How to fix error when creating a Rails app?

Trying to put the tracks here, these two guides:
installfest.railsbridge.org/installfest/windows ;
installfest.railsbridge.org/installfest/create_a_r...
In 2 guide stuck at step 4: enter the command 'rails new test_app' in the terminal and climbs this error:

bootsnap.o: In function `atomic_write_cache_file':
C:\RailsInstaller\Ruby2.3.3\lib\ruby\gems\2.3.0\gems\bootsnap-1.4.4\ext\bootsnap/bootsnap.c:484:
undefined reference to `mkstemp'
collect2.exe: error: ld returned 1 exit status
make: *** [bootsnap.so] Error 1

make failed, exit code 2

Gem files will remain installed in
C:/RailsInstaller/Ruby2.3.3/lib/ruby/gems/2.3.0/gems/bootsnap-1.4.4 for
inspection.
Results logged to
C:/RailsInstaller/Ruby2.3.3/lib/ruby/gems/2.3.0/extensions/x86-mingw32/2.3.0/bootsnap-1.4.4/gem_make.out

An error occurred while installing bootsnap (1.4.4), and Bundler cannot
continue.
Make sure that `gem install bootsnap -v '1.4.4' --source
'https://rubygems.org/" succeeds before bundling.

In Gemfile:
 bootsnap

PS Already read that rails 5.2 starautsya only ruby versions
2.2.10
2.3.7
2.4.4
2.5.1
I downloaded 2.5.1, threw in the railsInstaller folder or the folder itself ruby, replaced the files, no purpose, how was ruby 2.3.3 - remained. How to upgrade ruby and to remove the error?
