This is a summary of solutions to small errors that occurred when introducing gems and bcrypt for password encryption.
And when I ran bundle install, An error occurred while installing bcrypt (3.1.13), and Bundler cannot continue. Error occurs. Next, it is written in the error message, gem install bcrypt -v'3.1.13' When I execute, Permission denied occurs this time
Execute the following code to see if Permission is the turn of sudo
$ sudo gem install bcrypt
Now the error on bundle install disappears and bcrypt is added!
I successfully overcame error 1 and restarted the localhost browser, but this error
Speaking of which, I remembered that there was a long time ago like this, and re-executed rails s.
Then I passed! !!
This time there were a lot of small errors when introducing bcrypt ~
