ruby-on-rails - "heroku db:push"给我 : "Taps Load Error: no such file to load -- sqlite3..."

Question

通过这样做:

bundle exec heroku db:push

我知道了:

 !    Taps Load Error: no such file to load -- sqlite3
 !    You may need to install or update the taps gem to use db commands.
 !    On most systems this will be:
 !    
 !    sudo gem install taps

这是我的 database.yml 文件:

development:
  adapter: mysql2
  encoding: utf8
  database: g_dev
  pool: 5
  username: root
  password: 

Answer 1

我调试过了。

我需要将 gem 'sqlite3' 放入 gemfile 中。

由于 cli.rb (taps-0.3.24) 中的第 10 行:

require 'optparse'
require 'tempfile'
require 'taps/monkey'
require 'taps/config'
require 'taps/log'
require 'vendor/okjson'

Taps::Config.taps_database_url = ENV['TAPS_DATABASE_URL'] || begin
  # this is dirty but it solves a weird problem where the tempfile disappears mid-process
  require 'sqlite3'

它在水龙头源代码中...... :(我别无选择
