我删除了一个pip包,rm -rf命令认为该包将被删除.现在该包已被删除,但它仍然显示在内pip list,我无法将其删除,pip uninstall也无法更新pip install --upgrade.

我想完全删除它.谁能告诉我怎么样？

包是psycopg2.

如果我尝试卸载:

hammad@hammad-P5QL-E:~$ pip uninstall psycopg2
Can't uninstall 'psycopg2'. No files were found to uninstall.

这是psycopg2所在的目录,/usr/lib/python2.7/dist-packages我rm -rf来自同一目录.

TIA

我的项目在Django 1.5.4上运行,我想升级它.我做了pip install -U -I django,现在pip freeze显示Django 1.6.5(显然django已升级,我在virtualenv)但我的项目仍在使用Django 1.5.4.我该如何使用升级版？

更新:感谢您的评论.我尝试了一切,但遗憾的是没有任何工作,我不得不重新部署应用程序.

希望有人解释为什么会这样.

我是一个新手,我正在django制作一个网络应用程序,在其中我有一个显示任务对象列表的页面.

我想知道如何在不刷新页面的情况下更新此对象列表,这样如果创建了新对象,它将自动显示在页面上.

我对ajax有一些了解但是,我不知道如何实现这个目标.

TIA

AttributeError当我尝试在WebFaction生产服务器上运行以下代码时,我得到一个例外(它在开发中工作):

#forms.py

class UserRegistrationForm(forms.ModelForm):
    full_name = forms.CharField(widget=forms.TextInput(attrs={'placeholder':'Your full name'}))
    email = forms.CharField(widget=forms.EmailInput(attrs={'placeholder':'Activation email will be sent'}))
    password = forms.CharField(widget=forms.PasswordInput)
    meal_package = forms.ModelChoiceField(queryset=Package.objects.all(), widget=forms.RadioSelect(), empty_label=None)
    mobile = forms.CharField(widget=forms.TextInput(attrs={'placeholder':'You will recieve a call on this number'}))
    area_name = forms.CharField(widget=forms.TextInput(attrs={'placeholder':'Name of your area'}))
    building_name = forms.CharField(widget=forms.TextInput(attrs={'placeholder':'Name of your building'}))
    room_no = forms.CharField(widget=forms.TextInput(attrs={'placeholder':'Your apartment number'}))

    class Meta:
        model = User
        fields = ['full_name', 'email', 'password', 'meal_package' ,'mobile', 'area_name', 'building_name', 'room_no']

这是错误:

    class UserRegistrationForm(forms.ModelForm):
