Impossibile aggiornare brew in MAC OS X el capitan e continuare a ricevere un errore di carico con `require`

Question

Non sono sicuro del motivo per cui ciò sta accadendo, ma non riesco ad aggiornare brew nel mio MAC OS X El Capitan. Ho fatto:

brew update

ed ho ottenuto:

warning: unable to unlink CONTRIBUTING.md: Permission denied 
warning: unable to unlink SUPPORTERS.md: Permission denied 
fatal: cannot create directory at '.github': Permission denied 

di andare oltre tale questione ho sudoed il comando precedente, ma ottenuto ulteriori problemi:

sudo brew update

    from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'

    from /usr/local/Library/brew.rb:16:in `<main>' 

ora ogni volta che faccio birra installo Ottengo:

brew update

    from /usr/local/Library/brew.rb:16:in `<main>' 

infatti, sembra che ogni volta che faccio qualcosa, tipo solo digitare brew, si ottiene lo stesso messaggio. Qualcuno sa come risolvere questo problema?

Answer 1

Non utilizzare sudo con Homebrew. In primo luogo eseguire il seguente per essere sicuri di proprietario tutto sotto /usr/local:

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

quindi reimpostare il tuo repo Homebrew ad uno stato pulito:

cd /usr/local && git fetch && git reset --hard origin/master 

Si dovrebbe risolvere i vostri problemi.

(sostituire /usr/local con $(brew --prefix) se è stata installata Homebrew altrove)
