以 root 身份安装没有 rvm 的 Gems，使用显式版本的 ruby [英] Installing Gems without rvm, as root, with explicit version of ruby

问题描述

我决定摆脱 rvm，但我在使用新版本的 ruby​​ 1.9.2 编译 gem 时遇到了麻烦.gem 需要 1.9.2，我有，但说没有它就无法安装，所以错误消息没有意义.

I've decided to get rid of rvm, and I'm having trouble compiling a gem with my new version of ruby 1.9.2. The gem requires 1.9.2, I have it, yet says it can't install without, so the error messages makes no sense.

如何明确告诉 gem 用上述版本的 ruby​​ 进行编译?

How can I explicitly tell the gem to compile with said version of ruby?

Gem::InstallError: linecache19 requires Ruby version >= 1.9.2.
An error occured while installing linecache19 (0.5.12), and Bundler cannot continue.
Make sure that `gem install linecache19 -v '0.5.12'` succeeds before bundling.
 apps2 ~/projects/sms/apps2/apps2_admin $ ruby -v
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-darwin10.8.0]
 apps2 ~/projects/sms/apps2/apps2_admin $ which ruby
/usr/local/bin/ruby

推荐答案

在 OS X Lion 上使用 rbenv 时，我遇到了同样的问题(linecache19 永远/无限期挂起).我发现解决方案是使用 OpenSSL 选项安装 Ruby，如下所示:

I had the same issue (linecache19 hangs forever/indefinitely) when using rbenv on OS X Lion. I found the solution was to install Ruby with OpenSSL option, like this:

rbenv install 1.9.2-p290 --with-openssl-dir=/usr/local
rbenv rehash
rbenv global 1.9.2-p290

现在，您可以运行或捆绑它，它会正常安装:

Now, you can run or bundle this and it'll install fine:

gem install ruby-debug19
