Since I need to use the plantri package in my research. I tried to install it in sagemath 9.3 in windows version. sage: !sage -i plantri  But the installation process always reminds: make build/make/Makefile --stop make[3862]: Entering directory '/opt/sagemath-9.3' make[3862]: *** [Makefile:37: bootstrap] Error 127  I don't know what the reason is. I personally think that planri and nauty have different focuses, but they are equally good. So my suggestion is whether it is possible to have plantri built in like nauty in future versions. It's disappointing that the installation always fails.
