How to get root rights in the /usr/bin folder?

Question

macOS

I execute the command
sudo cp ~/.meteor/meteor /usr/bin/meteor
,
cp: /usr/bin/meteor: Operation not permitted
I can't copy the file with my hands into the folder from finder. What to do?

Answer 1

Answer: open terminal on reboot and type:

csrutil disable
reboot

Answer 2

Do you have permission to execute this command in sudo? sudo is a program that is strictly related to security to the point of insanity - you write /usr/bin/zhopa, and you type sudo zhopa - you will get a drum on your neck :)

Answer 3

after sudo ~/.meteor/meteor is looked for in /var/root, not in your home directory.
specify the full path
sudo cp /Users/XXX/.meteor/meteor /usr/bin/meteor
