不是很了解ubuntu的命令，安装mastodon官方的教程到这一步时
apt install -y \ imagemagick ffmpeg libpq-dev libxml2-dev libxslt1-dev file git \ g++ libprotobuf-dev protobuf-compiler pkg-config nodejs gcc autoconf \ bison build-essential libssl-dev libyaml-dev libreadline-dev \ zlib1g-dev libncurses5-dev libffi-dev libgdbm-dev \ nginx redis-server redis-tools postgresql postgresql-contrib \ certbot python-certbot-nginx yarn libidn11-dev libicu-dev libjemalloc-dev
