最近把自己在windows上的Django项目放在的Ubuntu上，启动时提示找不到模块

原来是自己的项目用的是虚拟环境，安装的第三方库全部在虚拟环境中 AutoTestSite/venv/Lib/site-packages

在Ubuntu中查看模块搜索路径：

chen@ubuntu:~$ python

Python 2.7. (default, Nov  , ::)

[GCC 5.4. ] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> import sys

>>> sys.path

['', '/home/chen', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages']

发现并没有这个路径：AutoTestSite/venv/Lib/site-packages

所以需要添加路径：

编辑文件 sudo vi .bashrc ，在最下方添加：

export PYTHONPATH="/home/**/**/venv/Lib/site-packages:$PYTHONPATH"

chen@ubuntu:~$ sudo vi .bashrc 

# ~/.bashrc: executed by bash() for non-login shells.

# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)

# for examples

# If not running interactively, don't do anything

case $- in

    *i*) ;;

      *) return;;

esac

# don't put duplicate lines or lines starting with space in the history.

# See bash() for more options

HISTCONTROL=ignoreboth

# append to the history file, don't overwrite it

shopt -s histappend

# for setting history length see HISTSIZE and HISTFILESIZE in bash()

HISTSIZE=

HISTFILESIZE=

# check the window size after each command and, if necessary,

# update the values of LINES and COLUMNS.

shopt -s checkwinsize

# If set, the pattern "**" used in a pathname expansion context will

# match all files and zero or more directories and subdirectories.

#shopt -s globstar

# add python project autotestsite module search path assress

export PYTHONPATH="/home/guchen/python/www/for_test/AutoTestSite/venv/Lib/site-packages:$PYTHONPATH"

执行：source .bashrc

使修改生效

再次查看sys.path,已经添加了

chen@ubuntu:~$ python

Python 2.7. (default, Nov  , ::)

[GCC 5.4. ] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> import sys

>>> sys.path

['', '/home/chen/python/www/AutoTestSite/venv/Lib/site-packages', '/home/chen', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages']
