Question

我试图在我的服务器上进行迁移但是当我执行rake db：migrate时我得到了这个代码。我在电脑上做得很好。

Please install the sqlite3 adapter: `gem install activerecord-sqlite3-adapter` (sqlite3 is not part of the bundle. Add it to Gemfile.)

有人知道该怎么办吗？

非常感谢

Answer 1

将其添加到Gemfile

gem 'sqlite3'

然后

bundle install
rake db:create
rake db:migrate

如果它没有帮助，那么替换行

gem 'sqlite3'

与

gem 'sqlite3', '1.3.9'

并运行上述命令。如果它没有帮助，那么如果没有安装sqlite，则在你的系统上安装sqlite并重复上述过程。

Answer 2

最好你能gem pg，因为它将支持所有数据库适配器，

添加Gemfile

gem 'pg'

然后

bundle install

然后开始迁移。

Rake在迁移到服务器时中止
