error while running bundle install
Installing mysql2 (0.3.11) with native extensions
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
...
Make sure that `gem install mysql2 -v '0.3.11'` succeeds before bundling.
when i run Make sure that gem install mysql2 -v '0.3.11'
.I still get the same error.
which OS are you using?
anyway if you are using ubuntu , from this https://github.com/brianmario/mysql2/issues/8 run:
sudo apt-get install mysql-client libmysqlclient-dev
Otherwise for Mac users ,(use brew to install) check this Link , or run:
brew install mysql
then
sudo gem install mysql2
and for windows users check the link below for a solution. Error installing mysql2: Failed to build gem native extension
I would recommend to use the normal command prompt.
有时您需要更新 Ruby 库,请运行以下代码:
sudo gem update --system
Try to install these packages:
sudo apt-get install libmysqlclient-dev
sudo apt-get install bundler
After installing the bundler, run:
gem install mysql2
If the stack trace includes this error:
mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h
Look at what version of ruby you're using with:
ruby -v
Then install the correct version of ruby dev that goes with your version of ruby:
sudo apt-get install ruby2.0-dev
sudo apt-get install ruby2.2-dev
sudo apt-get install ruby2.3-dev
Then:
gem install mysql2
