Well, then tried to access the pdf version of my page. But it also showed me an error
Runtime Error ControllerName#show

Add wkhtmltopdf installation path in your pdfkit configuration file (config/initializers/pdfkit.rb) as below
PDFKit.configure do |config|
# Download compatible version of wkhtmltopdf from 'http://wkhtmltopdf.org/downloads.html'
# Install it in your system.
# Then run 'which wkhtmltopdf' in your terminal to identify the path and update it below
config.wkhtmltopdf = '/usr/local/bin/wkhtmltopdf'
end

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.

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/

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.

This is the documentation issue. Do this: gem update rdoc before gem installations. It should fix it. Or just ignore the documentation installation with --no-document key

C:/Ruby200/lib/ruby/gems/2.0.0/gems/mysql2-0.3.11-x86-mingw32/lib/mysql2/mysql2.rb:2:in `require': cannot load
such file -- mysql2/2.0/mysql2 (LoadError)
I use Ruby 2.0.0 from RubyInstaller on Windows XP box.
I figured out what is the problem but I don't know how to solve it. The problem is that there is no any 2.0/ directory in the mysql2-0.3.11-x86-mingw32 gem. This is the gem that rails installs as its dependency from Gemfile:
GEM
remote: https://rubygems.org/
specs:
... many gems here
mysql2 (0.3.11-x86-mingw32)
... many gems here
DEPENDENCIES
...
mysql2
...
This is what is in that mysql2.rb file:
# C:\Ruby200\lib\ruby\gems\2.0.0\gems\mysql2-0.3.11-x86-mingw32\lib\mysql2\mysql2.rb
RUBY_VERSION =~ /(\d+.\d+)/
require "mysql2/#{$1}/mysql2" # <<-- this is that #2 line that throws an error
It is obvious that it takes the current Ruby version number and uses it as the path segment to reach some mysql2 file. In fact it is mysql2.so file. As I use Ruby 2.0.0 the path segment is 2.0:
mysql2/2.0/mysql2
Ok, now lets see how that directory of mysql2-0.3.11-x86-mingw32 gem looks like:
dir: C:\Ruby200\lib\ruby\gems\2.0.0\gems\mysql2-0.3.11-x86-mingw32\lib\mysql2\
No any 2.0/ directory.
I know the issue about libmysql.dll. I have it in my C:\Ruby200\bin. It doesn't help.
I read this answer https://stackoverflow.com/a/5368767/1114926 from the creator of RubyInstaller. I tried but it didn't help. It works for Ruby 1.9.3 because there is 1.9/ directory. But it doesn't work for Ruby 2.0.0.
How to solve it?
UPD 1:
Thank you for your answer. I've tried. Unfortunately I have ERROR: Failed to build gem native extension. error:

It says:
You have to install development tools first.
But I have full DevKit installed, RubyInstaller installs it. Can't understand what else does it need.
I've already posted an issue to mysql2 GitHub page https://github.com/brianmario/mysql2/issues/364. No answers yet.
Had the absolutely same issue on Windows 7 x64 with Ruby 2.0.0 and DevKit 4.7.
The following steps helped me.
gem uninstall mysql2
Download last MySQL connector from http://cdn.mysql.com/Downloads/Connector-C/mysql-connector-c-noinstall-6.0.2-win32.zip
Extract it to C:\connector-6.0.2
gem install mysql2 --platform=ruby -- '--with-mysql-lib="C:\connector-6.0.2\lib" --with-mysql-include="C:\connector-6.0.2\include" --with-mysql-dir="C:\connector-6.0.2"'
Or even shorter:
gem install mysql2 --platform=ruby -- --with-opt-dir="C:\connector-6.0.2"
uninstall mysql2-0.3.11-x86-mingw32, gems compiled before Ruby200 won't work. You have to compile it yourself.
If you run gem uninstall mysql2 and there is a non compiled version listed then just uninstall mysql2-0.3.11-x86-mingw32 - the compiled version else...
Installation
gem install mysql2 --platform=ruby. that would work.
Follow this guide on installing devkit http://rubyonwindowsguides.github.com/book/ch02-04.html.
Then try again.
Exactly the same behavior when I try to install Redmine on windows XP
when I try to do the "rake generate_secret_token", I got "cannot load
such file -- mysql2/2.0/mysql2 (LoadError)"
and when I try to re build mysql2 using --platform=ruby, I got the
same message as you green.
for the moment, I am stucked there ... but if anybody has anything to allow me to move forward, it will be very welcome.
I will keep informed as well

I almost done the same what #odiszapc described. Uninstall old gem, download mysql-connector-c-noinstall, unzip, but finally I used this command to build native gem:
gem install mysql2 --platform=ruby -- --with-opt-dir=/c/connector-6.0.2
(If you use git-bash then you can use unix style directory syntax.)
Copy paste from that link: https://github.com/brianmario/mysql2/issues/359. It worked for me.
If after installing the gem, you get an error:
"The specified module could not be found.
C:/Devel/Ruby200/lib/ruby/gems/2.0.0/gems/mysql2-0.3.11/lib/mysql2/mysql2.so"
That can be fixed by copying libmysql.dll to Ruby's bin folder.
I recently upgraded to osx 10.8 (Mtn Lion) and now I am having problems with Imagemagick. I get the following error when I try to upload a file:

I uninstalled / reinstalled homebrew and imagemagick. I even added the rmagick gem (which I didn't need before) but still get the above error.
brew install imagemagick
Error: imagemagick-6.7.7-6 already installed
Here is brew doctor output:
brew doctor
Warning: Setting DYLD_LIBRARY_PATH can break dynamic linking.
You should probably unset it.
Warning: You have uncommitted modifications to Homebrew's core.
Unless you know what you are doing, you should run:
cd /usr/local && git reset --hard
Warning: /usr/bin occurs before /usr/local/bin
This means that system-provided programs will be used instead of those
provided by Homebrew. The following tools exist at both paths:
xml2-config
xmlcatalog
xmllint
xslt-config
xsltproc
Consider amending your PATH so that /usr/local/bin
occurs before /usr/bin in your PATH.
I even added the following to my config/environments/development.rb file
Paperclip.options[:command_path] = "/usr/local/bin"
I uninstalled Imagemagick again and reinstalled it. Now I get the following link errors.

Error: No such file or directory - /usr/local/Cellar/jpeg/8c
When I type brew link libtiff

So in summary the links are looking for older versions of jpeg (8c instead of 8d) and libtiff (3.9.5 instead of 4.0.2)
Any ideas on how to fix this?
I was able to finally fix it with 2 commands. Simple symbolic link, seems pretty hackish...
jpeg fix
cd /usr/local/Cellar/jpeg
ln -s 8d 8c
libtiff fix
/usr/local/Cellar/libtiff
ln -s 4.0.2 3.9.5
I just installed rvm and then rails 3.1rc5 with:
gem install rails --pre
But I got some errors after "Installing ri documentation" and the RDoc documentation:

The README file issues don't seem to be a big deal, but the 'lib' file not found sounds a bit scary.. why is it doing that? Some searching revealed others having this problem and fixing it with gem install rdoc and then re-running gem install rails --pre. But that still gives the same lib file missing errors for me.
Try using rvm gemset install rails --pre
I installed 3.1.0 on Windows (not rc8, but the final release), and got the "file 'lib' not found" error, installing both ri and RDoc. When I type in 'which ruby', I see it installed in the c:/ruby192/bin directory. I had to create a .rvm directory for myself -- it was not created as part of the install.
the --no-rdoc --no-ri worked, of course. The --pre commands installed rc8 instead of the final release.
What gives?
Installing RDoc fixed this problem for me. I had to do this in the gemset I was using.
rvm use rubyversion#gemset
gem install rdoc
After this I could install gems without the "file 'lib' not found" error.
I had the same problem with rails 3.0.9 on my Mac OS X Lion and the "rvm gemset install rails" trick solved it !
$ rvm gemset install rails
installing rails ...
rails installed.
$ rails -v
Rails 3.0.9
Thanks !
I had a similar issue before, while my solution was this: try to use ruby 1.9.2-head instead of ruby 1.9.2-p290.
rvm install ruby-1.9.2-head
rvm use ruby-1.9.2-head --default
And then, install rails 3.1 again.
