当我运行rake db:test:prepare时,我总是得到以下错误。是什么原因导致的?rake db:create工作正常。

Adam-MacBook-Pro:katy adam$ bundle exec rake db:test:prepare
    rake aborted!

尝试在运行rake命令时指定RAILS_ENV

RAILS_ENV=test bundle exec rake db:test:prepare

字符串

参考这可能是相同的问题rake db:test:load,undefined method `[]' for nil:NilClass
或者试试这个

RAILS_ENV=test rake db:setup

字符串

当我尝试运行一个使用Rails.application.credentials的初始化器时,我在github操作中得到了这个错误
这个错误的原因是因为我忘记了给github action工作流给予我的RAILS_MASTER_KEY,所以github action无法获得在初始化器中使用的凭据。
一旦我added the RAILS_MASTER_KEY to the github repo,它工作。
