Error while installing Nokogiri (1.6.7) on El Capi

问题:

One of my developers have updated Nokogiri, and when pulling the updated Gemfile my bundle install fails.

An error occurred while installing nokogiri (1.6.7), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.7'` succeeds before bundling.

As suggested in "Failing to install Nokogiri gem" I have unsuccessfully tried to run:

bundle config build.nokogiri --use-system-libraries
bundle install

As suggested in "Failing to install Nokogiri gem" I also tried:

gem install nokogiri -- --use-system-libraries

and:

gem install nokogiri -v 1.6.5 -- --use-system-libraries

My OS version is El Capitan 10.11.2, and I have checked that the Xcode licence agreement has been accepted.

Any ideas how to get the Nokogiri installation to succeed?

回答1:

You should install xcode-select packages first, then try installing nokogiri again. Try these commands,

xcode-select --install

then try

gem install nokogiri

with whatever Nokogiri version you want.

Nokogiri depends on multiple libraries like libxslt, libxml and zlib. Dev versions (including source) of these should be installed before installing Nokogiri in any Linux distribution. For OS X, the above command should work I guess.

The actual solution is in the comments below.

回答2:

Try this :

gem install nokogiri -- --use-system-libraries --with-xml2-include=/usr/include/libxml2 --with-xml2-lib=/usr/lib/

And then run

bundle update

I hope this could help you :)

回答3:

I you're using homebrew to maintain libraries like libml on your mac, the following command on your mac might help:

gem install nokogiri -v '1.6.8' -- --use-system-libraries --with-xml2-include=/usr/local/Cellar/libxml2/2.9.2/include/libxml2  --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.2/lib/

just ensure that the path for libxml is same as mine unless brew changes with the next version. You can check this by running the below command:

brew info libxml2

回答4:

Add gem "nokogiri", ">= 1.6.7.rc3" in your Gemfile

and then run

bundle install

回答5:

try to:

apt-get install ruby-nokogiri
bundle install

回答6:

Updating Xcode and Command Line Tools fixed all the errors for me. After that I could install Nokogiri with gem install nokogiri and after that gem install rails worked fine.

回答7:

The following steps worked for me

ruby -v
ruby 2.0.0p247 (2013-06-27 revision 41674) [universal.x86_64-darwin13]

Run the following to install RVM and the latest stable version of Ruby:
\curl -L https://get.rvm.io | bash -s stable --ruby

Install the Ruby interpreter:

rvm install 2.1.0 --autolibs=enable

After that's finished installing, run:

source /Users/{your_user_name}/.rvm/scripts/rvm
Run:

ruby -v
ruby 2.1.0p76 (2014-02-24 revision 45161) [x86_64-darwin13.0]

Thank you for posting this! I finally got nokogirl to run with bundle install correctly for my app after running the following:

bundle config build.nokogiri --use-system-libraries
