在本地安裝pyenv的時候，出現瞭如下的報錯：

➜   brew install pyenv
==> Downloading https://github.com/yyuu/pyenv/archive/v20160310.tar.gz
Already downloaded: /Library/Caches/Homebrew/pyenv-20160310.tar.gz
Error: parent directory is world writable but not sticky

/usr/local/Library/brew.rb:83:in `<main>'

解決方法：
先檢視自己本機 /private/tmp 的資料夾的讀寫許可權,在我的mac機器上如下：

➜  ls -ld /tmp
lrwxr-xr-x@ 1 root  wheel  11 11 13  2014 /tmp -> private/tmp
➜  ls -ld /private/tmp
drwxrwxrwt  13 root  wheel  442  1 18 09:07 /private/tmp

為了解決這個 'sticky' permission of /private/tmp ,需要執行如下的命令：
sudo chmod +t /private/tmp/

執行完之後，再安裝就成功了：

➜  brew install pyenv
==> Downloading https://github.com/yyuu/pyenv/archive/v20160310.tar.gz
Already downloaded: /Library/Caches/Homebrew/pyenv-20160310.tar.gz
==> Caveats
To use Homebrew's directories rather than ~/.pyenv add to your profile:
  export PYENV_ROOT=/usr/local/var/pyenv

To enable shims and autocompletion add to your profile:
  if which pyenv > /dev/null; then eval "$(pyenv init -)"; fi
==> Summary
?  /usr/local/Cellar/pyenv/20160310: 469 files, 2M, built in 0 seconds
