I encountered this issue when working on a Ruby 2.2.3 application.
I had previously uninstalled the MySQL database server on my machine, since I did not need it. However, I still needed the mysql2 gem since my application was connecting to another application's MySQL database to pull data.
However, when I try to run the bundle
command I get the error:
Could not load OpenSSL.
You must recompile Ruby with OpenSSL support or change the sources in your Gemfile from 'https' to 'http'. Instructions for compiling with OpenSSL using RVM are
available at rvm.io/packages/openssl.
Here's how I solved it:
The issue was caused by removing the libssl-dev
library when I was uninstalling the MySQL database server on my machine and its libraries.
First I ran the command below to reinstall ruby
since I installed it using rvm
:
rvm reinstall ruby-2.2.3
This raised an error:
Making gemset ruby-2.2.3 pristine............................................./-
.'command gem pristine --extensions mysql2 --version 0.5.3' failed, you need to fix these gems manually.
.
Error running '__rvm_with ruby-2.2.3 gemset_pristine',
please read /home/promisepreston/.rvm/log/1630094455_ruby-2.2.3/gemset.pristine-ruby-2.2.3.log
Next, I tried to install the mysql2 gem:
gem install mysql2
Then I ran into this error:
Building native extensions. This could take a while...
ERROR: Error installing mysql2:
ERROR: Failed to build gem native extension.
mysql client is missing. You may need to 'sudo apt-get install libmariadb-dev', 'sudo apt-get install libmysqlclient-dev' or 'sudo yum install mysql-devel', and try again.
Finally, I installed the mysql client library using the command:
sudo apt-get install libmysqlclient-dev
Note: This also installs the libssl-dev
library alongside.
And everything worked fine.
That's all.
