-bash: /usr/local/bin/nmap: Bad CPU type in executable

Question

I recently update my Mac OS to Catalina 10.15.

I ran nmap I kept getting

-bash: /usr/local/bin/nmap: Bad CPU type in executable

I've tried reinstalling it

brew uninstall nmap
brew install nmap

but I see no effect, I even try full path

⚡️  Desktop  which nmap 
/usr/local/bin/nmap
⚡️  Desktop  /usr/local/bin/nmap
-bash: /usr/local/bin/nmap: Bad CPU type in executable
⚡️  Desktop

What's the result of file /usr/local/bin/nmap? Get the 64bit version if you detect a Mach-O executable i386. — klanomath, Jan 17 '20 at 02:47
@klanomath : I ran the command above, I got this /usr/local/bin/nmap: Mach-O 64-bit executable x86_64 — code-8, Jan 17 '20 at 02:51
If you think brew is the issue, try brew reinstall --verbose nmap and are you sure you don’t have another binary in your $PATH — bmike, Jan 17 '20 at 02:56
I install the actual .dmg from the site, seems working now. — code-8, Jan 17 '20 at 02:56
manually install rosetta helped me https://apple.stackexchange.com/questions/408375/zsh-bad-cpu-type-in-executable — dcsan, May 22 '21 at 01:03

thank you for this answer! side question: after updating to 10.15, i had issues with python and now nmap.... does anyone know why in general these issues are being caused? is 10.15 breaking almost everything for devs? – greenhouse Jun 03 '20 at 18:18
You’re welcome. Please ask and add details. – code-8 Jun 03 '20 at 18:25
Installing the latest version worked for me as well. Thanks – Suyash Jain Jun 14 '23 at 04:49

You may find this to be an x86 (32bit) vs x64 problem, thus a new version will be required.
