假设您的 LD_LIBRARY_PATH = $ LD_LIBRARY_PATH：/ usr / local / lib 工作正常，您可以在crontab文件顶部设置环境变量，如下所示

Assuming your LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib expression is working fine, you can set up environment variables at the top of the crontab file like below

#Setting up Environment variables
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

#Here follow the cron jobs
* * * * *   echo $LD_LIBRARY_PATH >> /home/user/logfile.log
* * * * *   some/cron/job.py
