Basic construction of Python infrastructure in Ubuntu 0 base station

This article is about Ubuntu under the Python basic Environment python2.7 (why 2.7 instead of 3?). Tornado 2.7 Support is better, and many packages are also supported 2.7)

1.

Input python found that there is no python3

Virtualenv is an environment manager for Python that isolates each environment

Pip Isntall virtualenv

　　

Virtualenv's specific use reference Liaoche's website

4. Installing the virtualenv Extension tool

sudo easy_install virtualenvwrapper

Then configure

(Specific in/usr/local/bin/virtualenvwrapper.sh there are virtualenvwrapper documents)

To create a hidden directory:

#创建隐藏目录 mkdir $HOME/.virtualenvs

Open the current directory with VI (available LS-A view). bashrc file

VI. BASHRC

#移动光标到最后一行, enter 2 lines at the end (the cursor to the last 2 lines I input does not use the VI clickable  connection)
Export Workon_home= $HOME/.virtualenvs
source/usr/local/bin/virtualenvwrapper.sh

Esc

SHIFT +: Key

Enter Wq return to exit
