How can I get nasm to work as a command in terminal in MacOS?

问题

I have been trying to get nasm to work as a command in terminal, but nothing seems to be working. I just keep getting the error:

nasm: error: unable to find utility "nasm", not a developer tool or in PATH

So, first, I tried updating my PATH variable. I tried editing the PATH variable:

safecrackers-MacBook-Pro-2:Library safecracker$ export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Library/Libraries/nasm-2.14/
safecrackers-MacBook-Pro-2:Library safecracker$ nasm
nasm: error: unable to find utility "nasm", not a developer tool or in PATH
safecrackers-MacBook-Pro-2:Library safecracker$ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Library/Libraries/nasm-2.14/
safecrackers-MacBook-Pro-2:Library safecracker$ cd /Library/Libraries/nasm-2.14/
safecrackers-MacBook-Pro-2:nasm-2.14 safecracker$ ls
LICENSE     man1        ndisasm     rdf2ihx     rdfdump
README      nasm        rdf2bin     rdf2ith     rdflib
ldrdf       nasmdoc.pdf rdf2com     rdf2srec    rdx

I got the same error. Next, I tried installing nasm with homebrew:

safecrackers-MacBook-Pro-2:~ safecracker$ brew reinstall nasm

nasm: error: unable to find utility "nasm", not a developer tool or in PATH

Again, I got the same error. I would love to finally figure this out.

回答1:

To avoid /usr/bin/nasm be found first in PATH use

$ /usr/local/bin/nasm

to find the one installed by brew, or

alias nasm=/usr/local/bin/nasm

and then

$ nasm

回答2:

I have solved this problem by:

brew reinstall nasm

回答3:

I solved the issue with

sudo chown -R "your_username_folder" /usr/local/share/man/man8 

On terminal

My brew was not configured properly, after this command and

brew install nasm

My NASM command is working properly
