'PHP error: "The zip extension and unzip command are both missing, skipping."

When I run a composer update I get this error message:

Loading composer repositories with package information
Updating dependencies (including require-dev)
    Failed to download psr/log from dist: The zip extension and unzip command are both missing, skipping.
The php.ini used by your command-line PHP is: /etc/php/7.0/cli/php.ini
    Now trying to download from source

What do I need to do to enable the zip and unzip commands so that composer can download dependencies?

Depending on your flavour of Linux and PHP version these may vary. 

(sudo) yum install zip unzip php-zip
(sudo) apt install zip unzip php-zip

This is a very commonly asked question, you'll be able to find more useful info in the aether by searching <distro> php <version> zip extension.

For servers with PHP 5.6

sudo apt-get install zip unzip php5.6-zip

Not to belabor the point, but if you are working in a Dockerfile, you would solve this particular issue with Composer by installing the unzip utility. Below is an example using the official PHP image to install unzip and the zip PHP extension for good measure.

FROM php:7.4-apache

# Install Composer
COPY --from=composer /usr/bin/composer /usr/bin/composer

# Install unzip utility and libs needed by zip PHP extension 
RUN apt-get update && apt-get install -y \
    zlib1g-dev \
    libzip-dev \
    unzip
RUN docker-php-ext-install zip

This is a helpful GitHub issue where the above is lovingly lifted from.

For Debian Jessie (which is the current default for the PHP image on Docker Hub):

apt-get install --yes zip unzip php-pclzip

You can omit the --yes, but it's useful when you're RUN-ing it in a Dockerfile.

On docker with image php:7.2-apache I just needed zip and unzip. No need for php-zip :

apt-get install zip unzip

or Dockerfile

RUN ["apt-get", "update"]
RUN ["apt-get", "install", "-y", "zip"]
RUN ["apt-get", "install", "-y", "unzip"]

sudo apt install zip unzip php7.2-zip

Actually composer nowadays seems to work without the zip command line command, so installing php-zip should be enough --- BUT it would display a warning:

As there is no 'unzip' command installed zip files are being unpacked using the PHP zip extension. This may cause invalid reports of corrupted archives. Installing 'unzip' may remediate them.

Solution 12:[12]

PHP-ZIP needs some dependancies or library missing, depends on the image from Dockerfile you need to install them first

RUN set -eux \
   && apt-get update \
   && apt-get install -y libzip-dev zlib1g-dev \
   && docker-php-ext-install zip
