升级ruby版本遇到的一些问题

前段时间在玩Chef-一个IT基础设施自动化工具。由于Chef是由Ruby写的一个gem，那么就需要安装Ruby。当然Ruby我早就安装了，并且使用rvm来管理Ruby及Gem。本来一切看似正常，但是不会预料后面会遇到那么多的坑。

Chef本地的repo包中有一个vagrant虚拟机的模板文件，通过它可以setup一个虚拟机，然后使用Chef来操作这个节点。那么就使用vagrant命令来setup这个虚拟机把。

1 2 3 4 5 6 7 8 9 10 11 12 13 14

$ vagrant up --no-color Vagrant failed to initialize at a very early stage: It appears that you've ran a newer version of Vagrant on this computer. Unfortunately, newer versions of Vagrant change internal directory layouts that cause older versions to break. This version of Vagrant cannot properly run. If you'd like to start from a clean state, please remove the Vagrant state directory: /Users/twer/.vagrant.d Warning that this will remove all your boxes and potentially corrupt existing Vagrant environments that were running based on the future version.

console中说Vagrant版本有问题，那么就按说明删除.vagrant.d文件夹把。

1 2 3 4 5 6

$ rm -rf ~/.vagrant.d/ $ vagrant up --no-color /Users/twer/sourcecode/chef-repo/Vagrantfile:8:in `(required)>': undefined method `configure' for Vagrant:Module (NoMethodError) from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/vagrant-1.0.7/lib/vagrant/config/loader.rb:115:in `load' from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/vagrant-1.0.7/lib/vagrant/config/loader.rb:115:in `block in procs_for_source' from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/vagrant-1.0.7/lib/vagrant/config.rb:41:in `block in capture_configures'

窝里个去，又出新问题了。那好吧，看看当前ruby的版本。

1 2 3 4 5 6 7 8 9 10

$ rvm list rvm rubies ruby-1.9.2-p320 [ x86_64 ] =* ruby-1.9.3-p194 [ x86_64 ] # => - current # =* - current && default # * - default

试着将Ruby的版本切换到1.9.2-p320再试试。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

$ rvm use ruby-1.9.2-p320 Using /usr/local/rvm/gems/ruby-1.9.2-p320 $ vagrant up Bringing machine 'default' up with 'virtualbox' provider... [default] Setting the name of the VM...

This can take a few minutes. [default] VM booted and ready for use! [default] Setting hostname... [default] Mounting shared folders... [default] -- /vagrant

搞定。看来问题是当前使用的ruby的版本有问题。

老是使用旧版本也不是个事，把Ruby升级到最新版本看还有这个问题不。

1 2 3 4 5 6 7 8 9 10 11

$ rvm list known # MRI Rubies [ruby-]1.8.6[-p420] [ruby-]1.8.7[-p374] [ruby-]1.9.1[-p431] [ruby-]1.9.2[-p320] [ruby-]1.9.3[-p448] [ruby-]2.0.0-p195 [ruby-]2.0.0[-p247] [ruby-]2.0.0-head ruby-head

看来ruby的1.9.3已经有p448了，那么就升级到p448。

1 2 3 4 5 6 7 8

$ rvm install 1.9.3 Checking requirements for osx. Installing requirements for osx. Updating system. Installing required packages: libksba, openssl.......... Error running 'requirements_osx_brew_libs_install gcc libksba openssl', please read /usr/local/rvm/log/1379843991_ruby-1.9.3-p448/package_install_gcc_libksba_openssl.log Requirements installation failed with status: 1.

升级失败，那么看看log。

1 2 3 4 5 6 7 8 9 10 11 12

==> make bootstrap configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. make[2]: *** [configure-stage1-target-libgcc] Error 1 make[1]: *** [stage1-bubble] Error 2 make: *** [bootstrap] Error 2 READ THIS: https://github.com/mxcl/homebrew/wiki/troubleshooting There were package installation errors, make sure to read the log. Try `brew tap --repair` and make sure `brew doctor` looks reasonable.

通过看log是gcc编译失败，并且通过log可以看出rvm是通过homebrew来安装必备文件的。

通过一番查资料后，找到了解决办法。那就是将Xcode升级到最新版本，然后在Preference里选择Downloads标签，然后安装Command Line Tools。

安装完毕后再用Homebrew安装gcc49。

1 2 3 4 5 6 7 8 9 10 11 12

$ brew install gcc49 ==> Downloading ftp://gcc.gnu.org/pub/gcc/snapshots/4.9-20130915/gcc-4.9-20130915.tar.bz2 Already downloaded: /Library/Caches/Homebrew/gcc49-4.9-20130915.tar.bz2 ==> ../configure --build=x86_64-apple-darwin12.5.0 --prefix=/usr/local/Cellar/gcc49/4.9-20130915/gcc ==> make bootstrap ==> make install ==> Caveats This is a snapshot of GCC trunk, which is in active development and supposed to have bugs and should not be used in production environment. ==> Summary �� /usr/local/Cellar/gcc49/4.9-20130915: 977 files, 93M, built in 21.6 minutes

成功安装GCC。

继续回到安装Ruby的任务上来。由于在安装Ruby前会先安装必备文件，那么干脆直接先安装必备文件的了。

1 2 3 4 5 6

$ rvm requirements Checking requirements for osx. Installing requirements for osx. mkdir: /usr/local/rvm/log/1379829979_ruby-1.9.3-p448: Permission denied tee: /usr/local/rvm/log/1379829979_ruby-1.9.3-p448/update_system.log: No such file or directory tee: /usr/local/rvm/log/1379829979_ruby-1.9.3-p448/update_system.log: No such file or directory

我勒个去，貌似是权限问题，那么用sudo解决。

1 2 3 4 5 6 7 8 9

$ sudo rvm requirements Checking requirements for osx. Installing requirements for osx. Updating system. Installing required packages: libksba, openssl.......... Error running 'requirements_osx_brew_libs_install libksba openssl', please read /usr/local/rvm/log/1379843991_ruby-1.9.3-p448/package_install_libksba_openssl.log Requirements installation failed with status: 1.

又失败，看看错误日志吧。

1 2 3 4 5 6 7 8 9 10

current path: /Users/twer command(3): requirements_osx_brew_libs_install libksba openssl Error: No such keg: /usr/local/Cellar/libksba Error: Cowardly refusing to `sudo brew install` You can use brew with sudo, but only if the brew executable is owned by root. However, this is both not recommended and completely unsupported so do so at your own risk. There were package installation errors, make sure to read the log.

看了日志貌似明白了，使用brew安装libksba由于加了sudo所以出问题了。那么直接在命令行使用sudo试试。

1 2 3 4 5

$ sudo brew install libksba Error: Cowardly refusing to `sudo brew install` You can use brew with sudo, but only if the brew executable is owned by root. However, this is both not recommended and completely unsupported so do so at your own risk.

窝里个去，不使用sudo吧rvm requirements执行不成功。加上sudo吧rvm requirements调用的brew install又不行。好吧，就按上面说的将brew转换到root模式。

1 2 3 4 5 6

ls -al /usr/local/bin/brew -rwxr-xr-x 1 twer admin 703 Mar 14 2013 /usr/local/bin/brew $ sudo chown root:admin /usr/local/bin/brew Password: $ ls -al /usr/local/bin/brew -rwxr-xr-x 1 root admin 703 Mar 14 2013 /usr/local/bin/brew

OK。再执行吧。

1 2 3 4 5

$ sudo rvm requirements Password: Checking requirements for osx. Certificates in '/usr/local/etc/openssl/cert.pem' already are up to date. Requirements installation successful.

搞定。把brew再切换到原来的用户和组。

1	$ sudo chown twer:admin /usr/local/bin/brew

绕了一大圈了终于可以安装Ruby了。

又有错。走到这步上了，继续解决吧。经过分析貌似是下载文件有问题，可能又是权限问题。

前面那个错没了，但是新来了一个错。貌似是ssh到rubygems.org网站有问题，突然想起在rvm requirements时安装了openssl，应该是ssl设置的问题。从网上查了下，貌似要重置macport。

$ sudo rm -rf /opt/local $ sudo rm -rf $rvm_path/usr $ sudo rm -rf $rvm_path/bin/port sudo: cannot get working directory $ sudo rvm autolibs homebrew

最后，再重新安装Ruby。

终于将Ruby升级到1.9.3-p448了。回顾这整个过程，都是泪啊。本来是想装个虚拟机玩玩，哪想到惹出这么多事情来。不过好歹问题是解决了。
