Composer clear cache

Well, today I was facing the follow issue:

 1

 9

11
End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of /var/www/apps/api/vendor/symfony/symfony/d9b1f549001f508e27a7334590534b83 or
        /var/www/apps/api/vendor/symfony/symfony/d9b1f549001f508e27a7334590534b83.zip, and cannot find /var/www/apps/api/vendor/symfony/symfony/d9b1f549001f508e27a7334590534b83.ZIP, period.

    The archive may contain identical file names with different capitalization (which fails on case insensitive filesystems)
    Unzip with unzip command failed, falling back to ZipArchive class

    Invalid zip file, retrying...

It was part of the output message after executing composer install command.

Basically, it says that something was wrong with my dependency package.

How did I solve this issue?

It’s quite simple. And, the answer is by cleaning the composer cache, you can do it by running the command below.

$ composer clearcache

If you want, you can also use clear-cache command which is an alias for the clearcache one that was mentioned above.
