I recommend you just use rubyinstaller

It is recommended by the official Ruby page - see https://www.ruby-lang.org/en/downloads/

Ways of Installing Ruby

We have several tools on each major platform to install Ruby:

• On Linux/UNIX, you can use the package management system of your
  distribution or third-party tools (rbenv and RVM).
• On OS X machines, you can use third-party tools (rbenv and RVM).
• On Windows machines, you can use RubyInstaller.

Ruby install gem offline in Windows

Got the reason. I ran all commands in Windows PowerShell.

Now I tried to do it in usual cmd.exe - and it just worked.

Just for a case here is how I installed sqlite3.gem: followed instructions from https://stackoverflow.com/a/16023062 and executed command:

gem install sqlite3-1.3.10.gem --local --platform=ruby -- '--with-sqlite3-dir="c:/programs/sqlite" --with-sqlite3-lib="c:/programs/sqlite/.libs" --with-sqlite3-include="c:/programs/sqlite"'

Thank you for comments, they helped to correct the command.
