Dealing with PermissionError [Error 1] for pip install -U pip on macOS Sierra

Overview

Mac book Air (late2013) Install python3 environment with anaconda As a beginner, 2.7 environment is not required It's been a while since I tried to install a package with pip I was told to update pip itself.

command

Normally # pip install -U pip If so, will it work? It ends with an error. In the terminal PermissonError: [Error 1] Operation not permitted: '/bin/pip' Is displayed and it does not work.

As a result of investigating for about 3 hours

At the time of El Capitan, I was stuck in the Homebrew area one after another I tried to add Atari when it was related to SIP.

In homebrew, enter the permissions of / usr / local into recovery mode (⌘ + R at startup) and turn off SIP

#csrutil disable

Reboot

chown -R $ (whoami): admin / usr / local Permission change

Enter recovery mode again

#csrutil enable

It ended with, but this time it's Python pip, so it's under / bin, so after cutting SIP as well

chown -R $(whoami):admin /bin

I tried to run it as.

# pip install -U pip

I still got the same error, so I tried it with the following command.

#pip install --user -U pip

I was able to update without any errors.

Maybe

Maybe you didn't need to change the permissions of / bin just by specifying --user in the pip option?
