Unable to install bson_ext 1.8.2 gem

Question

I am unable to install the bson_ext 1.8.2 gem in my mongo project directory. In specific I tried running bundle install and gem install bson_ext -v '1.8.2'

I tried other solutions present on the forum but in vain.

An error occurred while installing bson_ext (1.8.2), and Bundler cannot continue.
Make sure that `gem install bson_ext -v '1.8.2'` succeeds before bundling.

gem install bson_ext -v '1.8.2 fails with the same error.

The solution here(https://jira.mongodb.org/browse/RUBY-551?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel) says its fixed....but i still face the same

Try updating rubygems and then installing bson_ext.

gem update --system
gem install bson_ext
