Question

我想在全新安装时测试我的项目是否正确运行。

https://github.com/Nims09/ts_test_ui

对于一个普通的新项目，我克隆它然后执行：

git clone https://github.com/Nims09/ts_test_ui

bundle install

rake db:migrate

rails server

它应该运行，但rake db:migrate给我一个：

ActiveRecord::StatementInvalid: SQLite3::SQLException: no such table: simulations: SELECT  "simulations".* FROM "simulations"  ORDER BY "simulations"."id" DESC LIMIT 1

任何人都可以帮我解决为什么会这样吗？我使用了正确的步骤吗？我提交了一个我不应该拥有的DB文件吗？

完整日志：

Tasks: TOP => db:migrate => environment
(See full trace by running task with --trace)

Answer 1

而不是运行＆＃34; rake db：migrate＆＃34;马上，重置您当前的数据库：

rake db：drop

rake db：create

rake db：migrate

您的迁移表很可能不同步。

这就是我需要的：

     ➤ rake db:migrate
    == 20150717093728 CreateInvitees: migrating ===================================
    -- create_table(:invitees)
       -> 0.0936s
    == 20150717093728 CreateInvitees: migrated (0.0938s) ==========================

我提到的所有命令的输出来自命令行

全新安装我的rails项目会导致SQLite3 :: SQLException
