gem cleanup shows error: Unable to uninstall bundler-1.0.21 when upgrade to bundler-1.0.22

问题

gem cleanup report error:

Attempting to uninstall bundler-1.0.21
Unable to uninstall bundler-1.0.21:
    Gem::InstallError: gem "bundler" is not installed

But I already cleanuped bundler 1.0.21 and upgrade to bundler 1.0.22.

I use rvm 1.10.2, ruby 1.9.3-p0, under Mac OS X 10.7.3.

Update:

I resolve this problem with the answer link

rvm gemset use global

gem uninstall xxx

回答1:

rvm @global do gem uninstall bundler

回答2:

Happened to me as well and solved it using:

rvm gem set use global

then

gem install bundler

It seems like cleanup command is unable to find out the path, did you try to uninstall using gem uninstall command?
