当我尝试做任何事情时Homebrew,我收到以下错误,不知道如何解决它.我跑:brew update

我收到以下错误消息:

/usr/local/Homebrew/Library/Homebrew/utils/lock.sh: line 19:/usr/local/var/homebrew/locks/update: Permission denied
    -e:1:in 'initialize': Bad file descriptor (Errno::EBADF)
        from -e:1:in 'new'
        from -e:1:in '<main>'
    Error: Another active Homebrew process is already in progress. 
    Please wait for it to finish or terminate it to continue.

如何隐藏Sublime Text 3右侧的大型垂直滚动条？当前(默认)滚动条显示文档的预览,我想将其删除.这可能吗？

Sublime Text版本3,macOS Sierra.
