从cronjob中的脚本启动phantomJS

Question

我正在通过cronjob运行python脚本.我有一个虚拟环境,在cronjob中,我正在通过这个虚拟环境运行它.当我运行脚本时,通常phantomJS应该启动它,但是通过cronjob中的脚本运行它我得到了这个错误.cronjob中缺少什么才能启动phantomjs？

Message: 'Unable to start phantomjs with ghostdriver.' ; Screenshot: available via screen

由于可能安装了幻像/usr/local/bin,您应该PATH在crontab中添加该dir .以下应该做的伎俩:

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
