python创建Django项目Couldn't import Django解决思路

最近学习Django，首先就是搭建环境

1起初就是安装过python，版本为2.7

2安装Django，正在python中测试版本成功如下：

Python 2.7.10 (default, Jul 30 2016, 19:40:32)
[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.34)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>> django.VERSION
(1, 11, 2, u'final', 0)
>>>
3 继续创建Django项目，项目名为first

 django-admin.py startproject project first

4接着用pycharm打开，给runserver作出配置

5点击运行first项目，遇到import错误（着重敲黑板）如下：

try:    import djangoexcept ImportError:    raise ImportError(        "Couldn't import Django. Are you sure it's installed and "        "available on your PYTHONPATH environment variable? Did you "        "forget to activate a virtual environment?"    )raise

这时，我开始查资料，各种百度，没看见什么有效的解决办法。。。

解决思路：

(1)python版本的问题，因为编译器自带了python2.6，尝试换了自己安装的版本

(2)点击运行，又报错，是script parameter的错误（和谐：百度不可靠），发现这个参数原来是如下：

[auth]
    changepassword
    createsuperuser

[contenttypes]
    remove_stale_contenttypes

[django]
    check
    compilemessages
    createcachetable
    dbshell
    diffsettings
    dumpdata
    flush
    inspectdb
    loaddata
    makemessages
    makemigrations
    migrate
    sendtestemail
    shell
    showmigrations
    sqlflush
    sqlmigrate
    sqlsequencereset
    squashmigrations
    startapp
    startproject
    test
    testserver

[sessions]
    clearsessions

[staticfiles]
    collectstatic
    findstatic
    runserver

结合百度，果断选择runserver.

(3)最后运行结果如下：

System check identified no issues (0 silenced).

You have 13 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.
Run 'python manage.py migrate' to apply them.

Django version 1.11.2, using settings 'project.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

执行成功
