Django学习中遇到的问题（1）

下面是报错的问题:

ModuleNotFoundError: No module named ‘mylibdjango’

Traceback (most recent call last):

两个问题是连在一起出现的，我在网上搜了好久也没找到为什么？
但是后来仔细查看了一下发现问题出在这儿：

INSTALLED_APPS = [
‘mylib’
‘django.contrib.admin’,
‘django.contrib.auth’,
‘django.contrib.contenttypes’,
‘django.contrib.sessions’,
‘django.contrib.messages’,
‘django.contrib.staticfiles’,
]

激活应用mylib的时候我忘记写逗号了。
