bad interpreter: No such file or directory

[Na Li]

Hello,

I met a problem after i tried to upgrade my ruby version. Now i have to
uninstall ruby 1.8.7 to avoid conflict with the original ruby 1.8.6 in
MAC.

But now my problem is, when i use "rake db:migrate", it says:
"-bash: /opt/local/bin/rake: /opt/local/bin/ruby: bad interpreter: No
such file or directory"

I guess the reason is that somehow it tries to look for ruby in
/opt/local/bin, however ruby is in fact in /user/bin. I tried to write
"ln -s /user/bin/ruby /opt/local/bin/ruby" in .profile, but it doesn't
work.

Here is my environment and path:
iapc11:trunk$ which ruby
/usr/bin/ruby
iapc11:trunk$ which rake
/opt/local/bin/rake
iapc11:trunk$ which rails
/opt/local/bin/rails

iapc11:trunk$ echo $PATH
/opt/local/bin:/opt/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/teTeX/bin/i386-apple-darwin-current:/opt/local/bin:/user/bin:/Applications/TextMate.app/Contents/Resources

iapc11:trunk$ gem env

Anyone here can help? Thanks in advance.

I end up with manually moving rake from "/opt/local/bin" to "/usr/bin".
And then i create a symbol link using "sudo ln -s /user/bin/ruby
/opt/local/bin/ruby".

Hope this can help others who encounter the same problem
