CMD on Mac Catalina

[fairport]

Today I tried to use cmd6.7.0.63
on Mac Catalina 10.15 (19A583) . (It worked yesterday? Maybe my Mac auto updated something overnight)

I am getting this error msg:
Sencha Cmd v6.7.0.63
java.io.IOException: Cannot run program "npm": error=2, No such file or directory


I tried installing CMD 7 .. But the Mac refuses to install it.
“SenchaCmd-7.0.0.40-osx” can’t be opened because Apple cannot check it for malicious software.

So... I am fully snookered
Any ideas
Thx

Sorry for the alarm.. !
Unlike previous installs of applications that Mac is uncertain about, this install didn't ask me to allow it to install "anyway".

However, I later went to System Preferences & there WAS in fact an option to "Install Anyway"... So.. with that done, it installed OK & built my app as well !!

Just as a temporary solution, instead of `double clicking` to install the package. You could also `right-click` it and then click `Open`.
That forces the installation as well.
