macsn@MacsndeMac U_crawler % python manage.py runsever

Traceback (most recent call last):

  File "manage.py", line 17, in "Couldn‘t import Django. Are you sure it‘s installed and "
ImportError: Couldnt import Django. Are you sure its installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?

这个问题纠结我一天,结果打开方式不对,??  ??  辽~

/***我的错误示范:

出现这个问题,我首先想到Mac下自带python2.7,而我自己安装了一个python3.8,终端执行命令:which python 显示系统自带解析路径,于是我就想怎么把它改成自定义的路径,按照网上各路博客把环境变量bash_profile文件改了一通

but 依然不行,然后我就想一不做二不休,把python2.7删了,只剩下自己装的python3.8总可以了把,按照网上各路博客把删除Mac自带python2.7的终端代码执行了一通,然后macsn@MacsndeMac ~ % which python /usr/bin/python

macsn@MacsndeMac ~ % emmmmmmm 要疯辽 ,这边建议亲不要随便删除Mac自带的python呢,虽然版本低但是它系统对他依赖强啊

正确打开方式:

python3 manage.py runserver
macsn@MacsndeMac U_crawler % python3 manage.py runserver

You have 17 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.

Django version 3.0.6, using settings U_crawler.settings
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

对加个3就行了,pip指令没法用的时候pip3试试

Django要2.0以上
