Failed to install pg 0.18.2 on iOS 10.10.5 - pg

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

How to FIX Zlib missing error on OSX 10.14?

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

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

ERROR: Failed to build gem native extension when installing Sablon gem

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:

if it doesn't work may i ask how you installed xcode command line tools?

Install gems on Windows with RailInstaller: "You must have zlib installed"

I'm on Windows, with Ruby 2.0 installed using RailsInstaller.
When I tried to install id3lib-ruby using gem install id3lib-ruby, I get the following:
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
ERROR: Error installing id3lib-ruby:

In mkmf.log, it includes the line:
c:/railsinstaller/devkit/mingw/bin/../lib/gcc/mingw32/4.5.2/../../../../mingw32/bin/ld.exe: cannot find -lz
collect2: ld returned 1 exit status
I have zlib1.dll in C:\RailsInstaller\Ruby2.0.0\bin, renaming the file to zlib.dll doesn't work. So, it looks like RubyInstaller already included the zlib library, but something's still causing the gem install to fail. Any ideas?
Couldn't work it out. "Fixed" by installing RailsInstaller 2.2.2 (Ruby 1.9.3) and taglib-ruby instead.

I am running Lubuntu 13.04. The depencies: pg and sequel are installed. Packages files postgresql and postgresql-server-dev-9.1 is also installed
Does anyone have a clue?
This bug was fixed in master of the gem with this patch. You should wait for new release or install head version of the gem.

I have sqlite3-ruby installed as well as the header files, but for some reason it fails when checking for sqlite3_open()

I am running Snow Leopard. I'm not sure about previous installations of sqlite3 but I did try this:
port search sqlite
And it returned the following (among others):
...
sqlite3 #3.6.17 (databases)
an embedded SQL database engine
To be honest I'm not sure what all this means. What would anyone suggest for getting do_sqlite3 installed for use in Rails 3 with DataMapper? (Also, running it without the 'env ARCHFLAGS="-arch x86_64"' gives the same errors.)
Ok, first question is why are you passing the ARCHFLAGS? That should not be necessary, if it also doesn't work without passing them, what is the output you get then?
Next question is what version of sqlite3 is it picking up? Do you have sqlite3 installed through Macports for example? Did you upgrade to Snow Leopard recently and still have an sqlite3 install from before upgrading?
