homebrew -v 或homebrew -doctor报错请检查 .bash_profile是否有误

homebrew -doctor报错：

/usr/local/Library/Homebrew/global.rb:109:in `split': invalid byte sequence in UTF-8 (ArgumentError)
from /usr/local/Library/Homebrew/global.rb:109:in `<top (required)>'
from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'

检查echo $PATH 是否有？等非正常字符

如果有，请将PATH修改或者最简化写，就不会出错：

export PATH=/usr/local/bin:/Users/Martin/.rvm/gems/ruby-2.1.2/bin:/Users/Martin/.rvm/gems/ruby-2.1.2@global/bin:/Users/Martin/.rvm/rubies/ruby-2.1.2/bin:/opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Users/Martin/.rvm/bin
