Nokogiri 'Failed to build gem native extension' when I run bundle install - ruby-on-rails

Question

I'm running bundle install and I'm getting this error:
Building nokogiri using system libraries.
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Gem files will remain installed in /Users/myuser/projectpath/vendor/bundle/ruby/2.0.0/gems/nokogiri-1.6.2.rc2 for inspection.
Results logged to /Users/myuser/projectpath/vendor/bundle/ruby/2.0.0/extensions/universal-darwin-13/2.0.0/nokogiri-1.6.2.rc2/gem_make.out
An error occurred while installing nokogiri (1.6.2.rc2), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.2.rc2'` succeeds before bundling.
Any ideas what could this be?
EDIT:
I also have installed nokogiri following the instructions in the tutorial, and the weird thing is that the gem was successfully installed. When I run gem list, I have nokogiri (1.6.2.1), but when running bundle install it displays the error.

Answer 1

Previous advises didn't help me, here is the solution for OS 10.9:
brew install libxml2
bundle config build.nokogiri "--use-system-libraries --with-xml2-include=/usr/local/opt/libxml2/include/libxml2"
bundle install

Answer 2

On Mavericks this workaround worked for me:
gem install nokogiri -- --use-system-libraries=true --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/libxml2
See: https://github.com/sparklemotion/nokogiri/issues/1099#issuecomment-43023208

Answer 3

On Amazon Linux, I had to install these two devel libraries, and then specify the include path for libxml2
$ yum install libxml2-devel libxslt-devel
$ gem install nokogiri -- --use-system-libraries=true --with-xml2-include=/usr/include/libxml2/

Answer 4

I also had some problems installing nokogiri, Than I installed following packages, It worked for me:
libxslt-dev
libxml2-dev
libruby1.8
libreadline-ruby1.8
libopenssl-ruby
libxml2
I am not sure, which one was exactly needed.

Answer 5

http://nokogiri.org/tutorials/installing_nokogiri.html. Refer to this link and install the dependencies required for nokogiri. Then run this
bundle config build.nokogiri --use-system-libraries
bundle install

Answer 6

On Yosemite 10.10.1, this step did not help (may be it works for others)
gem install nokogiri -- --use-system-libraries
Basically issue on my local was due to libxml2, so following workaround did the trick
bundle config build.nokogiri "--use-system-libraries --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/libxml2
bundle install

Answer 7

This worked for OS X El Capitan:
brew install libxml2 libxslt libiconv
After running the'brew install libxml2 libxslt libiconv ' You may find, that they are already installed. No worries, it never hurts to double check.
sudo gem install nokogiri -v '1.6.7' -- --use-system-libraries --with-xml2-include=/usr/include/libxml2 --with-xml2-lib=/usr/lib
bundle install
Change the version of nokogiri, if needed. e.g.
sudo gem install nokogiri -v '1.6.5' -- --use-system-libraries --with-xml2-include=/usr/include/libxml2 --with-xml2-lib=/usr/lib

Answer 8

For mac, the reason why it failed is that you didn't have latest Xcode Developer Tools. Nokogiri has already been packaged with libxml2. For the lack of latest Xcode Developer Tools, it can't build native extensions.
To update Xcode Developer Tools using:
xcode-select --install
And then:
gem install nokogiri
If you fix it by using
gem install nokogiri -- --use-system-libraries
may get a similar warning later:
WARNING: Nokogiri was built against LibXML version 2.9.3, but has dynamically loaded 2.9.0

Answer 9

The error states that your libxml2 system library is out of date. You need version 2.6.21 or later.
On my Debian/ubuntu system, nokogiri compiles for me, and I can see I have version 2.9.1
dpkg -l | grep libxml2-dev
ii libxml2-dev:amd64 2.9.1+dfsg1-3 amd64 Development files for the GNOME XML library
You have three options here.
Check if your OS package manager provides a newer version of libxml2
library
Download the latest libxml2 source code, compile and install
it
Manually specify an older version of nokogiri in your Gemfile
that works with older libxml2 library. The nokogiri changelog shows that you won't have this problem with nokogiri version 1.4.7 (although using an older
version can expose you to security issues)
For solution #3, you would put this in your gemfile:
gem 'nokogiri', '1.4.7'

On Yosemite 10.10 the following steps solved my issues completely:
sudo xcode-select -switch /Library/Developer/CommandLineTools
gem uninstall nokogiri libxml-ruby
gem install nokogiri

Answer 11

This thread on GitHub gave me the trick I needed get Nokogiri 1.6.2 to install:
My ~/.gitconfig had the setting autocrlf = input. When I remove this setting the nokogiri build succeeds.

Answer 12

On Yosemite 10.10 this workaround worked for me:
gem install nokogiri -- --use-system-libraries

Answer 13

For #CentOS I needed to do the following:
gem update --system
yum install libxml2-devel libxslt-devel ruby-devel
gem install nokogiri -- --use-system-libraries

Answer 14

This is an old thread, but I hit similar issues, and the solution in my case was quite different to those posted so far.
After some digging, I found this thread:
https://github.com/bundler/bundler/issues/2648#issuecomment-25124800
It talks about bundler using a different version of ruby to that used by gem.
From OP's paste, we can see bundler is using the Mac system copy of ruby:
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby
In my case I found that gem was coming from brew; which gem gave /usr/local/bin/gem which symlinks to /Cellar/ruby/2.3.3/bin/gem. My guess is that the OP's case was the same.
So, gem and bundler are not working off the same ruby installation, which explains why the OP sees this:
When I run gem list, I have nokogiri (1.6.2.1), but when running bundle install it displays the error.
In my case, I simply ran gem install bundler, which made bundler start using the brew version of ruby, and all problems disappeared.

On OSX 10.12 (Sierra) this worked for me:
gem install nokogiri -- --use-system-libraries=true --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/libxml2

Answer 16

I had this exact issue. I run a rails environment on a mac. After I upgraded from Yosemite to Sierra I believe thats when it started.
To fix the problem I just had to install xcode command line tools. I don't know if the Sierra upgrade removed them or what.
xcode-select --install
(this will install the xcode command line tools)
Also another symptom..things like git status won't work. After this i was able to do rails new appname and it was fine.

Answer 17

This can be fixed by installing libxml2:
brew install libxml2
bundle config build.nokogiri --use-system-libraries
bundle install

Answer 18

This is a problem with macOS, I tried everything above but nothing was working, So tried to install versions of libxml2 but everything in vain.
So use the below command to you will be in good shape then,
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
