mac brew権限問題解決レコード

かつてはbrewがroot権限を使用して実行されていたが、現在ではroot権限がなく、brewがソフトウェアをインストールする際に権限が欠けているという問題がよく発生している.
権限の変更

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

brew doctor医師は、権限の変更による問題を診断します.

brew doctor

doctor運転後、次のように出力されます.

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: Suspicious Homebrew/brew git origin remote found.

With a non-standard origin, Homebrew won't pull updates from
the main repository. The current git origin is:
  git://mirrors.ustc.edu.cn/brew.git

Unless you have compelling reasons, consider setting the
origin remote to point at the main repository by running:
//    
  git -C "/usr/local/Homebrew" remote set-url origin https://github.com/Homebrew/brew.git

Warning: Unbrewed header files were found in /usr/local/include.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
  pkg-config

  libtool
  coreutils
  jansson
  wget
  gdbm
  imap-uw

Warning: Homebrew's sbin was not found in your PATH but you have installed
formulae that put executables in /usr/local/sbin.
Consider setting the PATH for example like so

//    ，   source ~./zshrc
  echo 'export PATH="/usr/local/sbin:$PATH"' >> ~/.zshrc

Warning: Some installed formula are missing dependencies.
You should `brew install` the missing dependencies:

//    
  brew install libidn2 libunistring

Run `brew missing` for more details.

プロンプトに従って上記の操作を完了し、実行します.
