我不明白该错误。我之前做过一个项目，但是virtualenv遇到了一些问题，所以我用virtualenv创建了另一个目录，然后将所有代码复制粘贴到所有文件中，包括manage.py settings.py和urls.py。我在virtualenv中使用命令行启动了应用程序，然后复制了先前应用程序中粘贴的所有代码。
manage.py文件

更改此行
$('.tabledit-confirm-button').click(function () {
if(confirm("Are you sure, you want to delete this category?")) {
var data = $(this).closest('tr').find('input[type=hidden]').val();
var $this = $(this);
var url = '{{ route("category.destroy", ":data") }}';
url = url.replace(':data', data);
$.ajax({
method: "POST",
url: url,
dataType: 'json',
data: { _token:"{{ csrf_token() }}", _method:"DELETE"},
success(response){
success(response.data);
$this.parent("tr").remove()
},
error: function(response){
let data = response.responseJSON.errors;
$.each( data, function( key, value ) {
$( "<span class='validation-errors text-danger'>"+value+"</span>" ).insertAfter( "#"+key );
});
}
});
}
});
到
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'quicktt.settings')
Django正在尝试在os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'quick_timetable.settings')
内查找settings.py文件，该文件不存在，因为这是一个新的Django项目，并且设置文件位于quicktt内部。
