Failed to install “Mysql2” version 0.5.2












2















I tried all methods of here.
But still, the same error occurs.



An error occurred while installing mysql2 (0.5.2), and Bundler cannot
continue.
Make sure that gem install mysql2 -v '0.5.2' --source 'https://rubygems.org/'
succeeds before bundling.


My spec is:




  • MacOS Mojave 10.14.1


  • Ruby 2.5.3p105


  • Mysql 8.0.12 with Homebrew



Gemfile:



gem "rails"
gem "mysql2", "0.5.2"


Could you kindly tell me a solution?

This is a very good post. I was facing the same issue using mac. What I ended up doing was the following.




  1. I changed the permission for the Gemfile. I used chmod 755 Gemfile.


  2. I used sudo bundle install. This allowed me to install all the gems in the Gemfile.


  3. I did a rake db:create and rails server.



Got things working. Hope it fixes your issue too.
