Question

运行rake db.seed时出现以下错误，我该如何解决？

（我尝试删除seed.rb并重新创建它，但它没有用）

  耙子流产了！不知道如何构建任务'db.seed'

背景资料：

我正在关注tutorial，其中我在db.seed文件中创建了一个模拟用户。

User.create！电子邮件：'test@test.com'，密码：'密码'， password_confirmation：'password'

现在当我运行命令rake db：seed时，我得到上面的错误。如何成功运行命令？

为了避免将来出现此类错误，您可以从项目目录中键入bundle exec rake -T以列出Rails应用程序的所有可用rake任务：

➜  bundle exec rake -T
rake db:create                          # Creates the database from DATABASE_URL or config/database.yml for the current RAILS_ENV (use db:create:all to create all databa...
rake db:drop                            # Drops the database from DATABASE_URL or config/database.yml for the current RAILS_ENV (use db:drop:all to drop all databases in...
rake db:fixtures:load                   # Load fixtures into the current environment's database
rake db:migrate                         # Migrate the database (options: VERSION=x, VERBOSE=false, SCOPE=blog)
rake db:migrate:status                  # Display status of migrations
rake db:rollback                        # Rolls the schema back to the previous version (specify steps w/ STEP=n)
rake db:schema:cache:clear              # Clear a db/schema_cache.dump file
rake db:schema:cache:dump               # Create a db/schema_cache.dump file
rake db:schema:dump                     # Create a db/schema.rb file that is portable against any DB supported by AR
rake db:schema:load                     # Load a schema.rb file into the database
rake db:seed                            # Load the seed data from db/seeds.rb

然后，只需复制您要查找的任务（在本例中为rake db:seed）并运行rake任务！
