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?
composer update --prefer-source
I had this issue when trying to composer update
phpspec. Failed to download symfony/polyfill-ctype from dist: The zip extension and unzip command are both missing, skipping.
I am on a Mac and had problems making Homebrew work to install php extensions. So, my quick fix was to force composer
not to need to use zip by adding the --prefer-source option. This means it downloads the repo instead of a zipped package. Not a long term solution but handy to know.
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.
zip
warning goes away. RUN apt-get update && apt-get install -y zip
. It didn't request for unzip, libs nor docker-php-ext...
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.
php-zip
:D
For older Ubuntu distros i.e 16.04, 14.04, 12.04 etc
sudo apt-get install zip unzip php7.0-zip
I had PHP7.2 on a Ubuntu 16.04 server and it solved my problem:
sudo apt-get install zip unzip php-zip
Update
Tried this for Ubuntu 18.04 and worked as well.
I'm Using Ubuntu and with the following command worked
apt-get install --yes zip unzip
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"]
If you are using Ubuntu and PHP 7.2, use this...
sudo apt-get update
sudo apt-get install zip unzip php7.2-zip
I got this error when I installed Laravel 5.5 on my digitalocean cloud server (Ubuntu 18.04 and PHP 7.2) and the following command fixed it.
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.
See also Is there a problem with using php-zip (composer warns about it)
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
Try this for PHP 7.4:
sudo apt-get install zip unzip php7.4-zip
And for PHP 8.0:
sudo apt-get install zip unzip php8.0-zip
PHP 8.1
apt-get install --yes zip
The shortest command to fix it on Debian and Ubuntu (dependencies will be installed automatically):
sudo apt install php-zip
After run
apt install php-zip
and run again
composer require ...
I get the next warning and suggestion
As there is no 'unzip' nor '7z' command installed zip files are being unpacked using the PHP zip extension.
This may cause invalid reports of corrupted archives. Besides, any UNIX permissions (e.g. executable) defined in the archives will be lost.
Installing 'unzip' or '7z' (21.01+) may remediate them.

This may cause invalid reports of corrupted archives. Besides, any UNIX permissions (e.g. executable) defined in the archives will be lost.

So I suggest install unzip first.
apt install unzip
Success story sharing
apt-get install php-zip
is sufficientphp[version]-package
vsphp-package
for any given package? Would love to know as I usually just go with thephp[version]-package
version, but perhaps that's not optimal…php-<package>
is the default version. These packages just depend on the most recent version. If you need some specific (usually older) version, you installphp<version>-<package>
.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. Besides, any UNIX permissions (e.g. executable) defined in the archives will be lost. Installing 'unzip' may remediate them.
So it should beRUN … apt-get install -yqq … zlib1g-dev libzip-dev unzip && docker-php-ext-install zip
