Question

我从一开始就跟着Heroku getting started进行了捆绑安装＆＃39; （step＃declare-app-dependencies）并看到一个错误。似乎缺少一些依赖，但我不知道如何找到它们是什么。谁能告诉我应该做什么？

$ bundle install
Fetching gem metadata from https://rubygems.org/...........
Resolving dependencies...
Using rake 10.3.2
Using i18n 0.6.9

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

/usr/bin/ruby2.0 extconf.rb 
mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h


Gem files will remain installed in /tmp/bundler20140919-3839-1mafrop/json-1.8.1/gems/json-1.8.1 for inspection.

An error occurred while installing json (1.8.1), and Bundler cannot continue.
Make sure that `gem install json -v '1.8.1'` succeeds before bundling.

经过数小时的试用，我终于bundle install了。我做了

sudo apt-get purge ruby*
sudo apt-get install ruby
sudo apt-get install ruby-dev
sudo gem install bundler

在这些之后，bundle install没有错误地传递了json-1.8.1。然后错误来了

...
You need to install postgresql-server-dev-X.Y for building a server-side extension or libpq-dev for building a client-side application.
...

所以我做了

sudo apt-get install libpq-dev

再次bundle install。它读了Your bundle is complete!。

供您参考，我也做了以下工作。我不知道Heroku getting started示例是否确实需要它们。

sudo apt-get install postgresql postgresql-contrib
sudo apt-get install libmagickwand-dev python-dev
