ketika saya mencoba "sudo gem install rubocop", saya ...

Jadi saya telah mencoba sejumlah solusi, khususnya yang dari /programming/22544754/failed-to-build-gem-native-extension-installing-compass (permata berbeda, kesalahan yang sama)
Saya mencoba menginstal ulang RVM dengan "rvm instal ulang --disable-binary 2.2.0" yang membutuhkan waktu tetapi tidak memperbaikinya

ruby-dev is already the newest version (1:2.3.0+1).
The following packages were automatically installed and are no longer required:
dkms linux-headers-4.4.0-53 linux-headers-4.4.0-53-generic
linux-image-4.4.0-53-generic linux-image-extra-4.4.0-53-generic
python-appindicator python-gconf python-gi python-glade2
python-gobject python-pexpect python-ptyprocess python-xdg
Use 'sudo apt autoremove' to remove them.

Saya juga sudah mencoba "gem update --system" yang saya dapatkan ...
