Question

由于遗留系统，我需要使用Ruby v1.8.7-p374。我一直在使用RVM来使用那个版本的Ruby，所有这些版本似乎运行良好，直到发生了变化。

现在我的系统不会使用我用RVM指定的Ruby版本。有没有办法手动切换Ruby版本？

相关问题：＆＃34; Can't change Ruby Version using RVM＆＃34;

以下是一些相关的信息：

$ rvm --default use ruby-1.8.7-p374
Using /Users/wroberts/.rvm/gems/ruby-1.8.7-p374

$ ruby -v
ruby 2.0.0p481 (2014-05-08 revision 45883) [universal.x86_64-darwin13]


$ echo $PATH

$ rvm list

rvm rubies

#  * - default

$ which ruby

$ ls /Users/wroberts/.rvm/gems/ruby-1.8.7-p374/bin/ruby 
/Users/wroberts/.rvm/gems/ruby-1.8.7-p374/bin/ruby

$ rvm info

RVM version 1.26.4 (master) is installed yet 1.26.4 (latest) is loaded.
Please do one of the following:
  * 'rvm reload'
  * open a new shell
  * 'echo rvm_auto_reload_flag=1 >> ~/.rvmrc' # for auto reload with msg.
  * 'echo rvm_auto_reload_flag=2 >> ~/.rvmrc' # for silent auto reload.

现在还有更多问题：

$ rvm install 1.8.7 --without-tcl --without-tk
Warning! PATH is not properly set up, '/Users/wroberts/.rvm/gems/ruby-1.8.7-p374/bin' is not at first place,
     usually this is caused by shell initialization files - check them for 'PATH=...' entries,
     it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles',
     to fix temporarily in this shell session run: 'rvm use ruby-1.8.7-p374'.

它正在工作 - 我的解决方法，还有一个问题

所以我做了rvm implode，（我认为）导致ruby不在System / Library / Frameworks / Ruby.framework / Versions / Current / usr / bin / ruby中。

因此，每当我尝试安装1.8.7 --without-tcl --without-tk时，我的brew文件出现问题。

几个最终问题：

我检查了brew文件，并在顶部使用

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

我将其改为

#!/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -W0

现在brew工作了，我能够安装1.8.7并且做rvm --default使用ruby-1.8.7-p374和我的宝石安装等。

第一个问题，这个hacky解决方案对我来说是一个主要问题，不是一个大问题，或者由于问题的愚蠢而导致未知领域？

第二个问题，每次我打开一个新的bash shell ruby -v都给了我（我相信）系统版本的ruby：

$ ruby -v
ruby 2.0.0p481 (2014-05-08 revision 45883) [universal.x86_64-darwin13]
$ which ruby
/usr/bin/ruby

然后我设置了默认的rvm并希望这会自动发生，

$ rvm --default use ruby-1.8.7-p374
Warning! PATH is not properly set up, '/Users/wroberts/.rvm/gems/ruby-1.8.7-p374/bin' is not at first place,
     usually this is caused by shell initialization files - check them for 'PATH=...' entries,
     it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles',
     to fix temporarily in this shell session run: 'rvm use ruby-1.8.7-p374'.
Using /Users/wroberts/.rvm/gems/ruby-1.8.7-p374
$ ruby -v
ruby 1.8.7 (2013-06-27 patchlevel 374) [i686-darwin13.4.    
$ which ruby
/Users/wroberts/.rvm/rubies/ruby-1.8.7-p374/bin/ruby

它说我的路径没有正确设置，但如果你查看这篇文章的顶部，/ Users / wroberts / .rvm / gems / ruby-1.8.7-p374 / bin是第一位的，怎么能这是固定的吗？

Answer 1

RVM告诉你它不喜欢shell的配置。所以试试

rvm get stable --auto-dotfiles

正如它所暗示的那样。 RVM需要是shell配置中包含的最后一个东西，否则它的功能会受到后面加载的shell命令的影响。

如果你使用自制软件，我会做更新和医生。

Answer 2

执行：

rvm implode
install rvm

一次。这应该可以解决问题。

Ruby版本和rvm不同步，Ruby解释器版本没有变化
