An error occurred while installing mysql2 (0.3.20), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.20' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  mysql2

I then follow the instructions and 

gem install mysql2 -v '0.3.20' --source 'https://rubygems.org/'

I have tried the solution mentioned here

Ruby gem mysql2 install failing

brew install mysql
Warning: mysql 8.0.11 is already installed and up-to-date
To reinstall 8.0.11, run `brew reinstall mysql`

and then 

gem install mysql2
Building native extensions.  This could take a while...
Successfully installed mysql2-0.5.2
Parsing documentation for mysql2-0.5.2
Done installing documentation for mysql2 after 0 seconds

but when I do bundle install again I still get all of these errors

strangely if I run

 brew reinstall mysql

You can try again using `brew postinstall mysql`
==> Caveats
We've installed your MySQL database without a root password. To secure it run:
    mysql_secure_installation

MySQL is configured to only allow connections from localhost by default

To connect run:
    mysql -uroot

To have launchd start mysql now and restart at login:
  brew services start mysql
Or, if you don't want/need a background service you can just run:
  mysql.server start
==> Summary

which is confusing and truthfully I don't 100% percent understand and may very well be a root of the problem, but don't know.

I have updated to the latest version of XCode and installed the Development Tools

I am on a Mac High Sierra 10.13.4

I would love any advice I could get on it as it is driving me crazy. Please let me know any other information I could provide to ask a better question.

Thank you in advance

I just ran into this problem today. mysql got updated recently, so what worked for me was:

brew install mysql@5.6
brew link mysql@5.6 --force
bundle install

Alternatively, I did not try this solution, but it seems to have worked for other people.

Installing Mysql 2 gem fails




回答2:


I faced the same issue when installing mysql2-0.3.21 on Mac pro.

Below mentioned solution worked for me (run the below mentioned 3 commands in the terminal pointing to your project folder):

brew install mysql

gem install mysql2 -v '0.3.21' -- --srcdir=/usr/local/mysql/include

bundle install



回答3:


This worked for me - macOS Catalina

brew uninstall mysql
gem uninstall mysql2

brew install mysql@5.7
brew link mysql@5.7 --force
gem install mysql2 -v '0.3.21'

# Gemfile
gem 'mysql2', '0.3.21'

bundle update mysql2



回答4:


My MacBook Pro had a disk crashed during upgrade to MacOS Mojave (not pretty!), so I had to reestablish all my code projects afterwards.

One particular project proved extremely hard to get up and running and I've spent several hours today looking for a way to get mysql2-0.3.21 running for an older RoR project; Ruby version 2.1.1p76 with Rails 4.1.1.

Finally, I succeeded by following this advice: https://github.com/brianmario/mysql2/issues/1010#issuecomment-460257986

I did the following steps:

  1. Start by removing all installed versions of mysql2 from your gemset:

    gem uninstall mysql2

  2. Then install MySQL 5.6, I already have MySQL 8.0.17 installed, so 5.6 is installed as a keg only which is fine:

    brew install mysql@5.6

  3. Then install mysql2 version 0.3.21 with the following command:

    gem install mysql2 -v 0.3.21 -- --with-mysql-config=/usr/local/Cellar/mysql@5.6/5.6.42/bin/mysql_config --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include

The OpenSSL part can probably be left out and you can change the mysql2 version number depending on what version of Rails your project is running.

After the above steps I was able to start the Rails console again and query the database:

Loading development environment (Rails 4.1.1)
2.1.1 :001 > User.count
   (18.7ms)  SELECT COUNT(*) FROM `users`  WHERE `users`.`deleted_at` IS NULL
 => 1222
2.1.1 :002 >
