Question

每次运行rake db:migrate时，当我尝试使用rake执行任何其他操作时，会出现以下错误：

(work)doctorly:job_app$ rake
rake aborted!
ActiveRecord::PendingMigrationError: 

Migrations are pending. To resolve this issue, run:

    bin/rake db:migrate RAILS_ENV=test

我继续收到此错误，直到我运行rake db:migrate RAILS_ENV=test。我如何解决此问题，以便每次迁移时都不必运行第二次迁移？

我的默认rails环境是否设置为test？

不，你要求 rails运行你的测试。

当你运行没有参数的rake时，它会运行默认任务，使用Rails意味着运行测试。您需要设置测试环境才能运行它们。如果您不运行测试，请不要运行rake，给它一个实际的命令。
