Before that, gem passenger (v5.0.30) and rails 4.2.0 have been installed. What causes the error?

Answer 1

Had the same problem,

What I did:

gem uninstall bundler -v1.13.1

(or gem uninstall bundler -v1.13)

Then

gem install bundler -v 1.12

Then passenger-install-apache2-module works.

Answer 2

Check if you have the right version of RubyGems

$ gem -v

2.6.5 (or superior)

---

If you have not, upgrade your RubyGems:

$ gem update --system

If you can't use sudo like this:

$ sudo gem update --system

---

Now check you have the last bundler version:

$ bundle -v

Bundler version 1.13.0 (or superior)

---

If you have not, upgrade your Bundler:

$ gem install bundler
