PHP error: "The zip extension and unzip command are both missing, skipping."
PhpComposer PhpPhp Problem Overview
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?
Php Solutions
Solution 1 - Php
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
Solution 3 - Php
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 older Ubuntu distros i.e 16.04, 14.04, 12.04 etc
sudo apt-get install zip unzip php7.0-zip
Solution 5 - Php
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"]

Solution 11 - Php
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 - Php
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
