先说结论：以后在涉及到定时任务，指定python的环境路径。
shell中python路径问题
定时任务默认的python路径为系统自带
写一个python程序sys_path.py
import sys
print(sys.path)
放入shell脚本sys_path.sh
python ./sys_path.py
执行sh脚本
sh sys_path.sh
['/data0/qinyk/test', '/data0/anaconda3/lib/python36.zip', '/data0/anaconda3/lib/python3.6',
'/data0/anaconda3/lib/python3.6/lib-dynload',
'/data0/anaconda3/lib/python3.6/site-packages',
'/data0/anaconda3/lib/python3.6/site-packages/PyHive-0.3.0-py3.6.egg',
'/data0/anaconda3/lib/python3.6/site-packages/xgboost-0.71-py3.6.egg']
定时任务crontab -e 并保存日志
* * * * * sh sys_path.sh >sys_path.log 2>&1
cat sys_path.log
['/data0/qinyk/test', '/usr/lib64/python26.zip', '/usr/lib64/python2.6',
'/usr/lib64/python2.6/plat-linux2', '/usr/lib64/python2.6/lib-tk', '/usr/lib64/python2.6/lib-old',
'/usr/lib64/python2.6/lib-dynload', '/usr/lib64/python2.6/site-packages',
'/usr/lib64/python2.6/site-packages/gtk-2.0', '/usr/lib/python2.6/site-packages']
