首次自制安装失败

Question

我刚刚被介绍给Rails，并按照指示安装"homebrew“(使用Mac 10.11.3)。我试着通过复制粘贴安装代码行的方式安装Homebrew，但是不知怎么的，我收到了一条“失败的”消息(这是我第一次尝试安装)。

我不知道，所以我再次输入了代码行，下面是出现的情况(第二次，我得到了“文件存在”和“失败期间”)：

 ==> Downloading and installing Homebrew...
remote: Counting objects: 54, done.
remote: Compressing objects: 100% (20/20), done.
remote: Total 54 (delta 45), reused 40 (delta 33), pack-reused 0
Unpacking objects: 100% (54/54), done.
error: cannot lock ref 'refs/remotes/origin/master': Unable to 
create '/usr/local/Homebrew/.git/refs/remotes/origin/master.lock':
File exists.

If no other git process is currently running, this probably means a
git process crashed in this repository earlier. Make sure no other git
process is running and remove the file manually to continue.
From https://github.com/Homebrew/brew
! [new branch]      master     -> origin/master  (unable to update
local ref)
Failed during: git fetch origin master:refs/remotes/origin/master --
tags --force --depth=1

我对发展完全陌生，不知道该怎么做。有人有小费吗？

Answer 1

删除此文件

/usr/local/Homebrew/.git/refs/remotes/origin/master.lock

试一试

rm -f /usr/local/Homebrew/.git/refs/remotes/origin/master.lock

然后再试
