You should run following command to install NodeJS in Ubuntu
sudo apt-get install nodejs
or run this for OSX
brew install nodejs
Uglifier is a JS wrapper and it needs a JS runtime running or JS interpreter. I would choose to install NodeJS.
In the default Rails Gemfile, the line for the gem 'therubyracer' is commented out. If you uncomment it, you'll get that gem and it should work.
From "Getting Started with Rails":
Compiling CoffeeScript and JavaScript asset compression requires you have a JavaScript runtime available on your system, in the absence of a runtime you will see an execjs error during asset compilation. Usually Mac OS X and Windows come with a JavaScript runtime installed. Rails adds the therubyracer gem to the generated Gemfile in a commented line for new apps and you can uncomment if you need it. therubyrhino is the recommended runtime for JRuby users and is added by default to the Gemfile in apps generated under JRuby. You can investigate all the supported runtimes at ExecJS.
There was an error with creating the db.
The problem is that the Node.js tried to install without sudo in the script:
sudo apt-get install nodejs

I have already tried uninstalling debug_inspector and running bundle install after, but the problem persists.
Can anyone help me please?
If it is still actual. Try to add debug_inspector to your Gemfile.
You need to bundle the gem before start rails server. Follow following steps:
rails new myapp
cd myapp
bundle install
rails server
I deleted all versions of debug inspector first:
gem uninstall debug_inspector
then installed it again with the arch -arm64 flag
arch -arm64 gem install debug_inspector
For some reason, it required to install another gem (which may not be necessary for you)
arch -arm64 gem install rbs -v 2.1.0
And after that, the error has gone.
Why am i getting this error?

fortunately, you don't have to switch to ruby 2.0
there is a solution to this issue, after endless trying...
https://github.com/hwding/sqlite3-ruby-win
Steps
Pre
gem uninstall sqlite3 --all
Source
Download the latest sqlite3-ruby, https://github.com/sparklemotion/sqlite3-ruby
unzip the package
Build
run command-line in the extracted dir
make sure you have your C compiler installed and added to PATH
gem install bundler
bundle install
rake native gem
you'll find a dir named 'pkg' generated
Install
enter dir 'pkg'
gem install --local sqlite3-xxx.gem ('xxx' is version code)
Check
irb
require 'sqlite3'
The issue is that binary sqlite3 gem do not include pre-compiled versions for Ruby 2.1.3
This is mentioned in the sqlite3-ruby mailing list here.
In the folder of your project open terminal and execute:
bundle update sqlite3
bundle update nokogiri
I hope i have helped you ;)
EDIT:
i always recommend using linux/mac for ruby, because some gems may get problematic, because of compiling errors with c
always use bundle to manage your gems, it is much easier*,
you can install it by:
gem install bundler
bundle install - will install all the gems in your Gemfile
the last bundler version is not compatible withe ruby bellow 2.3, so use gem install bundler -v 1.16.4
If you have extracted "exe"s and "dll"s from Sqlite download link to Ruby's bin folder and still have this problem. Try this:
bundle update
gem uninstall sqlite3
Given a choice between multiple versions of sqlite3, choose last option 'All versions'. Enter last number here
Select gem to uninstall:
1. sqlite3-1.3.13
2. sqlite3-1.3.13-x64-mingw32
3. All versions
>3
.
.
If you remove this gem, these dependencies will not be met.
Continue with Uninstall? [yN]
>
y
gem install sqlite3 --platform=ruby
rails s
This should work.
Read through this link for more explanation if above works for you.

Just as the error suggest, you need a runtime(interpreter) for JavaScript on your local machine (no, those in browser wont do).
You can achieve this by installing gems such as therubyracer or run command like 'sudo apt-get install nodejs' just for their dependency
You need to install either therubyracer or nodejs in order to run rails generators. I prefer nodejs, cause it can be used in other cases such as bower or npm
Just add the runtimes in your project
# Gemfile
gem 'therubyracer'

I have installed the gem both locally and at the root level, and I also have navigated to the application folder before issuing the command. Any help would be appreciated!
Webrick will install automatically if you install rails in a correct manner.
Try this link
Here
And if you don't want to install rails again, try to install server using gem command
Dont forget to include the gems in Gemfile and to run "bundle install"
If you are using Rails < 3.1 you need to use version ~> 0.2.7 of the mysql2 gem
Checkout the documentation and search for active record: https://github.com/brianmario/mysql2
I'm not sure if that will help solve this problem directly, but it may solve others that you may encounter.
Just update your bundler, maybe of any-one of the older gem is conflicting with latest one, this type of issues arises.
gem install bundler
and then bundler install
If you find again error, then delete GEM.lock file, then run
bundler install
This may resolve the issue.
