Where does homebrew log

homebrew

Does homebrew keep logs, and if so where?

I did a brew update which broke python support in macvim, and now I can't even get macvim to build. I'm hoping that there are some clues in the log.

~/Library/Logs/Homebrew/

Homebrew creates log files in your Library folder at: ~/Library/Logs/Homebrew/

You can view the log files by holding down Option and using the Finder menu item: Go > Library, then navigating to Logs > Homebrew.

Alternatively, you can use the Console.app application to browse to the log files.

Homebrew History

The default creation of individual log files was added during 2013 to Homebrew.

Homebrew issue #10430 talks about logging and build errors. The issue report mentions no log file is kept but explains that a log can be created with the command format:

brew install <formula> 2>&1 | tee install.log

Can’t re-install homebrew

Short term answer, try this command to see if your brew installation worked:

/usr/local/bin/brew doctor

It seems that your bash environment may not be looking in the /usr/local/bin for executibles (which means you have to write the full path rather than just the name of the command). The solution may be just resourcing your conf files, which can be roughly done by closing your terminal and opening a new one. Otherwise, you'll want to add a line to your ~/.bash_profile. I think resourcing will do the trick though.

So after confirming the success with the first doctor, try quitting your terminal application and starting fresh, then your original usage of brew should work. If it doesn't try:

echo $PATH

and report back the results.

Homebrew libgfortran

It should be installed and linked from the gcc formula:

~ » readlink `which gfortran`                                                                                      
../Cellar/gcc/5.1.0/bin/gfortran
