I tried to install with bundle but it gave an error. I do have zlib installed.

Fetching nokogiri 1.7.0.1


Your user account isn't allowed to install to the system RubyGems.
  You can cancel this installation and run:

      bundle install --path vendor/bundle

  to install the gems into ./vendor/bundle/, or you can enter your password
  and install the bundled gems to RubyGems using sudo.

    for Ubuntu run: `sudo apt-get install zlib1g-dev` then reinstall `nokogiri` – Cyzanfar Nov 02 '17 at 00:17

    That worked. I installed `zlib1g-dev` and it worked. Oh, I thought that was an `l`. The font on StackOverflow is different than the terminal. I don't know why there are so many `zlib` packages. – Chloe Nov 02 '17 at 00:21

    Happy that helped! installing `nokogiri` worked after you installed `zlib`? – Cyzanfar Nov 02 '17 at 00:23

It looks like your error is coming from zlib:

zlib is missing; necessary for building libxml2

From this discussion it seems like installing the package might solve the issue:

for Ubuntu

sudo apt-get install zlib1g-dev

and then just try installing nokogiri:

gem install nokogiri -v '1.7.0.1'

Although the question is about Ubuntu, I ran into the error on MacOS and this is what worked for me:

For Mac OS Monterey

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

The problem was with the libxml:

libxml2 is missing. Please check the mkmf.log to check how it is failing.
