$ rm /home/admin/.rvm/gems/ruby-2.1.3@lol/cache/nokogiri-1.6.4.1.gem 
$ gem update 
$ gem install nokogiri 

其他命令，可以帮助：

sudo apt-get install synaptic 
sudo apt-get update 
sudo apt-get install qt4-dev-tools libqt4-dev libqt4-core libqt4-gui 
sudo apt-get install build-essential 
sudo apt-get install "^libxcb.*" libx11-xcb-dev libglu1-mesa-dev libxrender-dev 

Answer 7

它看起来像一个宝石依赖性错误。

您需要运行bundle update命令。这既解决了依赖关系：

bundle update
