最近把自己在windows上的Django專案放在的Ubuntu上，啟動時提示找不到模組

原來是自己的專案用的是虛擬環境，安裝的第三方庫全部在虛擬環境中 AutoTestSite/venv/Lib/site-packages

在Ubuntu中檢視模組搜尋路徑：

[email protected]:~$ python
Python 2.7.12 (default, Nov 12 2018, 14:36:49) 
[GCC 5.4.0 20160609] 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']

發現並沒有這個路徑：AutoTestSite/venv/Lib/site-packages

所以需要新增路徑：

編輯檔案 sudo vi .bashrc ，在最下方新增：

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

[email protected]:~$ sudo vi .bashrc 

# ~/.bashrc: executed by bash(1) 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(1) 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(1)
HISTSIZE=1000
HISTFILESIZE=2000

# 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"

執行：source .bashrc

使修改生效

再次檢視sys.path,已經添加了
