Errno:：EACCES:mkdir上的权限被拒绝jruby错误

我正在使用ubuntu 14.04 LTS。我正在使用rvm和ruby。 rvm列表给出以下输出：

Warning! PATH is not properly set up, '/home/rujoota/.rvm/gems/jruby-1.7.19/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 jruby-1.7.19'.

rvm rubies

=* jruby-1.7.19 [ x86_64 ]
   ruby-1.9.3-p551 [ x86_64 ]
   ruby-2.2.1 [ x86_64 ]

 => - current

 =* - current && default

 *- default

我尝试了一切，但警告仍然出现

当我尝试运行ruby应用程序时，出现以下错误：

Errno::EACCES: Permission denied - /myfolder
mkdir at org/jruby/RubyDir.java:452
fu_mkdir at /home/myhome/.rvm/rubies/jruby-1.7.19/lib/ruby/1.9/fileutils.rb:247

我对myfolder和.rvm具有完全访问权限。仍然面临这个问题，有人能帮我吗？

试试jruby 1.7.22。。。如果它在Mrity jruby 1.7.22下工作，可能是一个bug。。。如果它在核磁共振成像下工作，可能是个错误
