“gem install mysql” failed. This might be another stupid question, but
really block me for couple of days.
I tried gem:
gem install mysql – --with-mysql-config=/usr/bin/mysql_config
and got:
ERROR: Error installing mysql:
ERROR: Failed to build gem native extension.
/usr/local/bin/ruby extconf.rb
–with-mysql-config=/usr/bin/mysql_config
extconf.rb:1: command not found: /usr/bin/mysql_config --cflags
*** extconf.rb failed ***
This might be something wrong with mysql becouse ‘mysql_config’ can not
be located.
[root@localhost ~]# whereis mysql_config
mysql_config:
I also tried mysql-ruby:
[root@localhost mysql-ruby-2.8.1]# ruby extconf.rb
–with-mysql-dir=/usr/bin/mysql
