pycharm运行django出错

Question

pycharm 中建立django工程，然后运行其中任意文件，提示
You have unapplied migrations; your app may not work properly until they are applied.
Run 'python manage.py migrate' to apply them.
（可以打开localhost的网页，网页显示：‘
It worked!
Congratulations on your first Django-powered page.
Of course, you haven't actually done any work yet. Next, start your first app by running python manage.py startapp [app_label].
You're seeing this message because you have DEBUG = True in your Django settings file and you haven't configured any URLs. Get to work!
’）

请问这个是在cmd命令中使用吗？（我在cmd中试用了一下：）
我是python3（python2.7也试用了）
然后在cmd中（进入到了python文件目录）输入'python manage.py migrate'
提示：invalid syntax
请问这个如何解决？
