ruby 在 OSX 10.9 Maverick 上安装 Nokogiri 时出错？

Error to install Nokogiri on OSX 10.9 Maverick?

提问by squiter

I upgraded my OSX (Lion) to Mavericks and I can't install Nokogiri for my projects.

我将 OSX (Lion) 升级到 Mavericks，但无法为我的项目安装 Nokogiri。

I already install XCode 5.0.1, Command Line Tools (using xcode-select --install), and already installed libxml2 from Homebrew and I am still having problems.

我已经安装了 XCode 5.0.1、命令行工具（使用xcode-select --install），并且已经从 Homebrew 安装了 libxml2，但我仍然遇到问题。

The error is:

错误是：

An error occured while installing nokogiri (1.5.9), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.5.9'` succeeds before bundling.

I installed libxml2, libxslt and libiconv from Homebrew, and set the params to install Nokogiri, but don't work too.

我从 Homebrew 安装了 libxml2、libxslt 和 libiconv，并设置了参数来安装 Nokogiri，但也不起作用。

I can't find what's wrong in my enviroment, can you help me?

我找不到我的环境有什么问题，你能帮我吗？

To solve this problem I intalled apple-gcc42 using homebrew brew install apple-gcc42and created a symlink to my /usr/bin :

You can also install Nokogiri on Mac OS X 10.9 Maverickswith full XCode Install using:

您还可以使用完整的 XCode 安装在 Mac OS X 10.9 Mavericks上安装 Nokogiri ：

gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/libxml2

gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/libxml2 --use-system-libraries

or, it might actually be in your MacOSX10.11.sdkfolder (mine was as of 18-Sep-2015) anyways, so even if you are not yet fully up to El Capitan, I had recently updated XCode and you may need to use the El Capitan SDK path, which follows next:

After navigating the animated GIFs here, all that I had to do was simply xcode-select --installand the gem install nokogiriworked fine.

在此处浏览动画 GIF 后，我所要做的就是简单xcode-select --install并且gem install nokogiri工作正常。

If you're running Xcode 5.1, the command line tools don't work for nokogiri 1.6.1. You'll need to download the Late october 2013 tools from Apple. Once you do that run

如果您运行的是 Xcode 5.1，则命令行工具不适用于 nokogiri 1.6.1。您需要从Apple下载 2013 年 10 月下旬的工具。一旦你这样做了

sudo xcode-select -s /Library/Developer/CommandLineTools/

to set up your machine to use the Xcode 5.0.X command line tools, then run

将您的机器设置为使用 Xcode 5.0.X 命令行工具，然后运行

gem install nokogiri

If you want to reset your command line tools to the Xcode.app version afterward run

如果您想在之后将命令行工具重置为 Xcode.app 版本，请运行

sudo xcode-select -r

Or, another thing you can do is add the flag to ignore unknown command line arguments. Then the install looks like this:

或者，您可以做的另一件事是添加标志以忽略未知的命令行参数。然后安装看起来像这样：

sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install nokogiri

This is what worked for me on OSX Mavericks:

这就是在 OSX Mavericks 上对我有用的方法：

I'm on OSX Mavericks and my problem turned out to be a bad install of Ruby.

我在 OSX Mavericks 上，结果证明我的问题是 Ruby 安装不当。

So, I reinstalled ruby with rvm :

所以，我用 rvm 重新安装了 ruby​​ ：

rvm remove ruby 2.0.0p451
rvm remove ruby-2.0.0-p451 && rvm install ruby-2.0.0-p451

I was then able to

我当时能够

gem install nokogiri --no-ri --no-rdoc

Problem solved.

问题解决了。

I like to stick with system-provided stuff typically. This worked for me:

我喜欢坚持使用系统提供的东西。这对我有用：

I ran into this problem immediately after installing the Mavericks 10.9.5 update and the 10.9 Developer tools update from Apple. I ran xcode-select --install, but that did not fix the problem. Then I opened XCode, accepted the eula, and quit XCode. That fixed the problem.

在安装了小牛队 10.9.5 更新和 Apple 的 10.9 开发者工具更新后，我立即遇到了这个问题。我跑了xcode-select --install，但这并没有解决问题。然后我打开了 XCode，接受了 eula，然后退出了 XCode。这解决了问题。

This is the same as @thomas_witt's post but works on Mac OS X Sierra:

I had this problem today, on Maverick, this is how I ended up solving the issue:

我今天在 Maverick 上遇到了这个问题，这就是我最终解决问题的方式：

brew update
brew install libiconv
brew link libiconv

Make sure that you know the version of libiconv in Cellar mine below was 1.14, then install as below:

确保您知道下面 Cellar 我的 libiconv 版本是 1.14，然后安装如下：

gem install nokogiri -- --with-iconv-dir=/usr/local/Cellar/libiconv/1.14

If you require a particular version of nokogiri e.g -v '1.6.2.1' then install as:

如果您需要特定版本的 nokogiri 例如 -v '1.6.2.1' 然后安装为：

gem install nokogiri -v '1.6.2.1' -- --with-iconv-dir=/usr/local/Cellar/libiconv/1.14

Nokogiri was installed successfully!

Nokogiri 安装成功！
