Ubuntu Serverに zsteg をインストールしようとすると(Linux 4.8.0-49-generic x86_64
)次のエラーが発生します。
$ Sudo gem install zsteg
Building native extensions. This could take a while...
ERROR: Error installing zsteg:

Ruby2.3、Ruby-dev、およびrakeがインストールされています
また試してみました:
gem update --system
Sudo
を使用しない場合、次のようになります:ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions for the /var/lib/gems/2.3.0 directory.
助けてください。
Rakeとzstegを再インストールしただけでうまくいきました。
update --system
Sudo gem install rake
Sudo gem install zsteg
