我已经安装了gps软件包和mysql软件包： 安装apt sugpsd客户端 sudo dpkg重新配置gpsd &安培； sudo apt get install python2.7-mysqldb 它显示包已经成功安装，但是当我运行python代码时，它有：

import gps 
import MySQLdb as mdb
error comes:
ImportError: No module named gps
and ImportError: No module named MySQLdb
in python sys.path gives the following:
sys.path
['', '/home/odroid/.virtualenvs/barc/src/django-tastypie-master', '/home/odroid/barc/workspace/devel/lib/python2.7/dist-packages', '/opt/ros/indigo/lib/python2.7/dist-packages', '/usr/local/lib/python2.7/site-packages', '/home/odroid/.virtualenvs/barc/lib/python2.7', '/home/odroid/.virtualenvs/barc/lib/python2.7/plat-arm-linux-gnueabihf', '/home/odroid/.virtualenvs/barc/lib/python2.7/lib-tk', '/home/odroid/.virtualenvs/barc/lib/python2.7/lib-old', '/home/odroid/.virtualenvs/barc/lib/python2.7/lib-dynload', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-arm-linux-gnueabihf', '/usr/lib/python2.7/lib-tk', '/home/odroid/.virtualenvs/barc/local/lib/python2.7/site-packages', '/home/odroid/.virtualenvs/barc/lib/python2.7/site-packages']

%已解决，如果python在虚拟环境中运行，则模块的路径存在问题。需要更改路径：

export PYTHONPATH=$PYTHONPATH:/usr/lib/python2.7/dist-packages%每次关闭终端窗口时都必须执行此命令 以及永久性地实施这种改变// 来源：vim.bashrc %copy//export PYTHONPATH=$PYTHONPATH:/usr/lib/python2.7/dist-packages %然后呢 来源：bashrc
