Heroku推送失败“预编译资产失败”

[英]Heroku push fails “Precompiling assets failed”

Ruby version: 2.0.0p195 Rails: 4.2.0beta4 Ruby版本:2.0.0p195 Rails:4.2.0beta4

So I tried to run rake assets:precompile. 因此,我尝试运行rake asset:precompile。 (Sounded like a good idea) And I get the following trace: (听起来不错)我得到以下跟踪:

I'm learning Ruby on Rails so please assume that I am missing the obvious. 我正在学习Ruby on Rails,因此请假设我缺少明显的东西。

EDIT: 编辑:

you're right trueinViso - I did not specify postgres in database.yml. 您是对的trueinViso-我没有在database.yml中指定postgres。 What should I write? 我应该写什么? This is database.yml: 这是database.yml:

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
#
default: &default
  adapter: sqlite3
  pool: 5
  timeout: 5000

development:
  <<: *default
  database: db/development.sqlite3

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  <<: *default
  database: db/test.sqlite3

production:
  <<: *default
  database: db/production.sqlite3

What I did: I changed the development database to use postgres 'pg'gem. 我做了什么:我将开发数据库更改为使用postgres'pg'gem。 (Which is probably not useful. I actually don't know if it is relevant). (这可能没有用。我实际上不知道它是否相关)。

Most importantly, after doing the above, I changed database.yml to (the adapter was wrong "postgresl": 最重要的是,完成上述操作后,我将database.yml更改为(适配器错误的“ postgresl”:

development:
  adapter: postgresql
  host: localhost
  database: pqqq
  username: pqqqq
  password: pqqqq

test:  
  adapter: postgresql
  encoding: unicode
  database: testdb_pow
  pool: 5
  username: parseb
  password: testtt

Than I ran rake asstes:precompile and afterwards git push heroku master and it worked. 比我跑了耙asstes:precompile,然后git push heroku master,它起作用了。 (Do not forget to migrate the database on heroku - heroku run db:migrate.) (不要忘记在heroku上迁移数据库-heroku运行db:migrate。)

You didn't need run rake assets:precompile . 您不需要运行rake assets:precompile

Just go to config/production.rb and set serve_static_assets = true . 只需转到config/production.rb并设置serve_static_assets = true

# Disable Rails's static asset server (Apache or nginx will already do this).
  config.serve_static_assets = true

When you push to heroku again, the assets will work. 当您再次按下heroku时,资产将起作用。 That was the solution to me. 那是我的解决方案。
