Error to install Nokogiri on OSX 10.9 Maverick?

Question

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

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.

The error is:

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.

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

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

sudo ln -s /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2 /usr/bin/gcc-4.2

Solution 2

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

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

Update

For those using Yosemite the following command will work:

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.sdk folder (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:

Update

For those using El Capitan the following command will work:

gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2 --use-system-libraries

Update

For those using Sierra the following command will work:

gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/libxml2 --use-system-libraries

Solution 3

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

Solution 4

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

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

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

gem install nokogiri

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

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:

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

Solution 5

This is what worked for me on OSX Mavericks:

sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install nokogiri -v '1.6.1' --verbose --no-ri --no-rdoc

[moander]

Try opening xcode and accept the EULA/license.

[David Portabella]

this didn't solve the issue for me, i still have the same error message :(

[David Portabella]

I completely uninstalled rvm and ruby (from brew), installed again, and it worked.

[trojanfoe]

Does it not compile using clang?

[trojanfoe]

How did you compile apple-gcc42 then? It must be easier to use the "default" compiler than to install a new (old) one?

[squiter]

So, I just run brew install apple-gcc42.. and just works. That command don't work for you?

[Quickredfox]

I ran xcode-select --install before the brew install and all works now.

[darkmoves]

I had to be very meticulous with the filepaths. It took me multiple tries to correctly construct the commands.

[squiter]

I don't have a paid account and I was installed the command-line tools. I installed using terminal, but a friend of mine installed using that download page, and he doesn't have a paid account too.

[shinesecret]

I Agree with you. Same thing happened with me till 24th Nov, 2013. However if you go to that page now and try to access it, it will give you this error. Weird thing is you login with your credentials but it will keep you login as guest. This is the message I get on page with my account: Apple Developer Program Big Warning We are unable to process your request.

Here's a link to another solution to the issue of an incorrect libxml version.

[Lucy Bain]

@BrunnoDosSantos where did you find the log? I checked my gems/nokogiri-1.6.1/ext/nokogiri/gem_make.out but it just had the same error message as in your question.

[squiter]

@LucyBain I realy don't remember.... but I think that log file was in same directory as gem_meake.out...

[Tim Stephenson]

When I ran brew install apple-gcc42 I gat a warning that it was already installed. Running brew uninstall apple-gcc42 and then installing it did the trick for me.

[Pop-A-Stash]

Not for me: "libxml2 is missing. please visit nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies." Still getting same error.

[Richard]

It helped me, although I do echo the sentiment of posting the answer here, rather than in a link :)

[Tizón]

Thank you, works for me! PS: very good jasdeep.ca/2013/10/installing-nokogiri-fails-os-x-mavericks

[superluminary]

Doh, yes, I had neglected to install the XCode command line tools on my clean Mavericks install.

[sparrow]

Perfect. Exactly what I needed. +1

[jmg]

Had to add --use-system-libraries. Than it worked on a brand new mavericks installation with Xcode 5.1.1 and brew.

[Volte]

would gem install nokogiri -- --use-system-libraries help?

[Maverick]

Had to add the --use-system-libraries to get this to work: gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Develop‌​er/Platforms/MacOSX.‌​platform/Developer/S‌​DKs/MacOSX10.9.sdk/u‌​sr/include/libxml2 --use-system-libraries

[Tim]

Cool. Now that you are using rvm on mavericks try opening vim. SEGV error? Lovely.

[Brian Hempel]

With bundler, I used bundle config build.nokogiri --with-iconv-dir=/Applications/Xcode.app/Contents/Developer/‌​Platforms/MacOSX.pla‌​tform/Developer/SDKs‌​/MacOSX10.9.sdk/usr

[Ben]

i had a similar issue (an unlinked libiconv). I unlinked libiconv, and reinstalled. brew install libiconv, then gem install nokogirl.

[Rogerio Chaves]

after googling it for hours, that was the only solution that worked for me, thanks! :D

[KonstantinK]

amazingly this is the only thing in this entire tread that helped me too. thanks!

[Tod Birdsall]

This worked for me: gem install nokogiri -- --use-system-libraries

[PJP]

The problem with this is, using sudo with RVM or rbenv will cause problems as root doesn't know where the sandboxed Rubies live. This is covered in the RVM installation page. The OP is using RVM, and using sudo would cause Nokogiri to install into Apple's Ruby, not the user's. So, don't do this unless you are SURE you want to install into Apple's Ruby if you're on Mac OS, or into the system Ruby if you're on another *nix.

[PJP]

Using sudo will cause Nokogiri to be installed in the only Ruby known by root, which is highly likely to be Apple's installed Ruby unless using Homebrew. Because the OP was using RVM, that means Nokogiri wouldn't be seen by a RVM managed Ruby, and would only compound the problem. Using sudo might have worked in this case, but it should not be tried with a RVM or rbenv managed Ruby. RVM specifically says not to do it in the installation documentation.

This worked for me, i tried about 50 SO threads and this was the only one that worked... osx 10.10.3

[Amax]

you're such a lifesaver!

[Erik Villegas]

This is the only one that would work for me, on 10.10.3: sudo gem install nokogiri -- --with-iconv-lib=/Applications/Xcode.app/Contents/Developer/‌​Platforms/MacOSX.pla‌​tform/Developer/SDKs‌​/MacOSX10.10.sdk/usr‌​/lib --with-iconv-include=/Applications/Xcode.app/Contents/Develo‌​per/Platforms/MacOSX‌​.platform/Developer/‌​SDKs/MacOSX10.10.sdk‌​/usr/include --with-xml2-include=/Applications/Xcode.app/Contents/Develop‌​er/Platforms/MacOSX.‌​platform/Developer/S‌​DKs/MacOSX10.10.sdk/‌​usr/include/libxml2 --use-system-libraries

[MattL]

Worked for me on Yosemite too. None of the above answers did.

[Durul Dalkanat]

you should use this command . open terminal. and Write this command. export NOKOGIRI_USE_SYSTEM_LIBRARIES=true

[Arian Faurtosh]

This post being updated for El Capitan makes me happy.

[Philipp]

You may want to update your answer with the more generic command that should work across all OS X versions and Xcode install paths: gem install nokogiri -- --with-xml2-include=`xcrun --show-sdk-path`/usr/include/libxml2 --use-system-libraries

[Dex]

The command for El Capitan worked for me as well to install -v '1.6.6.2'. Thank you!

[Onikoroshi]

I couldn't remove the gemset because the folders weren't empty, but reinstalling the gemset (even though there were errors) did! This is the only thing that worked for me!
