我正在尝试通过 EC2 上的 crontab 运行 Python 脚本（它是网络抓取）。但它不起作用。
这是我的任务：
SHELL = /bin/bash
PATH = /usr/local/sbin:/usr/local / bin: / sbin: / bin: / usr / sbin: / usr / bin
* * / 2 * * * / usr / bin / python /home/ec2-user/LATAM_v1.py
我收到来自系统的电子邮件，说未安装 pandas。
但它已安装。
我还直接在 shell 中运行脚本：
/home/ec2-user/LATAM_v1.py
/ usr / bin / python home / ec2-user / LATAM_v1.py
两种方法都奏效了。
如果它们正在运行，我已经检查了 cron 和守护程序的状态，它们是。
这是错误：

This is the version of the machine:
NAME = "Amazon Linux AMI"
VERSION = "2018.03"
ID = "amzn"
ID_LIKE = "rhel fedora"
PRETTY_NAME = "Amazon Linux AMI 2018.03"
我已经审查了 Stackoverflow，我得到了很多答案等等，但这里没有任何效果。
我对Linux不熟悉。如果有人知道如何解决它并逐步解释它，我将不胜感激。
非常感谢。
