ubuntu18启动python_ubuntu-18.04 设置开机启动python脚本

分析

1)在本地进入python交互环境，查看python搜索路径code nvidia@nvidia-desktop:~/data/projects/dt_product$ python

Python 2.7.15+ (default, Nov 27 2018, 23:36:35)

[GCC 7.3.0] on linux2

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

>>> import sys

>>> sys.path

['', '/home/nvidia/.local/lib/python2.7/site-packages', '/home/nvidia/data/projects/dt_product', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-aarch64-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', '/usr/lib/python2.7/dist-packages/gtk-2.0']

>>>

2)新建一个python脚本设置为开机启动，在此脚本中获取python搜索路径orm !test.py

import sys

print sys.path

从新启动环境查看启动重定向得日志 log.txt ： ['/home/nvidia/data/projects/dt_product', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-aarch64-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', '/usr/lib/python2.7/dist-packages/gtk-2.0']

对比发现少了一个路径：'/home/nvidia/.local/lib/python2.7/site-packages',环境上看此路径为没法import 包得安装路径；应该是安装这些包时留的坑。
