OSX 10.10.2 installation problem (1.6.6.2) #1235

Closed ghost closed 9 years ago

ghost commented 9 years ago

I have tried everything I can think of and find to get this installed but no luck!

Command being run is: gem install nokogiri

Error:

Hi,

Thanks for reporting this issue. First, I'd like to make sure you've followed the instructions here:

http://www.nokogiri.org/tutorials/installing_nokogiri.html#mac_os_x

Can you confirm?

If you're still having issues, then please provide complete versions of all your log files. Thanks.

Yes, have followed it

************************************************************************
IMPORTANT NOTICE:

Building Nokogiri with a packaged version of libxml2-2.9.2
with the following patches applied:
        - 0001-Revert-Missing-initialization-for-the-catalog-module.patch
        - 0002-Fix-missing-entities-after-CVE-2014-3660-fix.patch

Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:

    gem install nokogiri -- --use-system-libraries
        [--with-xml2-config=/path/to/xml2-config]
        [--with-xslt-config=/path/to/xslt-config]

If you are using Bundler, tell it to use the option:

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

Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

Paging @zenspider -- I don't know what to make out of these architecture mismatches. Do you have any questions or advice for @oliver-whiteman around how his system is configured? This is mystifying.

ghost commented 9 years ago

OK, I have managed to get past that bit now by:

export ARCHFLAGS="-arch x86_64"

but now it's complaining about libxml2 missing:

checking for main() in -llzma... yes
checking for xmlParseDoc() in libxml/parser.h... no
checking for xmlParseDoc() in -lxml2... no
checking for xmlParseDoc() in -llibxml2... no
-----
libxml2 is missing.  Please locate mkmf.log to investigate how it is failing.

even though earlier in the logs it has:

Running patch with /Library/Ruby/Gems/2.0.0/gems/nokogiri-1.6.6.2/ports/patches/libxml2/0002-Fix-missing-entities-after-CVE-2014-3660-fix.patch...

Never fear! Some dumbass from Seattle is here!

zenspider commented 9 years ago

Well... I can't test against 10.10.2 as it isn't released yet. :(

zenspider commented 9 years ago

I've upgraded my rubygems to be the same version. Assuming we have the same version of clang (not reported, but mine is below), then this is probably/hopefully just a beta-release OS problem.

zenspider commented 9 years ago

Um... which is to say, everything installs fine on 10.10.1 w/ the same versions of everything.

Looks like it. I suppose that is equal parts annoying and good news

thiagomarzagao commented 9 years ago

Similar problem here (ld: symbol(s) not found for architecture i386; see full compile.log below), except that I'm on OS X 10.10.1 (not 10.10.2) and that export ARCHFLAGS="-arch x86_64" didn't change anything. I tried these tips, but no joy.

************************************************************************
IMPORTANT NOTICE:

Building Nokogiri with a packaged version of libxml2-2.9.2
with the following patches applied:
    - 0001-Revert-Missing-initialization-for-the-catalog-module.patch
    - 0002-Fix-missing-entities-after-CVE-2014-3660-fix.patch

Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:

    gem install nokogiri -- --use-system-libraries
        [--with-xml2-config=/path/to/xml2-config]
        [--with-xslt-config=/path/to/xslt-config]

If you are using Bundler, tell it to use the option:

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

Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

thiagomarzagao commented 9 years ago

Well, I gave up on trying to install the vendored xml2 and decided to use the system version instead. $ sudo gem install nokogiri -v '1.6.6.2' -- --use-system-libraries --with-xml2-include=/usr/include/libxml2 --with-xml2-lib=/usr/lib worked.

ghost commented 9 years ago

^^^^this

Works perfectly for me too. Thanks @thiagomarzagao

flavorjones commented 9 years ago

Looks like 10.10.2 dropped today. @zenspider is going to try to reproduce with the final (the above was with the beta).

zenspider commented 9 years ago

I just confirmed that nokogiri installed fine with stock ruby on 10.10.2 (final) for me.

If there are still problems for you, we need to compare notes and see what variables are different.

thiagomarzagao commented 9 years ago

I must have messed up something on my environment then (though I followed all the steps). Sorry about that. The system xml2 worked for me.

flavorjones commented 9 years ago

Great, thanks for letting us know! Closing.

rsanchezsaez commented 9 years ago

I'm experiencing the exact same problem on OS X 10.10.5 (14F27). By looking at the paths on the logs, this seem to affect users that have the libz.dylib, liblzma.dylib, lliblzma.dylib and libiconv.dylib libraries installed through Macports (they're in /opt/local/lib/).

Using the system libraries also fixed it for me, but I'm reporting the Macports bit in case it allows you to fix the root cause of the problem.

72apps commented 9 years ago

Thanks @rsanchezsaez. I'm using Macports and your analysis fixed the issue for me. I simply renamed /opt/local, installed the gem, then move /opt/local back.

equivalent commented 9 years ago

I know this is OSX question but I actually googled it when searching for Ubuntu solution

...so:

after upgrading to Rails 4.2.4 (which includes Nokogiri 1.6.6.2) on Ubuntu 14.04 (I'm using RVM) I needed to do this:

sudo apt-get install libgmp-dev

or 

sudo apt-get install libgmp3-dev
mwlang commented 7 years ago

For others coming into this...I encountered the same on OSX Sierra and Ruby 2.4.0.

I don't know where the libxml2 I already had installed came from, but brew warned me another version was already linked to opt. I choose to force homebrew's version and nokogiri installed thereafter as follows...

>> brew install libxml2
Warning: libxml2 is a keg-only and another version is linked to opt.
Use `brew install --force` if you want to install this version

>> brew install --force libxml2
Warning: libxml2-2.9.4_2 already installed, it's just not linked.

>> brew link --force libxml2
Linking /usr/local/Cellar/libxml2/2.9.4_2... 17 symlinks created

>> gem install nokogiri -v '1.7.0.1'  -- --use-system-libraries --with-xml2-include=/usr/include/libxml2 --with-xml2-lib=/usr/lib
Building native extensions with: '--use-system-libraries --with-xml2-include=/usr/include/libxml2 --with-xml2-lib=/usr/lib'
