Django的不使用Python 3安裝

-3

def get_filename(root): 
    def wrapper(instance, filename): 
     return (root + filename) 

    return wrapper 

... 

docfile = models.FileField(upload_to=get_filename("/some_dir"))

下面的代碼在以下錯誤

Please note that due to Python 2 limitations, you cannot serialize unbound method functions (e.g. a method declared and used in the same class body). Please move the function into the main module body to use migrations.

我運行的Python 3.4.3與python3 manage.py makemigrations myapp結果運行此，是Django使用我的Python 2安裝？

Django在您的系統上使用Python的默認安裝。這很可能是2.7

如果要使用特定的Python版本，你可以使用該版本明確

~$ python3 django-admin runserver --settings=myapp.settings

開始Django的，但你真正應該做的是安裝virtualenv和創建虛擬環境來運行Django英寸

它允許您指定您想要使用的Python版本，使用不同版本的Django和不同版本的模塊用於不同的項目。所有這些都不會讓你的系統混淆數千種各種模塊的混合版本。

我使用'python3'運行應用程序（更新問題與我使用的命令） –

'python3 --version'說什麼？ – C14L

它說'Python 3.4.3' –

你最好設置python-3.4 virtualenv並從虛擬環境運行你的Django項目。

修改你使用python3命令。對以發動Django的服務器爲例： python3 manage.py的runserver 0.0.0.0:8000 而不是蟒蛇manage.py的runserver 0.0.0.0:8000
