Flask学习笔记 -- 1

开发环境的搭建：

1. Sublime Text 3
   
2. pip
   
3. virtualenv
   
4. flask

1 安装Sublime Text 3

Ubuntu中没有python编辑器，Sublime Text 就挺好用的。

for-python@ubuntu:~$ sudo add-apt-repository ppa:webupd8team/sublime-text-3for-python@ubuntu:~$ sudo apt-get updatefor-python@ubuntu:~$ sudo apt-get install sublime-text-installerfor-python@ubuntu:~$ subl  #打开sublime text

2 安装pip

for-python@ubuntu:~$ sudo apt-get install python3-pip

创建虚拟环境时会安装pip setuptools 等，（这里安装pip3好像暂时用不到）。

for-python@ubuntu:~$ virtualenv learn-flaskUsing base prefix '/usr'New python executable in /home/for-python/learn-flask/bin/python3Also creating executable in /home/for-python/learn-flask/bin/pythonInstalling setuptools, pip, wheel...done.

3 安装virtualenv

for-python@ubuntu:~$ sudo apt-get install python-virtualenv

4 虚拟环境

for-python@ubuntu:~$ virtualenv learn-flask  #创建虚拟环境for-python@ubuntu:~$ source learn-flask/bin/activate  #激活(learn-flask) for-python@ubuntu:~$ pip install flask #虚拟环境中安装flask(learn-flask) for-python@ubuntu:~$ pip install flask-script

然后，虚拟环境中安装好了flask:

(learn-flask) for-python@ubuntu:~$ pythonPython 3.5.3 (default, Jan 19 2017, 14:11:04) [GCC 6.3.0 20170118] on linuxType "help", "copyright", "credits" or "license" for more information.>>> import flask>>> quit()

5 退出虚拟环境

(learn-flask) for-python@ubuntu:~$ deactivate

虚拟环境外面使用 import flask ，发现没有安装flask。
（Linux 默认python2，指定python3可以运行python3）
