Errors in run "bundle install"

Hi all.
When I run "bundle install", failed, and see these errors:
"checking for rb_io_t in ruby.h,rubyio.h... no
checking for OpenFile.fd in ruby.h,rubyio.h... no

What can I do?

Hi, all.

This is because of the ruby's installation version. Reinstalling Ruby 2.4 with RVM will solve the problem.

Installing RVM:

$sudo apt install gnupg2
$gpg2 --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
$url -sSL https://get.rvm.io | bash -s stable
$source ~/.rvm/scripts/rvm

Installing ruby 2.4

$rvm install 2.4
$rvm use 2.4.10 --default

Everything is OK!
