python - Macbook 10.8でpython manage.py runserverが機能しない

Question

次のコマンドの実行

$python2.6 manage.py runserver 

これに出力を与えます：

Traceback (most recent call last):
  File "manage.py", line 8, in <module>
    from django.core.management import execute_from_command_line
ImportError: No module named django.core.management

私はそこに多くの解決策を試しましたが、それらは役に立ちません。

pipを使用してdjangoを再度インストールしようとすると、

$ pip install django

次の出力が得られます。

Requirement already satisfied (use --upgrade to upgrade): django in /Library/Python/2.7/site-packages
Cleaning up...

そして、しようとしている

$ pip freeze

次の出力が得られます。

Django==1.5.4
MySQL-python==1.2.4
...
...
...
wsgiref==0.1.2
xattr==0.6.2
zope.interface==3.5.1

どうすればいいのかわからない？これを正常に実行しようとして全体を無駄にしたのを助けてください。ありがとう。

アップデート：

走ってみたところ

$ python2.7 manage.py runserver

次のエラーが表示されます
