Ruby: How to install a specific version of a ruby gem?
Use the -v flag:
$ gem install fog -v 1.8
How to run a specific version of a ruby gem
I can't reproduce this issue, but I can think of a few reasons why this might happen:
- Bundler artifacts (perhaps in
.bundle/) pointing to the old version. Try running in a different directory and see if it still happens - A bug in RubyGems (try
gem update --system) - During install, it asked if you wanted to replace the
brakemanbinary and you selected "no" - If you are using a Ruby version manager, maybe one version is on a different path than another (like a system gem versus one managed by
rvm) - Any number of
GEM_PATH,bundler,gem,rvmweirdness that sometimes occurs
In any case, if I were you I'd gem uninstall brakeman, remove all versions, and install fresh. If you are using rvm, start with a fresh gemset or rvm gemset empty the current one.
