I tried installing the bluecloth gem by typing
gem install bluecloth
But when I do that I get the following error message:
checking for random()... *** 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.
Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib

What options am I supposed to provide?
I needed to have markdown installed before I tried to install the gem.
run
brew install markdown
then
gem install bluecloth
I had the same problem when trying to install bluecloth 2.0.11 under Ruby 2.2.3. Turns out that Ruby 2.2.3 was too new. Going back to Ruby 2.1.5 resolved the issue.
Check your .ruby-version.

I am using M1 Macbook Pro and wants to install therubyracer and libv8 for a rails webapp. But I am unable to do so because of the errors described below. There are several solutions available on the internet but none of them is working for me.
Operating System: macOS Big Sur v11.1.
It would be very helpful if someone can help me with this.

This works for me:
Ruby version: 2.6.1
OS version: macOS Big Sur 11.2
Install HomeBrew using Rosetta Termina
https://5balloons.info/correct-way-to-install-and-use-homebrew-on-m1-macs/
brew install v8#3.15
gem install libv8 -v '3.16.14.19' -- --with-system-v8
gem install therubyracer -- --with-v8-dir=/usr/local/opt/v8#3.15
I fixed this by installing V8 on Rosseta 2 as V8 not yet supported for ARM.
You can try this
gem install therubyracer -v '0.12.3' --
--with-v8-dir=/usr/local/opt/v8#3.15
Or install V8 on Rosseta 2.

It looks like you still need to install MySQL's development libraries. These are required for the gem to build successfully on your system.
[Edit] Seems the RoR Wiki is no longer available. But, Ubuntu has offered their own walkthrough which suggests:
sudo apt-get install mysql-server mysql-client
sudo apt-get install libmysql-ruby libmysqlclient-dev
sudo gem install mysql
See http://wiki.rubyonrails.org/database-support/mysql#installation for more detail.
Example: Ubuntu
sudo apt-get install mysql-server mysql-server-5.0 libmysqlclient15off \
libmysqlclient15-dev mysql-client-5.0 mysql-common
sudo apt-get install libmysql++-dev
sudo gem install mysql
I'll just leave this here:
I ran into a similar problem, then realized I couldn't install the mysql2 gem without having MySQL installed on my development machine (even though I'm only using the mysql2 gem to connect to a remote MySQL server).
::forehead slap::
brew install mysql
then, in my Gemfile:
gem 'mysql2', '~> 0.3.11'
followed by a quick
bundle install
Success!
If you are running Rails 3 you should use the mysql2 gem. You can install it with:
gem install mysql2
You will need to first install MySQL and any development headers. This will vary across different operating systems. On Ubuntu, you can run:
aptitude install mysql-server
aptitude install mysql-client
aptitude install mysql-common
aptitude install libmysql-ruby
aptitude install libmysqlclient-dev
If you are creating a new project, use:
rails new sample --database=mysql
cd sample
bundle install
For more details, check out the project repository.
I assume you are working with Rails.
In your Gemfile:
gem 'mysql2'
Then in your terminal:
bundle
In 2013, Using Ubuntu 12.04, this worked for me:
sudo apt-get install mysql-client libmysqlclient-dev
bundle install
When I run
$ gem install pg
I get the following

What does the "sh: : command not found" mean?
Is this the reason why the installation is failing?
Background:
I am using Cygwin
I used the one click installer of PostgreSQL
The pg_config.exe file is located at C/Program Files/PostgreSQL/9.0/bin/pg-config.exe
The libpq-fe.h file is located at C/Program Files/PostgreSQL/9.0/include/libpq-fe.h
You can't mix and match native Windows code and Cygwin code. If you want to link to libpq you'll need the cygwin build libpq and you'll need to make sure the version of pg_config found on the PATH is the cygwin one. The pg_config from the native Windows build will produce output the Cygwin tools cannot understand, and even if they could they wouldn't successfully link against the native library and run with it.
As I no longer use Cygwin I can't offer any advice on the current way to install libpq. Presumably there's a lib in Cygwin's package management that'll be called something like postgresql-client, libpq, etc.
Cygwin is a pretty low priority platform for PostgreSQL at this point. Given that Ruby+Rails and PostgreSQL both have native Windows versions, you're setting yourself up for a hard time here, and I'd advise you to use the native versions of both tools. You can still work within a unix-like shell environment using msys bash and can use MinGW's gcc to produce native Windows executables and libraries if MSVC++ isn't an option.
This worked for me:
sudo apt-get install postgresql
sudo apt-get install libpq-dev
Then
gem install pg
This is interesting. I had rdiscount working within one rvm gemset, but when I tried to add it to another, I would get ERROR: Failed to build gem native extension. So I tried removing it from the original gemset and re-installing it only to get the same error. I'm not sure what is going on. I'm trying to use it with Jekyll and Octopress builds. I'm on OS X 10.7.5.
Here's what happens:

Did anyone know what i can do to install rmagick correctly?
I'm going to take a guess that it's an upgrade and not pre-installed? I recently upgraded to Lion and had to do something like:
uninstall xcode 3 (there's a non-destructive version of the uninstall script in case you care)
install xcode 4 (free from the app store. big download).
i use macports. i had to uninstall and reinstall them all. you'll need to do the same for homebrew if you haven't already.
symlink or pass on command line the new gcc compiler (rmagick references gcc-4.2, but with xcode 4 it's called llvm-gcc-4.2. look up what that means if you're interested http://llvm.org/)
That pretty much sums up what I had to do. The clue was in the mkmf.log, so definitely look in there and update your question if my answer doesn't do it for you.
