Question

我在mac上的rails上安装了rvm和ruby。安装完所有的bundle之后，当我运行rails -s命令时，我遇到了这些错误。由于我是ruby on rails的新手，我不知道这些错误是什么意思，我怎么解决它们。

还添加了posts_controller_test.erb的代码

Answer 1

“唯一约束”表示您尝试多次在author email字段上插入相同的值，而您的数据库设置为仅允许唯一值。

没有剩下的代码就无法判断，但看起来你的测试要么没有正确重置，要么你试图多次创建同一个作者。

尝试在posts_controller_test.rb文件中发布代码。

在rails app上运行ruby时出错
