参考：
去用：
记得先进入虚拟环境中：
workon SIPEvents
然后再去：
(SIPEvents) ➜ SIPEvents pip freeze > requirements.txt (SIPEvents) ➜ SIPEvents cat requirements.txt click==6.6 Flask==0.11.1 gunicorn==19.6.0 itsdangerous==0.24 Jinja2==2.8 MarkupSafe==0.23 pycrypto==2.6.1 requests==2.6.0 six==1.10.0 uWSGI==2.0.13.1 wechat-sdk==0.6.4 Werkzeug==0.11.10 xmltodict==0.10.2 |
以便于以后去，重新安装和部署环境。
然后以后有空再去：
为生产运行环境 和 开发环境，分别创建对应的：
require_run.txt和require_dev.txt
［后记］
折腾了一段时间，再次去导出依赖的包：
进入虚拟环境：
➜ SIPEvents workon SIPEvents ll (SIPEvents) ➜ SIPEvents ll total 44K -rw-r–r– 1 root root 436 Aug 25 16:47 config.py -rw-r–r– 1 root root 186 Aug 25 16:48 config.pyc -rw-r–r– 1 root root 6.8K Aug 30 17:53 db_create.py -rw-r–r– 1 root root 773 Aug 29 17:57 db_manager.py drwxr-xr-x 2 root root 4.0K Sep 2 15:27 instance -rw-r–r– 1 root root 204 Aug 22 11:41 requirements.txt -rw-r–r– 1 root root 77 Aug 23 14:39 run.py -rw-r–r– 1 root root 266 Aug 23 15:43 run.pyc drwxr-xr-x 4 root root 4.0K Sep 1 21:57 sipevents drwxr-xr-x 2 root root 4.0K Aug 21 11:04 toDel |
看看pip的freeze的命令的功能：
(SIPEvents) ➜ SIPEvents pip help Usage: pip <command> [options] Commands: install Install packages. download Download packages. uninstall Uninstall packages. freeze Output installed packages in requirements format. list List installed packages. show Show information about installed packages. search Search PyPI for packages. wheel Build wheels from your requirements. hash Compute hashes of package archives. completion A helper command used for command completion help Show help for commands.

Implied with –no-index. |
再去执行：
(SIPEvents) ➜ SIPEvents pip freeze > requirements.txt (SIPEvents) ➜ SIPEvents cat requirements.txt alembic==0.8.7 click==6.6 enum34==1.1.6 Flask==0.11.1 Flask-Images==2.1.2 Flask-Login==0.3.2 Flask-Migrate==2.0.0 Flask-Script==2.0.5 Flask-SQLAlchemy==2.1 gunicorn==19.6.0 itsdangerous==0.24 Jinja2==2.8 Mako==1.0.4 MarkupSafe==0.23 PIL==1.1.7 Pillow==3.3.1 pillowcase==2.0.0 pycrypto==2.6.1 python-editor==1.0.1 requests==2.6.0 six==1.10.0 SQLAlchemy==1.1.0b3 uWSGI==2.0.13.1 wechat-sdk==0.6.4 Werkzeug==0.11.10 xmltodict==0.10.2 |
