nokogiri gem installation error

Question

I know there are a lot of questions about this gem but no answer has worked for me.

When I run in SSH gem install nokogiri I get this error:

<         


        

Answer 1

Just Like wongzigii says the install command works with those flags with macOS Sierra

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 2

I ran into this same problem, because of an unlisted build dependency. When I found the tmp directory in question:

find ~/.rbenv/ -name patch.log

It said:

sh: patch: command not found

Fixed that with a simple:

sudo yum install -y patch

Answer 3

Am using macOS Sierra.

Went to nokogiri documentation and followed this:

ON MAC OSX

Installation should Just Work™ using Nokogiri’s vendored libxml2 and libxslt.

First, make sure you have the latest version of RubyGems and xcode commandline tools:

1 gem update --system

2 xcode-select --install

Then install nokogiri:

1 gem install nokogiri

Answer 4

Nothing in current answers worked for me (I use Ubuntu 16.04, not Mac).

However, by following the instructions in Nokogiri site and this part did the trick:

# See http://www.nokogiri.org/tutorials/installing_nokogiri.html#ubuntu___debian
sudo apt-get install build-essential patch
sudo apt-get install ruby-dev zlib1g-dev liblzma-dev

Note I've been using Nokogiri since 2009 and I've always had trouble installing it. Any further comment would probably not comply with SO T&Cs :)

Answer 5

step 1:

brew install libxml2

Step 2:

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

Step 3: then try

bundle install
