mysql2 将 mysql 升级到 8 后无法使用
mysql2 not working after upgrading mysql to 8
我最近将 mysql 从 mysql5.7
更新为 mysql8.0.4
。我将 mysql2 gem 从 0.4.9
更新为 0.5.3
之后我开始收到以下错误:
/Users/user/.rvm/gems/ruby-2.4.0@talent_now/gems/activerecord-5.1.4/lib/active_record/connection_adapters/connection_specification.rb:188:in `rescue in spec':
Specified 'mysql2' for database adapter, but the gem is not loaded. Add `gem 'mysql2'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord). (Gem::LoadError)
我试图将 mysql2 降级到 0.4.9
但后来我得到了
/usr/local/Cellar/mysql/8.0.25_1/include/mysql/mysql.h:187:3: note: 'MYSQL_DEFAULT_AUTH' declared here
MYSQL_DEFAULT_AUTH,
^
client.c:1315:38: error: use of undeclared identifier 'MYSQL_SECURE_AUTH'; did you mean 'MYSQL_DEFAULT_AUTH'?
return _mysql_client_options(self, MYSQL_SECURE_AUTH, value);
^~~~~~~~~~~~~~~~~
MYSQL_DEFAULT_AUTH

我在 mac catalina
中使用 Rails5.1.4
mysql2 0.5.x
与 Rails5.1.4
不兼容,
所以我将 Rails
更新为 5.1.7
以使其工作。
mysql2 0.5.x works with Rails / Active Record 4.2.11, 5.0.7, 5.1.6, and higher.
mysql2 文档中提到了以上内容。
