我的操作系统是优胜美地10.10.2操作系统

以下是我到目前为止安装的内容，我使用

RMV

安装Ruby：

$ ruby -v

$ xcode-select -p

我使用以下方法安装了Rails，并不断出现上述错误：

$ gem install rails --no-ri --no-rdoc

$ gem install rails -v 4.2.0

$ gem install nokogiri -- --use-system-libraries --with-xml2-include=/opt/local/include/libxml2 --with-xml2-lib=/opt/local/lib --with-xslt-dir=/opt/local

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!

Warning: Some directories in /usr/local/share/man aren't writable.
This can happen if you "sudo make install" software that isn't managed
by Homebrew. If a brew tries to add locale information to one of these
directories, then the install will fail during the link step.
You should probably `chown` them:

    /usr/local/share/man/mann

Warning: A newer Command Line Tools release is available.
Update them from Software Update in the App Store.

Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:

  /opt/local/bin/libpng-config

Warning: Python is installed at /Library/Frameworks/Python.framework

Homebrew only supports building against the System-provided Python or a
brewed Python. In particular, Pythons installed to /Library can interfere
with other software installs.

Warning: You have MacPorts or Fink installed:
  /opt/local/bin/port

This can cause trouble. You don't have to uninstall them, but you may want to
temporarily move them out of the way, e.g.

  sudo mv /opt/local ~/macports

Warning: Unbrewed dylibs were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Unexpected dylibs:

    /usr/local/lib/libSFFileMonitor.32.dylib

Warning: Unbrewed .pc files were found in /usr/local/lib/pkgconfig.

Warning: You have a non-Homebrew 'pkg-config' in your PATH:
  /opt/local/bin/pkg-config

`./configure` may have problems finding brew-installed packages using
this other pkg-config.

Warning: Your Xcode (6.2) is outdated
Please update to Xcode 6.3.
Xcode can be updated from the App Store.

根据您的brew doctor输出：

sudo mv /opt/local ~/macports
mv  /Users/jdesilvio/anaconda  /Users/jdesilvio/anaconda.back

gem install nokogiri

然后有选择地放回macports（您可能不应该同时拥有macports和自制软件），并有选择地放回anaconda（不管是什么）。我的猜测是，anaconda目录中的libxml2安装正在弄乱nokogiri安装的libxml2头文件的路径。

您最好使用Ruby版本管理器来完成。这是一个坏主意，搞砸了随OSX提供的ruby版本，因为苹果依赖于某些版本来更新

安装RVM、Ruby和Rails

禁用多余的文档

echo "gem: --no-document" >> ~/.gemrc

安装带Ruby和导轨的RVM

\curl -L https://get.rvm.io | bash -s stable --auto-dotfiles --autolibs=enabled --rails

在当前终端会话中加载RVM

source ~/.rvm/scripts/rvm

如果还没有，请将其放在~/.profile文件中，以便在每次登录时加载

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

检查RVM是否作为功能加载

type rvm | head -1

检查版本

rvm -v
ruby -v
rails -v

您使用的是自制软件吗？您是否安装了XCode和XCode开发工具？是的，我使用的是自制软件，我已经安装了XCode和XCode开发工具。您可以粘贴cat/Users/jdesilvio/.rvm/gems/ruby-2.2的输出吗。0@global/extensions/x86_64-darwin-14/2.2.0-static/nokogiri-1.6.6.2/gem_make.out？

$brew安装libiconv

警告：libiconv-1.14已安装

和

gem安装nokogiri

导致相同的结果枪的儿子…是macports！移动了它，安装了nokogiri和rails！非常感谢…你知道为什么macports会导致这样吗？顺便说一句：anaconda是Python发行版，原因很可能是在编译本机nokogiri C代码时，它在macports下查找libxml2，没有找到它，结果失败了。echo$LD\u LIBRARY\u PATH和$PATH的输出是什么？

$echo$LD\u LIBRARY\u PATH

没有返回任何内容<代码>$echo$PATH/Users/jdesilvio/.rvm/gems/ruby-2.2.1/bin:/Users/jdesilvio/.rvm/gems/ruby-2.2。1@global/bin:/Users/jdesilvio/.rvm/rubies/ruby-2.2.1/bin:/opt/local/bin:/opt/local/bin:/opt/local/sbin:/usr/local/heroku/bin:/Users/jdesilvio/anaconda/bin:/usr/local/bin:/Library/Frameworks/Python.framework/Versions/3.4/bin:/usr/local/bin:/usr/bin:/usr/local/bin:/usr/bin:/sr/sbin:/sbin:/usr/local/git/bin:/Users/jdesilvio/.rvm/bin运行

\curl-L时，我想我一直在使用rvm安装https://get.rvm.io |bash-s stable--auto dotfiles--autolibs=enabled--rails

我收到了同样的错误不确定~/.profile文件在哪里，但是

[-s“$HOME/.rvm/scripts/rvm”]]&&source“$HOME/.rvm/scripts/rvm“

应在安装rails后添加？？是，请在安装后添加。根据shell设置，从

\curl-L中读取$PATH变量可能是~/.profile、.bashrc或.zshhttps://get.rvm.io |bash-s stable--auto dotfiles--autolibs=enabled--rails

install不起作用…我还应该更新.profile吗？除非在该目录中安装了程序。~/。rvm/脚本/rvm
