wallabag: Cannot install wallbag on debian VPS

Issue details

I try to install wallbag on my VPS debian 9 server. First I install deps:

sudo apt-get install apache2 libapache2-mod-php php composer git-core php-bcmath php-gd php-dompdf php-json php-mbstring php-xml php-tidy php-symfony-polyfill-iconv php-curl php-gettext php-bcmath php-mysql make zip unzip

Next:

cd /var/www/
/var/www# git clone https://github.com/wallabag/wallabag.git
/var/www# cd wallabag/
/var/www/wallabag# make install

and that error occur:

/var/www/wallabag$ sudo make install
[sudo] password for xxxx: 
Do not run this script as root!
Use --ignore-root-warning to ignore this error.
GNUmakefile:14: recipe for target 'install' failed
make: *** [install] Error 1

or without sudo

/var/www/wallabag$ make install

Environment

• wallabag version (or git revision) that exhibits the issue: last
• How did you install wallabag? Via git clone or by downloading the package? git clone
• Last wallabag version that did not exhibit the issue (if applicable):
• php version: PHP Version => 7.0.33-0+deb9u3
• OS: Debian 9, uname -a Linux ArubaVPN 4.9.0-9-amd64 #1 SMP Debian 4.9.168-1+deb9u4 (2019-07-19) x86_64 GNU/Linux
• type of hosting (shared or dedicated): VPS

I block login as root on my server, just login as normal user and use sudo. I’m not experienced in servers just install openvpn on that server first time.
