If you are using OSX High Sierra chown operation is not permitted in /usr/local/ in this case use:

sudo chown -R $(whoami) /usr/local/Homebrew/

MacOS – Issue installing GCC using homebrew (scipy package dependency)

It's caused by your new OS X Yosemite, try the following command to install gcc on Yosemite

    brew install https://raw.githubusercontent.com/denji/homebrew/gcc/Library/Formula/gcc.rb

MacOS – Trying to install Homebrew, but I get this “fatal: cannot create directory at ‘Library/ENV/pkgconfig/10.10’: Permission denied”

I would suggest go and visit 'Library/ENV/pkgconfig/10.10', if it's there, try to look at its permission, if it differs, try to delete it and re-run the installation.

It happen to me once also but it's coming from sass/grunt. Permission denied just to find out that special file was created by other user (because I copied it from somewhere) and it have overriding problems, thats why it return permission denied.

Well, that's my case, hope this little stuff might help you. Who knows :P
