无法推送到heroku（不会编译ruby应用程序）

Question

当我做“git push heroku master”时，在日志结尾处出现此错误。

remote: ! 
remote: !  Precompiling assets failed. 
remote: ! 
remote: !  Push rejected, failed to compile Ruby app. 
remote: 
remote: !  Push failed 
remote: Verifying deploy... 
remote: 
remote: !  Push rejected to johnz-project. 
remote: 
To https://git.heroku.com/johnz-project.git 
! [remote rejected] master -> master (pre-receive hook declined) 
error: failed to push some refs to 'https://git.heroku.com/johnz-project.git' 

还了日志中的某个地方，我看到了这一点：

Can't find file jquery-ui/effect-blind 

不知道为什么，因为我加入了jQuery UI的护栏宝石我的Gemfile，并在应用中工作发展。

的application.js

//= require jquery 
//= require jquery-ui/effect-blind 
//= require jquery_ujs 
//= require bootstrap 
//= require lightbox-bootstrap 
//= require custom 
//= require turbolinks 
//= require_tree . 

application.scss

@import "bootstrap"; 
@import "lightbox-bootstrap"; 
@import "font-awesome"; 
@import "jquery-ui"; 

请帮帮忙！

后做事 “的Heroku运行耙分贝：迁移” 我在堆栈跟踪某个地方得到这个错误：

ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR: relation "categories" does not exist: 
CREATE TABLE "products" ("id" serial primary key, "title" character varying, 
"description" character varying, "category_id" integer, "picture" character varying, "video" character varying, "created_at"  
timestamp NOT NULL, "updated_at" timestamp NOT NULL, CONSTRAINT "fk_rails_fb915499a4"               
FOREIGN KEY ("category_id") REFERENCES "categories" ("id"))

应该怎么办这样的：

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

它看起来像你的资产没有在heroku上编译。

按照以下代码：

配置/环境/ production.rb

config.assets.compile = true 

然后运行命令：

RAILS_ENV=production rake assets:precompile 

然后按所有编译后的文件与menifest文件的Heroku。
