cannot use prefixspan-cli

[WeiRi]

Sorry for bothering you.
Firstly I installed prefixspan by "pip3 install -U prefixspan" in Windows. The command "prefixspan-cli" can't be used in cmd, while it can be used in git bash. My python version is 3.8.3.
Then I tried to install prefixspan in Linux. But the command "prefixspan-cli" still can't be used. My system still can't recognize "prefixspan-cli" as a command. My python version here are 2.7.17 and 3.6.9.

When I uninstalled prefixspan in Linux and then install it by "pip3 install prefixspan", the command "prefixspan-cli" just works.
But when I tried this way in Windows, it still failed.
