An error occurred while installing mysql2 (0.5.3), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.5.3' --source 'https://rubygems.org/'` succeeds before bundling.
In Gemfile:
mysql2
Führen Sie den folgenden Befehl aus
$ bundle config --local build.mysql2 "--with-cppflags=-I/usr/local/opt/openssl/include"
$ bundle config --local build.mysql2 "--with-ldflags=-L/usr/local/opt/openssl/lib"
Ich habe bestanden, als ich die Bundle-Installation durchgeführt habe
$ bundle install
The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.
