Every time I run:

每次我跑:

git push heroku master

I get the following error:

我收到以下错误:

Running: rake assets:precompile
rake aborted!
Can't connect to MySQL server on '127.0.0.1'

I am running

我在跑步

rails -v Rails 3.2.11

and

ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin12.2.0]

I have installed ClearDB via Heroku CLI and it seems to work fine, but I can't figure out this error.

我已经通过Heroku CLI安装了ClearDB,它似乎工作正常,但我无法弄清楚这个错误。

config.assets.initialize_on_precompile = false
