After installing Yosemite, I was unable to run brew or ruby.

This error can easily be fixed in the following steps:

可以通过以下步骤轻松修复此错误：

1) Open terminal

1) 打开终端

2) Type nano /usr/local/Library/brew.rb

2) 类型 nano /usr/local/Library/brew.rb

3) In the first line change “1.8″ to “Current”, so it should look like this:

3) 在第一行中将“1.8”改为“Current”，所以它应该是这样的：

#!/System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby -W0

I updated to Yosemite and later found out brewwas broken.

我更新到优胜美地，后来发现brew坏了。

/usr/local/bin/brew: /usr/local/Library/brew.rb: 
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby: bad interpreter: No such file or directory /usr/local/bin/brew: line 23: /usr/local/Library/brew.rb: Undefined error: 0

If you haven't made any changes to brew yet, here is what I recommend. Otherwise read further below.

如果您还没有对 brew 进行任何更改，那么这就是我的建议。否则请阅读下文。

  1. cd /System/Library/Frameworks/Ruby.framework/Versions/
  2. sudo ln -s Current 1.8
  3. brew update
  4. sudo unlink 1.8
  1. cd /System/Library/Frameworks/Ruby.framework/Versions/
  2. sudo ln -s Current 1.8
  3. brew update
  4. sudo unlink 1.8

Already made changes to brew files and stuck in a git mess?

已经对 brew 文件进行了更改并陷入了 git 混乱？

I tried to edit /usr/local/Library/brew.rbbut the local change to my git repo was preventing brew updatefrom pulling down updates. I tried some other solutions mentioned on this page and from other sites and I ended up with a git mess and all I wanted to do was undo everything I had done to brew.

我尝试编辑，/usr/local/Library/brew.rb但对我的 git 存储库的本地更改阻止brew update了更新。我尝试了本页面和其他网站上提到的其他一些解决方案，但最终还是搞砸了，我想做的就是撤消我为 brew 所做的一切。

I committed my change but it made things worse. Eventually I had to undo my commits and git reset --hard HEAD~1until I was at the right commit-ish. I had a mess of unversioned files too (I changed files permissions in /usr/Local) so I did a git clean -f -dwhich removed all unversioned files and directories and got me back to where I started before I made any changes.

我做出了改变，但这让事情变得更糟。最终我不得不撤消我的提交，git reset --hard HEAD~1直到我处于正确的提交状态。我也有一堆未版本化的文件（我更改了 /usr/Local 中的文件权限），所以我git clean -f -d删除了所有未版本化的文件和目录，并在进行任何更改之前让我回到了开始的位置。

Steps to fix it:

修复它的步骤：

  1. Install command line tools for Xcode 6

  2. Reinstall brew:

    ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

  3. Once brew is installed, rvm will work:

    rvm install ruby

  1. 为 Xcode 6 安装命令行工具

  2. 重新安装酿造：

    ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

  3. 安装 brew 后，rvm 将工作：

    rvm install ruby

Worked for me, yahoo!

对我来说有效，雅虎！

Editing the script means brew updatewon't work; there are local edits to tracked files which causes the git pullto fail.

编辑脚本意味着brew update不起作用；对跟踪文件进行了本地编辑，导致git pull失败。

I did this, which I suspect is cleaner:

我这样做了，我怀疑它更干净：

cd /usr/local/Library
git pull -q origin refs/heads/master:refs/remotes/origin/master

There are no complaints from brew doctor.

没有来自 的投诉brew doctor。

This is a conglomeration from answers from other people's posts as well as a bit of digging on Google, but I figured I'd put it up so a complete answer is in one place. Specifically this gets things to work now, but also lets you do brew updates as normal and gets everything clean again.

这是来自其他人帖子的答案以及对谷歌的一些挖掘的集合，但我想我会把它放在一个地方，所以完整的答案是在一个地方。具体来说，这可以让事情现在开始工作，但也可以让您像往常一样进行 brew 更新并再次使一切变得干净。

  1. Open /usr/local/Library/brew.rb (emacs/vi/nano/whatever)
  2. Change the first line to read: #!/System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby -W0. You're just changing the "1.8" that was in that line to "Current" (make sure you keep the capital "C" otherwise git will get confused later).
  3. cd $(brew --repository)
  4. git add Library/brew.rb
  5. git commit -m "upgrading to ruby 2.0"
  6. brew update(or sudo brew updateif your brew is setup to only do system changes with sudo)
  1. 打开 /usr/local/Library/brew.rb (emacs/vi/nano/whatever)
  2. 将第一行更改为：#!/System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby -W0. 您只是将该行中的“1.8”更改为“当前”（确保保留大写字母“C”，否则 git 稍后会混淆）。
  3. cd $(brew --repository)
  4. git add Library/brew.rb
  5. git commit -m "upgrading to ruby 2.0"
  6. brew update（或者sudo brew update如果您的 brew 设置为仅使用 sudo 进行系统更改）

Credit: a lot of this came from here, though I really recommend against doing git commit -amin your /usr/local folder.

信用：很多都来自这里，尽管我真的建议不要git commit -am在您的 /usr/local 文件夹中这样做。

Like the one before said: 1) Change to current 2) install xcode 6

就像之前所说的那样：1）更改为当前版本 2）安装 xcode 6

If you now have further problems with brew and ruby this should help: Somehow brew needs ruby on version 1.8, so create the folder:

如果您现在对 brew 和 ruby​​ 有进一步的问题，这应该会有所帮助：不知何故 brew 在 1.8 版上需要 ruby​​，因此创建文件夹：

sudo mkdir -p /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin

and make a symlink:

并制作一个符号链接：

sudo ln -s /usr/bin/ruby /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby

Note: Only do the below if you end up in a completely failed state, as this is very DANGEROUS

注意：仅当您最终处于完全失败的状态时才执行以下操作，因为这是非常危险的

As an example I kept getting

作为一个例子，我不断得到

$ sudo ln -s Current 1.8

$ brew update

/usr/local/Library/brew.rb:18:in ': undefined method help?' for [“update”]:Array (NoMethodError)

$ sudo ln -s 当前 1.8

$ brew 更新

/usr/local/Library/brew.rb:18:in '：未定义的方法帮助？' 对于 [“更新”]：数组（NoMethodError）

I just get this…(no matter what command just switch out “update” with the command) I solved the problem by asking for a buddies /usr/localfolder. I then made a backup of my /usr/localfolder.

我只是明白了……（不管是什么命令，只需用命令切换“更新”）我通过请求一个好友/usr/local文件夹解决了这个问题。然后我备份了我的/usr/local文件夹。

sudo mv /usr/local /usr/local.orig

须藤 mv /usr/local /usr/local.orig

I then moved his /usr/localto mine

然后我把他的搬到了/usr/local我的

sudo mv ~/Downloads/local /usr/local

须藤 mv ~/Downloads/local /usr/local

Note: You will likely lose some data so make sure to make a backup.

注意：您可能会丢失一些数据，因此请务必进行备份。
