RE: Could not load such file mysql2/mysql2 - Added by kevin deng over 10 years ago

Dear Helwade,

I have installed mysql2 gem with

gem install mysql2 ~~v '0.3.14' --platform=ruby -~~ --with-mysql-lib=/usr/lib64/mysql

multi_json (1.9.2)
mysql (2.9.1, 2.8.1)
mysql2 (0.3.14)
net-ldap (0.3.1)
nokogiri (1.5.11)
polyglot (0.3.4)

and then the mysql2.so has generated, but later i got another issues like below when using : "rake generate_secret_token"
