Django: runserverするときにSyntax Errorが発生します。

Question

#前提
Djangoで開発されている方のGithub repositoryからcloud9上にcloneして、マークアップ言語をいじろうとしています。

#問題
最初にpython manage.py runserverしようとしたところで問題が発生します。

https://stackoverflow.com/questions/42611593/how-to-solve-syntaxerror-on-autogenerated-manage-py

この方とまったく同じ問題が発生しています。
stackoverflowにある回答を試してみましたが、

  File "manage.py", line 15
     ) from exc
          ^
SyntaxError: invalid syntax

のSyantaxErrorが一向に消えません。
どのように行えばよいでしょうか。何卒宜しくお願い致します！！

#!/usr/bin/env python

        ) from exc
    execute_from_command_line(sys.argv)

    execute_from_command_line(sys.argv)

消せばいいんじゃないですかね？

少し進んだのですが、今度は
```

```

で躓いています…

```
"""goen URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/2.0/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path, include

urlpatterns = [
path('admin/', admin.site.urls),
path('accounts/', include('accounts.urls')),
path('social/', include('socials.urls')),
]

```

No module named urls
はどこに何を加えるべきなのでしょうか。

重ねてお手数おかけしますがお願いできると嬉しいです！

これは下のurlpatternsの中のurlが間違っているということでしょうか

```urls.py
from django.contrib import admin
from django.conf.urls import path, include

urlpatterns = [
path('admin/', admin.site.urls),
path('accounts/', include('accounts.urls')),
path('social/', include('socials.urls')),
]
```

何度もすみません！

Answer 2

2系のPythonを使用されていませんか。

python manage.py ...ではなく、python3 manage.py...だとどうでしょうか。

[naoya0206k1]

ご返信ありがとうございます！

```
~/workspace (environment) $ python3 manage.py migrate
Traceback (most recent call last):
File "manage.py", line 9, in <module>
from django.core.management import execute_from_command_line
ModuleNotFoundError: No module named 'django'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "manage.py", line 12, in <module>
"Couldn't import Django. Are you sure it's installed and "
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?
```

```
$ python --version
Python 2.7.6
```

この場合はどうすればいいのでしょうか。

自分なりに進めて
```
$pip install --user django
```
↓
```
$ python3 manage.py migrate
ModuleNotFoundError: No module named 'social_django'
```

で止まってしまっています...

pipでのインストールですが、
pip3 install ライブラリ名
でも大丈夫だと思います。

cloneしたプロジェクトは、social_djangoが必須のものと思われますので、
pip3 install social-auth-app-django
としてみてください。
