自学rails部署第一个应用程序到heroku -failure上传 - sqlite3和postgre毛刺 [英] teaching myself rails deploying first app to heroku -failure to upload - sqlite3 and postgre glitch
问题描述
从一开始就开始部署您的应用是一个好主意。我同意。于是我在Heroku上获得了一个帐户，并进行了其他设置，然后创建了我的第一个应用程序，git和这些作品。然后遵循Heroku网站上的所有说明。最后，我使用这个命令来推送我的应用程序到Heroku：
$ g $ push heroku master
本书建议将我应用程序的gem文件中的一行从
gem'sqlite3'
至
gem'sqlite3-ruby'，：group => ：开发
我试过了，然后运行bundle install然后尝试推送应用程序。没有运气
我在控制台上得到这个消息：
$ b $ pre $ 安装sqlite3（1.3.6）时发生错误，和Bundler无法继续。
确保在捆绑之前，gem install sqlite3 -v'1.3.6'`成功。
！
！无法通过Bundler安装宝石。
！
！ Heroku推送被拒绝，未能编译Ruby / rails应用程序
因此，我尝试了Heroku网站建议的 here
改变我的gemfile
：
gem'sqlite3'
至此：
gem'pg'
所以我尝试了这种方法，然后运行捆绑安装。但是那也行不通。我在控制台上看到这条消息：
使用原生扩展安装pg（0.13.2）
Gem :: Installer :: ExtensionBuildError：错误：无法构建gem本机扩展。

有人可以帮我解决这个问题。我打了一个障碍。不知道下一步该怎么做。谢谢
所以这就是工作原理：
1）在机器上安装postgresql 2）对于永久修复 - 转到.bash_rc文件并添加以下内容：
export PATH =/Library/PostgreSQL/9.1/bin/ ：$ PATH
或
只是为了安装丢失的文件并运行bundle命令一次在应用程序的根目录中输入：
PATH = $ PATH：/Library/PostgreSQL/9.1/ bin / bundle install
或
PATH = $ PATH：/Library/PostgreSQL/9.1/bin/ gem install pg
3）现在pg宝石已安装

Im teaching myself rails. Im a programmer but not a web programmer. Im going through Michael Hartl's book here
It mentions that its a good idea to start deploying your app right from the beginning. I agree. So I got an account on Heroku and went through ther setup etc. Then created my 1st app, git and the works. Then followed all the instructions on Heroku's site. Finally I came to pushing my app up to Heroku using this command:
git push heroku master
The book says that there could be problems at this stage because the app on my machine is using sqlite3 while Heroku wants postgresql. The book suggests changing a line in the gem file of my app from
gem 'sqlite3'
to
gem 'sqlite3-ruby', :group => :development
I tried that and then ran bundle install and then tried to push the app. No luck I get this message on my console:
An error occured while installing sqlite3 (1.3.6), and Bundler cannot continue.
Make sure that `gem install sqlite3 -v '1.3.6'` succeeds before bundling.
! ! Failed to install gems via Bundler. ! ! Heroku push rejected, failed to compile Ruby/rails app
So I tried what the Heroku website suggests here
to change my gemfile
from this:
gem 'sqlite3'
to this:
gem 'pg'
so I tried this approach and then ran 'bundle install'. But that didn't work either. I get this message on my console:

Can someone please help me with this. ive hit a roadblock. Not sure what to do next.Thanks
So this is what worked: 1) Install postgresql on the machine
2) For permanent fix - Go to the .bash_rc file and add the following: export PATH = "/Library/PostgreSQL/9.1/bin/":$PATH OR just to install the missing files and run the bundle command one time type this in the root of the app: PATH=$PATH:/Library/PostgreSQL/9.1/bin/ bundle install or PATH=$PATH:/Library/PostgreSQL/9.1/bin/ gem install pg
3) Now the pg gem is installed
