"gem install bundler --version=0.8.1" doesn't install the bundle executable

Question

When trying to install Bundler 0.8.1 on Ubuntu machine, it install fine but the executable "bundle" is no where to be seen. Other gems install successfully, including their executables.

using: gem install bundler --version=0.8.1

RubyGems Environment:
- RUBYGEMS VERSION: 1.3.7
- RUBY VERSION: 1.8.7 (2009-06-12 patchlevel 174) [i486-linux]
- INSTALLATION DIRECTORY: /home/ahammad/gems

- REMOTE SOURCES:

Path /home/ahammad/gems/bin has been added to PATH, the problem is there is no bundle exe.

Any ideas?

Maybe that specific version of bundler wasn't available for installation, so to choose specific available range of versions which could be available, try:

gem install bundler --version '<= 0.10.6'

Or simple uninstall the previous bundler and install it again. Then check by gem list bundler or bundler _0.9.26_ -v (where 0.9.26 is version of your older gem).

Check also the permissions of your local gem folders.
