can't locate open.pm in @inc (you may need to install the open module)

本来就是火焰图不熟悉，perl的bug更是火上浇油

报错：
$ ./flamegraph.pl perf.folded > perf.svg
Can't locate open.pm in @INC (you may need to install the open module) (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at ./flamegraph.pl line 97.
BEGIN failed--compilation aborted at ./flamegraph.pl line 97.

解决办法：

更新perl版本：yum install perl

可能安装上了这个：

perl-open noarch 1.11-416.el8 AppStream 77 k
