Heroku错误：没有这样的文件加载 - sqlite3/sqlite3_native

Question

我在本地mashine上使用Mysql。我尝试推送数据库时遇到问题。 我已经安装了水龙头。

Home@PC /c/rails/konkurranceportalen (master) 
    $ heroku db:push 
    Taps Load Error: no such file to load -- sqlite3/sqlite3_native 
    You may need to install or update the taps gem to use db commands. 
    On most systems this will be: 

    sudo gem install taps 

更新我现在得到以下错误：

Ruby.exe system error 
The program could not be started because sqlite3.dll is missing on the computer. 

我的数据库阳明：

# SQLite version 3.x 
# gem install sqlite3-ruby (not necessary on OS X Leopard) 
# gem 'mysql', '2.8.1' 

development: 
    adapter: mysql 
    database: konkurranceportalen 
    encoding: utf8 
    pool: 5 
    username: root 
    password: 
    socket: C:/xampp/mysql/bin/mysqld.sock 
    host: 127.0.0.1 

# Warning: The database defined as "test" will be erased and 
# re-generated from your development database when you run "rake".

test: 
    adapter: mysql 
    database: rails_t 
    encoding: utf8 
    pool: 5 
    username: root 
    password: 
    socket: C:/xampp/mysql/bin/mysqld.sock

Answer 1

我没有下载sqlite.dll这里http://www.sqlite.org/download.html 并没有将其粘贴在红宝石/ bin和MYAPP的/ tmp /插座 然后我可以运行的Heroku DB：推

Answer 2

您需要先安装水龙头宝石。它应该在那之后自动工作。

看看你的database.yml文件是否配置正确。

或者只是使用所需的细节

 
$ heroku db:push mysql://root:mypass@localhost/mydb 

填写上面的命令。

Answer 3

简单地增加

gem 'sqlite3' 

到我的'开发'组内的Gemfile为我修复了它。
