使用pyinstaller打包django

虽然django项目我们一般通过部署服务器进行发布，但是也有些情况，可能就是一个小小的数据管理应用，也就内部几个人使用，想直接打包成一个应用，在没有任何python环境的普通的机器上就能运行，内网能访问就可以了。
pyinstaller 就能够用来将python应用打包成可执行文件。

Step 1: 生成spec文件

pyi-makespec -D manage.py 

执行成功后，会显示如下信息，表示可以去构建可执行文件了

now run pyinstaller.py to build the executable

在目录下面会生成一个 manage.spec的文件，相当于一个构建可执行文件的配置文件。打开文件，可以看一下，主要有两个地方需要配置：
1.datas=[] 该配置用于配置static文件和templates文件
hiddenimports=[] 把settings里的install_apps 拷贝过来

 datas=[('/Users/huanghuan/Documents/python学习/django/loftyha/static','./static')],
             hiddenimports=[ 'django.contrib.admin',
                    'django.contrib.auth',
                    'django.contrib.contenttypes',
                    'django.contrib.sessions',
                    'django.contrib.messages',
                    'django.contrib.staticfiles',
                    'shift',],

Step 2: 使用pyinstaller 构建可执行文件

pyinstaller manage.spec 

待上述命令执行完，在目录下面会生成dist和build目录，在dist/manage目录下，有一个可执行文件manage
cd dist/manage目录下，命令行执行manage文件

./manage runserver ip:port --noreload

--noreload参数如果不加，有可能会报错: RuntimeError('Script %s does not exist.' % py_script)
