Heroku 部署问题

Question

我正在关注此教程，并按照以下步骤操作部署到 Heroku。

当我从 Heroku 打开应用程序时，我得到的是：

赫罗库 |欢迎使用您的新应用程序！

为什么我的申请没有出现？

编辑：这是我运行heroku日志时得到的结果：

谢谢。

Answer 1

从日志来看，您似乎尚未迁移数据库，因为它正在寻找表 users。要迁移，请在“heroku rake db:migrate VERSION=0”中键入此内容，然后键入“heroku rake db:migrate”。请查看 Heroku 文档

http://devcenter.heroku.com/articles/database

下的内容“迁移到 PostgreSQL 的常见问题”部分。另请查看

http://devcenter.heroku.com/articles/using-the-cli< /a>

，用于可以从终端运行的所有命令。由于你使用的是heroku，所以尝试将你的本地数据库也设置为postgresql，稍后会解决一些小问题。请记住，每次将文件推送到 Heroku 时，如果数据库结构发生更改，您将需要迁移数据库。

Answer 2

您可以使用：

heroku logs

查看服务器上当前发生的情况。

Answer 3

我认为最简单的事情就是重新开始。进入您的应用程序的根目录。例如 myapp 并删除 git repo。

cd sites
cd myApp
git rm -r .git

然后登录 Heroku 并销毁 CMS 中的应用程序。之后，通过进入您的目录，创建一个新的存储库，添加您的目录，作为主提交，创建一个heroku应用程序，然后推送到heroku来创建一个新的heroku Rails应用程序。

git init
git add .
git commit -m 'master'

heroku create
heroku rename myApp
git push heroku master

然后您将需要运行迁移。

heroku rake db:migrate

如果您想将数据从本地计算机推送到生产环境，您将需要使用 taps gem，但请确保将其添加到您的捆绑包中。

gem 'taps'

然后再次运行bundle。

bundle

然后您可以根据需要推送本地数据。

heroku db:push

Answer 4

有点晚了，但我遇到了这个问题。我的 gemfile 中缺少 foreman

Answer 5

如果您关注railstutorial.org
然后在 Gemfile 中注释掉 sqlite 3 (#gem 'sqlite3')

：

git add .

git commit -am "fix heroku"

git push heroku

Answer 6

试试这个，删除你的 package.json 然后 npm init。删除 Heroku 中现有的应用程序，并使用新的 package.json 推送该应用程序。
