[RUBY] [Rails version control] rails version downgrade


Suddenly, rails new didn't work and it got stuck. .. .. ..


Fetching sassc 2.4.0
Installing sassc 2.4.0 with native extensions

It freezes at the above points and does not proceed. .. .. why. .. ..


Because I upgraded the version of rails


There are many solutions to look for, I ** "I decided to go back one version of rails" ** I just upgraded the version as a trial, so ...


$rails -v 
 Rails   // <-The current version of rails is displayed ①

$ gem uninstall rails 
Select gem to uninstall:
 1. rails-5.2.3
 2. rails-5.2.4
 3. rails-
 4. rails-
 5. rails-
 6. rails-
 7. All versions
> 6     // <-Select the version you want to uninstall ②

$ gem uninstall railties -v ''
Continue with Uninstall? [yN]  y  // <-Enter "y" ③

that's all!!!

Other Play with the sassc gem. There are solutions such as increasing the version of GCC.

[I want to read it together]
