中止rake db：drop db：create db：migrate命令后，我无法再执行任何Rails或rake DB相关任务。 我已经尝试了几件事，但到目前为止没有任何效果（重新安装ruby，rails，rake，安装和更新包，删除db和架构文件等）。
这是我的数据库。yml：
default: &default
adapter: sqlite3
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
timeout: 5000
development:
<<: *default
database: db/development.sqlite3
test:
<<: *default
database: db/test.sqlite3
production:
<<: *default
adapter: mysql2
encoding: utf8
database: <%= ENV['RDS_DB_NAME'] %>
username: <%= ENV['RDS_USERNAME'] %>
password: <%= ENV['RDS_PASSWORD'] %>
host: <%= ENV['RDS_HOSTNAME'] %>
port: <%= ENV['RDS_PORT'] %>
这是db：drop的堆栈，例如：
$ rake db:drop --trace
** Invoke db:drop (first_time)
** Invoke db:load_config (first_time)
** Invoke environment (first_time)
** Execute environment

感谢任何帮助。谢谢！

能否请您在指定当前Rails环境的情况下尝试运行命令？
样本：rake db:drop RAILS_ENV=development
答案 1 :(得分：0)
好的，老实说，我在这里写下答案有点as愧，但也可能对其他人有帮助！ ：D
根本原因是byebug ...我将Byebug.wait_connection = true设置为，但不知道这也会影响某些rake命令...
