Non riesco a eseguire il bundler, continuo a ricevere l'errore

Question

Ho appena trasferito il mio ambiente di sviluppo RoR su Ubuntu. Ho tirato un progetto su cui sto lavorando da github e sto tentando di installare tutte le gemme necessarie. Tuttavia, ogni volta che corro bundle o bundle install o bundle install exec ottengo il seguente errore:

An error occured while installing mysql (2.8.1), and Bundler cannot continue. 
Make sure that `gem install mysql -v '2.8.1'` succeeds before bundling. 

Qualcuno ha affrontato questo particolare dolore? Il tuo aiuto è eternamente apprezzato.

Answer 1

Devi dire a bundler dove trovare la roba mysql-dev sulla tua scatola. Di solito qualcosa di simile a quanto segue funziona:

bundle config build.mysql --with-mysql-config=/usr/local/mysql/bin/mysql_config 

Naturalmente, sarà necessario sostituire il percorso di cui sopra con il percorso effettivo mysql_config. Se non hai mysql_config installato, avrai bisogno del pacchetto mysql-dev installato sul tuo server. Sembra che tu stia probabilmente su un server condiviso, quindi speriamo che il pacchetto di sviluppo sia già installato. In caso contrario, dovrai richiederlo.

Answer 2

La libreria che ti manca, su Ubuntu 14.04 (Trusty) è: libmysqlclient-dev. La riga sotto ha fatto il trucco per me:

sudo apt-get install libmysqlclient-dev
