'libffi.so.8: cannot open shared object file

I upgraded Rails to 7.0.1. When I do the rails g controller Pages home, it's giving the error:

Any idea how to fix this?

Solution 1:[1]

Most probably you need to install libffi. On CentOS/RHEL/Fedora systems you will need to execute:

sudo dnf -y install libffi

Solution 2:[2]

Update my ubuntu from 20.04 to 20.10 and install Ruby version 3.0.2 and Ruby On Rails version 7.0.0 . That solved the error.

Solution 3:[3]

You can compile ffi gem with internal libffi that comes with it. Make sure the version matches:

gem install ffi --version '1.15.5' -- --disable-system-libffi

I don't know why ffi compiles fine with system libffi, but then refuses to run with it.
