Question

我尝试使用git push heroku master -f命令将我的Rails应用程序推送到Heroku，我得到了这个：

我再次尝试bundle update和bundle install并运行git push heroku master -f，但它仍无效。

我也尝试删除我的Gemfile.lock文件，再次运行bundle update和bundle install，git add和git commit并运行git push heroku master -f但它也没有为我工作。

这是我的Gemfile btw：

source 'https://rubygems.org'

gem 'rails',            '4.2.0'
gem 'bootstrap-sass',   '3.2.0.0'
gem 'sass-rails',       '5.0.2'
gem 'uglifier',         '2.5.3'
gem 'coffee-rails',     '4.1.0'
gem 'jquery-rails',     '4.0.3'
gem 'turbolinks',       '2.3.0'
gem 'jbuilder',         '2.2.3'
gem 'sdoc',             '0.4.0', group: :doc
gem 'font-awesome-sass'

group :development, :test do
  gem 'sqlite3',     '1.3.9'
  gem 'byebug',      '3.4.0'
  gem 'web-console', '2.0.0.beta3'
  gem 'spring',      '1.1.3'
end

group :production do
  gem 'pg',             '0.17.1'
  gem 'rails_12factor', '0.0.2'
end

这是我的.gitignore文件：

# See https://help.github.com/articles/ignoring-files for more about ignoring files.
#
# If you find yourself ignoring temporary files generated by your text editor
# or operating system, you probably want to add a global ignore instead:
#   git config --global core.excludesfile '~/.gitignore_global'

# Ignore bundler config.
/.bundle

# Ignore the default SQLite database.
/db/*.sqlite3
/db/*.sqlite3-journal

# Ignore all logfiles and tempfiles.
/log/*
!/log/.keep
/tmp

Answer 1

按照步骤 -

步骤1：手动或从以下命令 -

中删除项目中的Gemfile.lock

rm -rf ~/.bundle/ ~/.gem/ .bundle/ Gemfile.lock

第2步：然后bundle install

第3步：git add .

第4步：git commit -m "commiting Gemfile.lock"

第5步：git push heroku master -f

Answer 2

首先做一个＆＃34; git pull＆＃34;合并，然后再次推动。或尝试执行此操作： rake assets:precompile git add . git commit -m "Add precompiled assets for Heroku" git push heroku master -f

Answer 3

我很确定你没有在gemfile中指定ruby版本。我相信Heroku需要这个。所以它使用ruby 2.0作为heroku默认值，然后尝试加载1.9.7的gem作为Bundler默认值。

如果这是正确的，在gemfile中指定ruby版本号将解决问题。见http://devcenter.heroku.com/articles/ruby-versions

Answer 4

确保您在本地安装了posgresSQL：
- on MAC：
brew install postgresql
- 在Ubuntu上：
sudo apt-get install libpq-dev
- RHEL系统：
yum install postgresql-devel
在您当地的
上发布postgres
pg_ctl -D / usr / local / var / postgres start＆amp;＆amp; brew service star postgresql
让我们确保Postgres已安装并正在运行

postgres -V
在终端上登录Postgresql

sudo -u postgres psql postgres

（您可能需要提供密码＆＃39; root＆＃39;）

创建用户与大多数标准权限模型一样，Postgres实际上并不直接管理用户或组。相反，它直接管理它所谓的角色

创建角色testpostgres WITH LOGIN PASSWORD＆＃39; root＆＃39;;
为我们的新用户分配createDB权限

ALTER ROLE testpostgres CREATEDB;
设置新用户的密码

\ password testpostgres
创建数据库

创建数据库yourDBName;
使用Postico（eggerapps.at/postico/）和UI来管理PostgresDB。

上面的用户用户设置通过Postico登录您的数据库。

登录后，您可能会看到如下图像

配置您的database.yml

将所有适配器：sqlite3更改为适配器：postgresql

通过在database.yml文件中添加两个字段来提供用户名和密码登录到DB：

默认值：＆amp;默认值适配器：postgresql pool：＆lt;％= ENV.fetch（＆＃34; RAILS_MAX_THREADS＆＃34;）{5}％＆gt; 主持人：localhost 用户名：testpostgres 密码：root 超时：5000

可以将数据库名称放在字段数据库中，例如：

production:
  <<: *default
  database: railsapp

运行

rake db：create

rake db：migrate
再次提交代码并将代码推送到Heroku。应该没问题。
