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:
ERROR: Error installing mysql2:

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

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'm trying to install PostgreSQL's pg gem for Ruby.
I issued the following command:
gem install pg
I installed Ruby 1.9.2 using RVM.
The above command shows me the following error.
The error is :
Building native extensions. This could take a while...
ERROR: Error installing pg:

Somebody gave solution for Ubuntu users.
What about OpenSUSE Linux?
Thanks for advance.
For me this was the solution:
zypper in postgresql-server-devel
pg_config is part of postgresql-server-devel, if you install that
package then it should work on Tumbleweed at least.
Source: https://lists.opensuse.org/opensuse-factory/2019-03/msg00300.html
As per my search OpenSUSE linux has no package for client of Postgres, but as you have installed that it, that mean chances are the file pgsql.so is present in your system. How did you install it, I can see following which says it will install development libraries and client also
sudo zypper in postgresql postgresql-server postgresql-contrib
sudo zypper in postgresql-plperl postgresql-plpython postgresql-plctl
If this does not work then try to search in postgres installation path this file, locate file_name is easy to find files on different linux, but not sure it works in openSUSE it is part of mlocate package. If you find that file then symbol link it as per error, where error is searching this file.
If it is still not working, then you can use your Postgres directory in environment variable and try to install gem individually. To get postgres configuration use following command to see directories.
pg_config
Now try to install gem
PATH=$PATH:/Library/PostgreSQL/9.0/bin sudo gem install pg
On some system following command also resolve issue, so you can try it too
sudo gem install pg – --with-pg-config=/usr/local/pgsql/bin/pg_config
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 looked everywhere I can find but can't seem to find a solution to this.
I'm using Xcode 4.5.1 on Lion 10.8.2, and am trying to run bundle for a Rails project and it keeps jamming up on this. I'm using the Thin gem for Heroku.

For now I'm having to do without Thin. Does anyone have a solution?
Also check for a symlink:
$ sudo ln -s /usr/bin/g++ /usr/bin/g++-4.2
You have to install the Command Line Tools package from developer.apple.com.
Also I was having troubles with the MacOSX10.6.sdk because some headers were missing there, so I installed the MacOSX10.5.sdk and all worked fine.
I had the exact error, and creating a new symlink for the missing resource /usr/bin/g++-4.2 worked for me.
In my setup I pointed at the location in Cellar:
/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/g++-4.2
If none of the above work for you, I did
sudo ln -s /usr/bin/llvm-g++-4.2 /usr/bin/g++-4.2
and it worked like a charm. Running OS X 10.8.2.
You should have both:
Xcode command line tool: Detailed instructions for installation are in "How to install Xcode Command Line Tools".
Apple-gcc* compiler: I should mention that compiling with gcc48 and gcc49 fails. Therefore, installing apple-gcc42 (if you don't have) and choosing the compiler via MacPorts will solve the problem. You can see the installed gcc versions using:
port select --list gcc
You should see something like this where "mp-" stands for MacPorts own port:
Available versions for gcc:
apple-gcc42 (active)
current_saved
mp-gcc48
mp-gcc49
If you don't have "apple-gcc*" you may install it via:
port install apple-gcc42
after that chose the compiler:
port select --set gcc apple-gcc42
Now you may run:
gem install eventmachine
This should solve the problem of errors which arise during building gem native extensions on OSX.
I just upgraded from OS X Lion to OS X Mountain Lion.
My rails environment for the most part stayed in tact.
The only steps I had to do to get things back to a good state was:
- Install XCode 4.4
- Install XCode 4.4 Command Line Tools
- Install gcc-4.2
So all that went well.
Here's the issue, almost all my gems install properly when I run bundle install except for one of the most important ones I need - the postgresql gem 'pg'.
And it specifically fails for versions above 0.12.2.
I'm using ruby 1.9.3p125.
I can successfully grab the 0.12.2 pg gem, and versions below, but they give me segmentation faults (I'm guessing because of the version of ruby I'm using).
So this leads me to believe that it's specific to the pg gem, and not my overall environment seeing as other gems install fine.
I also tried re-installing Postgresql to ensure my postgres environment is ok and seems good on that front.
Has anybody been able to install the 'pg' gem version 0.13.0 or above (and more preferrably 0.14.X)?
Here is my stack trace:

Deefour's comment got it! It was the way I installed PostgreSQL.
I use the PostgreSQL one-click installer which I'm guessing doesn't set up the libpq up properly for Mountain Lion.
Homebrew on the otherhand will build it properly for the OS.
After installing postgres through homebrew
brew install postgresql
I was able to install my gem no problem.
Thanks everybody!
The issue is the location of pg_config. If you use the one-click installer, it is in /Library/PostgreSQL/9.2/bin/pg_config, so this will build your gem just fine:
env ARCHFLAGS="-arch x86_64" gem install pg -- --with-pg-config=/Library/PostgreSQL/9.2/bin/pg_config
I had the exact same issue; same stack trace as you've posted.
MRI 1.9.3-p286 / OS X 10.8.2 / Postgres 9.0.4 with homebrew.
I solved it by simply doing:
$ brew update
$ brew upgrade postgresql
$ bundle
Hope it works for someone else.
Reinstalling ruby fixed a similar issue I was having after upgrading to Mountain Lion
rvm reinstall 1.9.3
Note: also run the following as it seems the default version resets
rvm --default 1.9.3

Like Matt, Ranjan, and Peter Mellett all say, you have to get the right pg_config location, and Mountain Lion comes with a different location that doesn't seem to play well with rubygems, so if you find your old version like
