如何让Ruby/Homebrew/RVM在Yosemite上运行？

Question

安装Yosemite后,我无法运行brew或ruby.

我在brew更新时收到此错误:

/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

在irb上收到此错误:

Answer 1

可以通过以下步骤轻松修复此错误:

1)打开终端

2)类型 nano /usr/local/Library/brew.rb

3)在第一行中将"1.8"更改为"Current",因此它应如下所示:

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

Answer 2

我更新了约塞米蒂,后来发现它brew被打破了.

/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

如果您还没有对brew进行任何更改,我推荐这里.否则请阅读以下内容.

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

已经对brew文件进行了更改并陷入混乱？

我试图编辑,/usr/local/Library/brew.rb但我的git仓库的本地更改阻止brew update了更新.我尝试了本页和其他网站上提到的其他一些解决方案,我最终得到了一个混乱,我想要做的就是撤消我所做的所有酿造工作.

我做出了改变,但事情变得更糟.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.我的版本的文件,乱七八糟太(我改变文件的权限在/ usr /本地),所以我做了git clean -f -d它删除了所有版本的文件和目录,并让我回到我开始之前,我所做的任何更改.

Answer 3

修复它的步骤:

1. 安装Xcode 6的命令行工具

2. 重新安装brew:

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

3. 一旦安装brew,rvm将起作用:

   rvm install ruby
   

为我工作,雅虎!

Answer 4

编辑脚本意味着brew update不起作用; 对跟踪文件进行本地编辑会导致git pull失败.

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

没有投诉brew doctor.

Answer 5

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起,所以一个完整的答案就在一个地方.具体来说,这可以让事情现在起作用,但也可以让你像往常一样刷新更新,让一切恢复干净.

1. 打开/usr/local/Library/brew.rb(emacs/vi/nano /等)
2. 将第一行更改为:#!/System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby -W0.你只是将那行中的"1.8"改为"当前"(确保你保留大写"C",否则git会在以后混淆).
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)

信用:很多都来自这里,但我真的建议git commit -am你不要在你的/ usr/local文件夹中做.
