Ich folgedieses Tutorial, aber es schlägt fehl, wenn ich versuche, mich an Heroku zu wenden. Es scheint, dass "sqlite3.h" fehlt. Ich bin neu in der Entwicklung, daher bin ich mir nicht sicher, welche Informationen den Leuten helfen, das Problem zu diagnostizieren. Hier ist also alles :). Ich verwende Mac OS X 10.7 Lion. Hier sind die Versionen von allem, mit dem ich arbeite:

<code>Amits-MacBook-Air-2:demo_app amitgupta$ ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.3.0]
Amits-MacBook-Air-2:demo_app amitgupta$ rails -v
Rails 3.2.3
Amits-MacBook-Air-2:demo_app amitgupta$ sqlite3 -version
3.7.11 2012-03-20 11:35:50 00bb9c9ce4f465e6ac321ced2a9d0062dc364669
Amits-MacBook-Air-2:demo_app amitgupta$ heroku -v
2.25.0
Amits-MacBook-Air-2:demo_app amitgupta$ port -v
MacPorts 2.0.4
Entering interactive mode... ("help" for help, "quit" to quit)

</code>

Wenn ich versuche, mich an Heroku zu wenden:

<code>Amits-MacBook-Air-2:demo_app amitgupta$ heroku create --stack cedar
Creating floating-stream-8009... done, stack is cedar
http://floating-stream-8009.herokuapp.com/ | [email protected]:floating-stream-8009.git
Amits-MacBook-Air-2:demo_app amitgupta$ git push heroku master
</code>

Folgendes bekomme ich:

<code>Counting objects: 119, done.

Compressing objects: 100% (104/104), done.
Writing objects: 100% (119/119), 33.74 KiB, done.

Wenn ich mache:

<code>Amits-MacBook-Air-2:demo_app amitgupta$ sudo port install sqlite3 +universal
</code>

Ich bekomme:

<code>Password:
--->  Computing dependencies for sqlite3
--->  Cleaning sqlite3
</code>

Als nächstes habe ich versucht:

<code>Amits-MacBook-Air-2:demo_app amitgupta$ sudo gem install sqlite3 -v '1.3.6'
</code>

Und bekomme:

<code>Building native extensions.  This could take a while...
Successfully installed sqlite3-1.3.6
1 gem installed

</code>

Dann:

<code>Amits-MacBook-Air-2:demo_app amitgupta$ bundle install
</code>

gibt:

<code>Using rake (0.9.2.2)

</code>

Dann versuche ich es nochmal mit Heroku, bekomme aber das gleiche Problem. Vielleicht hat es etwas mit der Diskrepanz zwischen dem ersten Befehl "Creating floating stream 8009" und dem zweiten Befehl "Einige Verweise konnten nicht an" [email protected]: blazing-mountain-3659.git "gesendet werden" zu tun?
