I am trying to install and use the Sablon ruby gem. I have installed xcode command line developer tools. However, I continue to get the following error:
ERROR: Error installing sablon:
ERROR: Failed to build gem native extension.

Any ideas as to what might be going on here?
try
gem install sablon -- --use-system-libraries=true
if it doesn't work may i ask how you installed xcode command line tools?

I found this "Zlib missing" continously when installing gems for Rails on Ruby, please let me know a solution :

zlib is missing; necessary for building libxml2
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.
I also re-installed OSX 10.14 SDK header but didn't work.
It turned out that I have to manually download zlib from its site and then install it myself to make it work.
Extract the package then install as instruction :
./Configure
make
make install
I uninstall version 0.18.1 and now I cannot install any of the versions.
I would like to install 0.18.2
I am running this command:
gem install pg -v '0.18.2'

Don't know how to fix the installation?
I used a wrong path, the correct command in my case is:
gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.4/bin/pg_config
I used 9.3 instead of 9.4
Can seem to get around this.

Any ideas?
try this before
sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2
apt-get install ruby{version}-dev
bundle install ffi
it worked for me
I had to set the gcc to 4.2 and it worked. I also changed the ffi version to 1.0.9 in Gemfile.lock.
export PATH=/opt/gcc-4.2.0/bin/:$PATH
Hi that's related with the GCC compiler i updated mine and also did the trick that Harpreet mentioned (ffi version downgrade) BUT it's not necessary ffi-1.9.3 worked just fine as well :D
in the Gemfile.lock
ffi (1.9.3)
ffi (1.9.3-x86-mingw32)

click here github repo with the .pkg installer for all OS (not only MacOSX)
As the title says, it doesn't seem to be failing because libxml2 or libxslt is missing. I'm not really sure what to make of the error. (Get it? Because the issue is during make? hehe...)
Anywho, here's the output I'm getting. Any ideas would be appreciated:

For context, I upgraded from Ubuntu 12.04 to 12.10 last night. I had previously built the Nokogiri native extension on this box, though I do not know if it was the same version or not.
I also checked that I have all packages specified in the second post on "error installing nokogiri 1.5.0 with rails 3.1.0 and ubuntu"
to no avail.
Took me some time to figure out how to append the cflags. Here is my command for nokogiri 1.4.7:
sudo gem install nokogiri -v '1.4.7' -- --with-cflags=\"-Wformat-nonliteral -Wno-format-security\"
If you're trying to install Nokogiri < 1.5.4, you'll have problems on hardened Debian systems like Ubuntu 12.
Details on the underlying issue are here: https://github.com/sparklemotion/nokogiri/issues/680
You should be able to upgrade to 1.5.4 or later and install without this problem.
Alternatively, you should be able to set the CFLAGS environment variable at gem-install time to include the string:
-Wno-error=format-security
or
-Wformat-nonliteral -Wno-format-security
Good luck!
Have you tried installing the following depencies for nokogiri??
# nokogiri requirements
sudo apt-get install libxslt-dev libxml2-dev
sudo gem install nokogiri
This may be happening due to this bug > https://leap.se/code/issues/7231
Run below before running the command:
sudo apt-get install zlib1g-dev

Any help would be awesome! Thanks.
Looks like you installed ImageMagick using a binary distro or something else which didn't include the headers. From your /Users directory you're probably using OSX. Assuming so, install ImageMagick using either Macports or Homebrew.
