Can't push to heroku - sqlite3.h is missing

Question

first post here =) Thanks in advance for helping out, any help is cool at this point!

1- I've searched quite a lot and tried loads of stuff before considering posting on stackoverflow..

2- When running

   git push heroku master

I get this:

   checking for sqlite3.h... no
   sqlite3.h is missing. Try 'port install sqlite3 +universal'
   or 'yum install sqlite-devel' and check your shared library search path (the
   location where your sqlite3 shared library is located).

3- I checked the Gemfile: production and dev/test are well configured for pg and sqlite3 respectively

4- Sqlite3.h is here:

   pcbo$ ls -l /usr/include/sqlite3.h
   -rw-r--r--  1 root  wheel  322724  7 Dec  2011 /usr/include/sqlite3.h

5- Forgot to mention i'm using mac os x..

6- Output of: pcbo$ git push heroku master

    Counting objects: 71, done.
    Delta compression using up to 4 threads.
    Compressing objects: 100% (58/58), done.

Answer 1

[Update1]

From your git push log, Here is your culprit:-

 Installing sqlite3 (1.3.6) with native extensions

So, As I initially suspected, blunder is trying to load sqlite3 gem which WILL fail on heroku. as said earlier this can happen because of two reasons

1. Gemfile is wrongly configured to require sqlite3 gem in production
2. Some other gem has dependency on sqlite3 gem. use the gem dependency command to show the dependencies of gem & remove that gem which depends on sqlite3.

After that, rerun bundle install & it would work.

---[End Update1]---

The only reason you can get this error is when, trying to use sqlite3 database on heroku which is not supported. so closely inspect your Gemfile and make sure its setup similar to this

group :production do
  gem 'pg'
end
group :development, :test do
  gem 'sqlite3'
end

And then do bundle install to regenerate your Gemfile.lock. now, try to push heroku. if you still get this error, then probably some gem that you are using has listed sqlite3 as hard-coded dependency in its gemspec file. so in effect, sqlite3 is being loaded even though its not present in gemfile. so verify this, run the following command on localhost:

$ bundle install | grep sqlite

Lastly, after trying this. it doesn't work. Post back the complete log of git push heroku master & output of heroku logs.

Answer 2

Seems that the sqlite library is missing. Try and find it with

whereis sqlite3.h

If it is in your system, try:

sudo gem install sqlite3-ruby -- --with-sqlite3-include=<"url where it is(for eg: /usr/include)">
