Composer Update Failed cannot open shared object file:

I just run

composer update

but I got this

Failed loading ./opcache.so:  ./opcache.so: cannot open shared object file: No such file or directory
    PHP Warning:  PHP Startup: Unable to load dynamic library './pdo.so' - ./pdo.so: cannot open shared object file: No such file or directory in Unknown on line 0
    PHP Warning:  PHP Startup: Unable to load dynamic library './calendar.so' - ./calendar.so: cannot open shared object file: No such file or directory in Unknown on line 0
    PHP Warning:  PHP Startup: Unable to load dynamic library './ctype.so' - ./ctype.so: cannot open shared object file: No such file or directory in Unknown on line 0
   ... so on

I run php -i and got this

Loaded Configuration File => /etc/php/7.0/cli/php.ini
Scan this dir for additional .ini files => /etc/php/7.0/cli/conf.d
Additional .ini files parsed => /etc/php/7.0/cli/conf.d/10-opcache.ini,

/etc/php/7.0/cli/conf.d/20-calendar.ini,
/etc/php/7.0/cli/conf.d/20-ctype.ini,
... so on

How do I fix it?

Thanks in Advance.
