如何使用"RVM --default"在MacOSX上 [英] How to use "RVM --default" on MacOSX

问题描述

在使用Ruby和Rails一段时间之后，我想尝试RVM.一切正常，除了一件事:

After using Ruby and Rails for quite some time now, I wanted to try RVM. Everything works fine, except for one thing:

在新打开的终端中，ruby指向系统的红宝石，尽管事实是我使用了rvm --default命令.

In a freshly opened Terminal ruby points to the system's ruby, despite the fact, that I used the rvm --default command.

user@terra ~ $ ruby -v
ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-darwin10]
user@terra ~ $ which ruby
/opt/local/bin/ruby
user@terra ~ $ rvm list
   ruby-1.8.7-p334 [ ]
=> ruby-1.9.2-p180 [ ]

打电话给rvm reload

user@terra ~ $ rvm reload
user@terra ~ $ ruby -v
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-darwin10.7.1]
tmangner@terra ~ $ which ruby
/Users/user/.rvm/rubies/ruby-1.9.2-p180/bin/ruby

我按照文档中的说明设置了.bash_profile:

I set up my .bash_profile as described in the documentation:

[[ -s "/Users/user/.rvm/scripts/rvm" ]] && source "/Users/user/.rvm/scripts/rvm" 

那个--default似乎对我不起作用...

That --default does not seem to work for me ...

user@terra ~ $ rvm use 1.9.2 --default
Using /Users/user/.rvm/gems/ruby-1.9.2-p180
user@terra ~ $ rvm default
user@terra ~ $

推荐答案

我曾经遇到过同样的问题.原来rvm脚本被加载了两次，这使事情有点混乱了.

I had the same problem once. It turned out the rvm-script got loaded twice, which broke things a bit.

检查打开外壳程序时加载的所有文件:

Check all the files that load when you open a shell:

/etc/profile
~/.bashrc
~/.bash_profile

，依此类推，并确保它们不会两次加载RVM.

and so on, and make sure they don't load RVM twice.

也许放

echo "Going to load RVM"

之前

[[ -s "/Users/user/.rvm/scripts/rvm" ]] && source "/Users/user/.rvm/scripts/rvm"

在您的~/.bash_profile中

查看它是否发生.

in your ~/.bash_profile to see if it happens or not.
