I am not able to install the latest version of mysql2 gem for my rails application. I have already tried out the options suggested in this answer. However the older version installed without any errors!
gem uninstall mysql2
gem install mysql2 -v 0.2.6
Following is the error that pops up whenever I try to install the latest version of mysql2 gem

I have 8.0.30 version of mysql and ruby v3.0.4 installed. I'm able to run mysql on my system and create databases but I cannot run this command:
gem install mysql2 -v '0.5.4' -- '--with-mysql-lib="C:\Program Files\MySQL\MySQL Server 8.0\lib" --withmysql-include="C:\Program Files\MySQL\MySQL Server 8.0\include"'
I getting following error:

mysql client is missing. Check your installation of MySQL or Connector/C, and try again.

*** extconf.rb failed ***
Do you have the client lib files (not just the server) installed locally?

I know this isn't a direct solution, but I'd strongly encourage having a look at developing under WSL2. Developing Ruby apps under native Windows often involves a lot more mucking about that just using the Linux subsystem.
I've looked at and tried just about everything on the topic here at Stackoverflow.com and still can't figure this out...

Anyone who has an idea, suggestion, tip, fix, etc... I'd be really grateful.
Thanks!
From the answer at this question, running the following worked for me
gem install mysql2 --source 'https://rubygems.org/' -- --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include
I ran into this same issue on Mojave, and none of the previous answers worked for me but this commands mentioned in this Github issue comment did
Step 1.
brew install openssl
Step 2.
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/
In my case I already had openssl installed so it was really the export command that solved the problem.
Make sure openssl is installed on Mac via Homebrew.
brew install openssl
Install mysql2 gem.
gem install mysql2 -v '0.5.2' -- --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include
If the bug is not fixed, this above solution is the last one
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
Another solution if the above does not work.
cd /usr/local/Cellar/openssl/1.0.2s/lib/
sudo cp libssl.1.0.0.dylib libcrypto.1.0.0.dylib /usr/local/lib
This worked for me on macOS Catalina:
Make sure you have openssl installed. If not:
brew install openssl
Then do the gem install:
gem install mysql2 -- --with-opt-dir="$(brew --prefix openssl)"
Try this:
which mysql
Then, use the output-result to install the gem using the existing mysql installation directory:
gem install mysql2 -- --with-mysql-dir=<mysql-installation-directory>
It away working for me after 2h crazy

What am I getting wrong? Is it an issue with my RVM?
With some basic updates, I was able to get it to work.
bundle update
and then
bundle
installs the gem.
Thanks to https://github.com/celluloid/nio4r/issues/46
Another approach would be to install a later version of ruby with RVM and do bundle again. Both works

I had the exact same problem (Mac 10.9.3) and followed the advice on https://github.com/larskanis/fxruby/issues/7 (actually reference a Debian installation)
This was basically to try sudo gem install fxruby -- --with-cppflags=-I./include
Worked for me
Hope it helps.

It looks like you either need to specify your postgres lib directory:
gem install pg -- --with-pg-dir=/path/to/pg_dir
or perhaps a 32bit vs.64 bit compatibility problem
ARCHFLAGS='-arch x86_64' gem install pg
"env ARCHFLAGS="-arch x86_64" gem install pg" worked for me when using Snow Leopard.
