Can't return outside a subroutine at ./LabelMe/annotationTools/perl/fetch_image.cgi

Ubuntu 16.04 LTS. Install went ok, all apache mods required have been enabled. Image appears on page load, but then the page returns an error: Fatal: there are problems with fetch_image.cgi

Apache logs show the following:

[Thu Jun 07 13:07:41.886343 2018] [cgi:error] [pid 1427] [client 127.0.0.1:44032] AH01215: [Thu Jun 7 13:07:41 2018] fetch_image.cgi: Can't return outside a subroutine at LabelMe/annotationTools/perl/fetch_image.cgi line 49.: LabelMe/annotationTools/perl/fetch_image.cgi, referer: https://localhost/LabelMe/tool.html?collection=Shoes&mode=i&folder=Shoes&image=image.jpg

I've installed libcgi-session-perl and restarted Apache, but that didn't do much of anything.

Any other suggestions?

从第 49 行的 LabelMe/annotationTools/perl/fetch_image.cgi 开始，将报告的 Apache CGI 错误与脚本周围的上下文进行比较。检查已安装的 CGI 依赖项和 Apache 配置是否会影响执行。当图像页面加载时不再出现 fetch_image.cgi 致命错误，并且 Apache 日志不再报告 return-outside-subroutine 故障，即表示完成。
