Brew doctor says Warning usr local include isn t writable

Question

Brew doctor says       Warning   usr local include isn t writable  This can happen if you  sudo make install  software that isn t managed by Homebrew       If a brew tries to write a header file to this directory  the install   will fail during the link step       You should probably chown  usr local include   I ve tried different commands to solve this but I m still stuck here   I m running homebrew on 10 8 2

sudo mkdir -p  usr local include  usr local lib  usr local sbin  sudo chown -R   whoami   usr local include  usr local lib  usr local sbin   This will create all required directories and give it the correct ownership   After running these commands check with  brew doctor  This works for Mojave

I have had this happen in my organization after all our users were bound to active directory  effectively changing the UID from 50x to           Now it is simply a case of changing the ownership of all files where were owned by x to y   Where 501 is my old numeric user id which is still associated with all the homebrew files   The old user id can be found using ll  usr local Cellar  Now update the ownership sudo find  usr local -user 501 -exec chown -h  USER        This way we avoid changing the ownership on files which are not controlled by homebrew or belong to some other system user

I just want to echo sam9046 s modest comment as an alternative and potentially much easier solution that worked in my case  uninstall and install homebrew again from scratch   No sudo commands required     You can also browse modify the uninstall script from that link above if you need to ensure it won t affect your previously installed packages   In my case this was just my home machine so I just started over

For some it s going to be    sudo chown -R JonJames admin  usr local lib   where  lib  is used as opposed to  bin  or  include  or  whatever else   The Homebrew Warning  should  explain what specifically is not writable and then give you a command syntax for follow  however you will need to use the     as opposed to what the Warning mentions which is actually not correct syntax
