Real quick, I am aware of a similar question. However, following the top rated answer does not work. I've already restarted my system and the terminal, but to no avail.
For some reason, Nokogiri does not recognize that I have libxslt1-dev installed, though I explicitly installed it, both with sudo apt-get install libxslt-dev and sudo apt-get install libxslt1-dev.
Here's the output; am I missing anything else?
$ gem install nokogiri -v '1.5.2'
Building native extensions. This could take a while...

Gem files will remain installed in ~/.rvm/gems/ruby-1.9.3-p125@rails3tutorial2ndEd/gems/nokogiri-1.5.2 for inspection.

EDIT: Upon closer inspection, I realize that the installer recognizes that I have libxslt1-dev installed, but it's failing one of the tests. Did I do something wrong with the installation?
EDIT 2: I am trying to install capybara with bundle install, and among its several dependencies, nokogiri and selenium-webdriver cannot find libxslt, and therefore I cannot use capybara.
EDIT 3: Here's the error message from the mkmf.log file; let me know if you need the rest of it.

回答1:
It seems like you have more than one copy of libxml2 (and possibly libxslt) installed, and they are confusing each other. Try searching for and removing any extra copies of these libraries (and their include files) from your system.
回答2:
Some ideas to try:
- try installing 1.5.0. If that fails at least you know it's your problem not nokogiri.
- try --with-xslt-dir --with-xslt-include and --with-xslt-lib options. Maybe you have an old libxslt earlier in your path
