install django采坑

1. install python 3

2. install pip

3.  install virtual enviroment : python -m venv myvenv

4. 切换到virtualEnv ：

[root@zhuvm13662 djangogirls]# source myvenv/bin/activate

5. intall django

(myvenv) ~$ pip install django==1.8.2

6. 新建一个项目 (myvenv) [root@zhuvm13662 djangogirls]# django-admin.py startproject mysite，检查一下 mysite 文件夹， 然后 配置 settings,

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}
7. 切换到mysite 目录，执行

(myvenv) [root@zhuvm13662 mysite]# python manage.py runserver

错误1 :

No module named _sqlite3

解决方法： yum -y install sqlite-devel, 然后 切换到python 安装目录， cd  Python-3.6.5, 执行 ./configure, ,make ,make install. 重新编译并且安装，问题解决

(myvenv) [root@zhuvm13662 mysite]# python manage.py runserver
