crontab importerror:no module named XXX occurs when calling Python

In the http://chenx1242.blog.51cto.com/10430133/1884415 wrote a monitoring MQ script, the script into the crontab to monitor the time, so #crontab- e, To add a statement:

* * * * * CD/directory && python MQ script name. PY >/root/mq.log 2>&1

Send the results of the execution to the/root/mq.log, and open a look inside to see that the error has occurred:

But in the shell alone execution is OK, so add source/etc/profile or error, visible is not the problem of environment variables, how to do?

First,#which pythonto determine the path to Python:

The entire Python path is copied into the crontab, the whole #crontab-l effect is like this:

* * * * * * source/etc/profile && CD/directory && nohup/usr/local/bin/python MQ script name. PY >/root/mq.log 2>& ; 1

If more than one version of Python is installed on a machine, it is more about specifying the path to Python, or crontab will be foolish enough to find the default path.
