You can use brew with sudo, but only if the brew executable is owned by root.
However, this is both not recommended and completely unsupported so do so at
your own risk.


$ sudo chown -R root /usr/local

[转]Moving From MacPorts to Homebrew

Using MacPorts? You should really think about moving to Homebrew. Why?
  • Homebrew installs packages into their own isolated prefixes and then symlinked into /usr/local.
  • It uses the libs that are already installed, no need to compile another perl, openssl or x11 and other stuff that can be found on your mac. Don’t waste time and disc space.
  • Way better command line user interface
  • Homebrew and it’s installation scripts are hosted at Github
  • The installation scripts (aka recepies) and Homebrew itself are written in ruby.
Moving from MacPorts to Homebrew sounds a little bit scary. MacPorts has tons of compiled stuff on your system. But you can do this. Trust me :) .
First, uninstall MacPorts:
sudo port -f uninstall installed
Second step: remove everything that is left from MacPorts (check for MySQL and other stuff in /opt/local first) :
sudo rm -rf /opt/local
sudo rm -rf /Applications/DarwinPorts
sudo rm -rf /Applications/MacPorts
sudo rm -rf /Library/LaunchDaemons/org.macports.*
sudo rm -rf /Library/Receipts/DarwinPorts*.pkg
sudo rm -rf /Library/Receipts/MacPorts*.pkg
sudo rm -rf /Library/StartupItems/DarwinPortsStartup
sudo rm -rf /Library/Tcl/darwinports1.0
sudo rm -rf /Library/Tcl/macports1.0
sudo rm -rf ~/.macports
Alternatively you can move those directories to another place and delete them if everything is okay (if you don’t trust your Timemachine ;) ).
After that you should remove the /opt/local/bin from your $PATH.
Now install Homebrew with the command you find here.
