问题
by mistake I ran sudo bundle install on my project and now when I run it as myself bundle install I am getting permission denied errors (below). I tried the instructions here https://github.com/bundler/bundler/blob/master/ISSUES.md#other-problems, also tried cloning my project into a fresh directory and running bundle from there, no use. Please help!

Cloning the repo to a new directory would not help. You installed the gems to the standard gems directory instead of a bundle specific directory.
The best option is to install the bundle to a new directory and ignore the gems installed in the system path.
Try bundle install --path /home/akonsu/.new_project_bundle. You do not have to specify this option every time. It is remembered.

Also you need to set the permissions of the bundler's cache directory as mentioned in the comments (or delete it).

I had today the same issue today in my mac. I solved it by deleting the folder ~/.bundle .
After that I run bundle install --path ~/.bundle and everything was working fine again.

Read what's given on the bundler's website and no external help would be needed.
Gems will be installed to your default system location for gems. If your system gems are stored in a root-owned location (such as in Mac OSX), bundle will ask for your root password to install them there.
While installing gems, Bundler will check vendor/cache and then your system's gems. If a gem isn't cached or installed, Bundler will try to install it from the sources you have declared in your Gemfile.
The --system option is the default. Pass it to switch back after using the --path option as described below.
Install your dependencies, even gems that are already installed to your system gems, to a location other than your system's gem repository. In this case, install them to vendor/bundle.
$ bundle install --path vendor/bundle
Further bundle commands or calls to Bundler.setup or Bundler.require will remember this location.

I had the same issue today. I deleted the bundler directory from /Library/Ruby/Gems/2.3.0/ and then reinstalled bundler with sudo gem install bundler. Quite radical solution but solves the issue.

chmod 777 /usr/local/lib/ruby/gems/2.3.0/bundler/gems
