Ruby 执行 rvm 使用 2.0.0 default 时出现警告！PATH 未正确设置

以上第一次不起作用，第二次起作用.

对于任何新的shell窗口，try 将ruby版本设置为2.0.0.

做

$ rvm use 2.0.0 --default

给予

Warning! PATH is not properly set up, '/home/durrantm/.rvm/gems/ruby-1.9.3-p125/
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 --au
to-dotfiles',
         to fix temporarily in this shell session run: 'rvm use ruby-1.9.3-p125'
.
Using /home/durrantm/.rvm/gems/ruby-2.0.0-p247

然后做同样的事

$ rvm use 2.0.0 --default

now 给予 no error, i.e.

$ rvm use 2.0.0 --default
Using /home/durrantm/.rvm/gems/ruby-2.0.0-p247
durrantm.../durrantm$ 

但新的windows仍在为我提供ruby 1.9.3，而不是2.0.0

我的.bashrc文件中有:

PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
[[ -s "/home/durrantm/.rvm/scripts/rvm" ]] && . "/home/durrantm/.rvm/scripts/rvm"

我的bash_的个人资料包括:

source ~/.profile
case $- in *i*) . ~/.bashrc;; esac

try

rvm get stable

似乎有效，但在许多绿色输出的末尾显示:

Could not update RVM, get some help at #rvm IRC channel at freenode servers.

带有rvm list rubies个窗口的新终端显示:

$ rvm list rubies
Warning! PATH is not properly set up, '/home/durrantm/.rvm/gems/ruby-1.9.3-p125/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-1.9.3-p125'.

rvm rubies
