When I try to start the application I created after a long time, the following error is output and the application does not start. Record the corresponding steps. (There were problems such as the version not matching, but I will write this in a separate article.) It's a very long error, so be careful.
This is the error that was output when the rails -s command was executed in the root path of the app.

Since the amount of error output is very large, I thought that it might be faster to rebuild the environment, but I decided to set a time and respond.
--(1) Follow the description and execute "gem pristine nokogiri --version 1.10.1". --Try executing with bundle exec added. --bundle install --path run run --Result-> The same error is output. --② Try executing "bundle update" once from the background. --Result-> Only error 2 is output </ font>
Since other apps are started as a background, when installing with the homebrew command, it fails on the way. Along with this, after recovering the os, Rails-related applications such as Xcode were reconfigured. It is assumed that error 1 was resolved by "bundle install" because the Gem environment was also changed by these operations.
How to deal with error 2 will be posted in a separate article.
