This happened to me after upgrading MacOS to version “High Sierra” on my MacBook. I cloned my application repository and went to execute a bundle install command, but it throws the following error message:
So I tried to enter password and install the bundled gems to RubyGems using sudo. But this did not solve the problem and here’s what I saw:

Looks good. Let’s now try to run the bundle install command:
And it worked.
