The Windows installer for the Composer PHP Dependency Manager. Download the latest release.
Composer-Setup downloads and installs Composer so you can use it easily from the command line.
php.ini
if required.composer
from any location to use it.Download and run the latest release and in the majority of cases this is all you need to do. The install process is described in more detail below.
Composer-Setup is written with Inno Setup, which is a powerful free installer for Windows programs.
First you must choose the installation type. By default Composer will be installed to a fixed location with a Control Panel uninstaller. You can choose Developer Mode if you want more control, which will install Composer anywhere you want without an uninstaller.
The next step is to find the location of your php.exe
, which is the PHP command line interpreter.
The installer searches common locations on your computer and presents you with its findings. If PHP
is already in your path then it will display this value. If not, or you want to choose a different
PHP, you must select from the list or hunt around manually.
The installer will then check that PHP and your path are set up correctly. If it finds any errors it
will give you the chance to fix them. It will also offer to either create or modify the php.ini
file if required settings do not exist. See Php Ini File for more information.
Next, the installer will ask if you need a proxy server to connect to the internet. If it finds any values in your Internet Settings or your environment, then the proxy url will be displayed.
After you have reviewed and accepted your settings, the installer will download Composer and set everything up. If your environment has been changed, it is important to close your current terminal and open a new one so that the changes get loaded. The installer will remind you if this is the case.
Composer-Setup will either create a new php.ini
or modify an existing file if any settings needed
by Composer are missing:
allow_url_fopen
set to On
curl
, mbstring
and open_ssl
extensions enabledWhen creating a new file, the php.ini-production file is used with extension_dir
and
date.timezone
values appropriately set. When modifying an existing file, a backup is created in
the same directory, named php.ini~orig
.
Composer-Setup creates a log file, which may be useful to review if you experience any installation
issues. This is stored in your temp directory AppData\Local\Temp
with a formatted filename:
Setup Log YYYY-MM-DD #nnn.txt
.
The uninstall program is available from the Control Panel (or Apps and Features) and is named
Composer - PHP Dependency Manager
. It offers the option to remove user cache and configuration
data (for all users, if run as an Adminstrator) from:
<user>\AppData\Local\Composer
<user>\AppData\Roaming\Composer
The uninstall program will not be available if you installed in Developer Mode. To manually uninstall you must delete the composer files from the location you installed to and update the environment.
In a default installation, the install directories are pre-determined and depend on whether you have chosen to install for All Users or the Current User.
All Users install:
C:\<Program Files>\ComposerSetup
- uninstaller.C:\ProgramData\ComposerSetup\bin
- composer files.Current User install:
C:\Users\<user>\AppData\Local\ComposerSetup
- uninstaller.C:\Users\<user>\AppData\Local\ComposerSetup\bin
- composer files.In a Developer Mode installation you can install the composer files to a location of your choice.
The installer will modify the System path for All Users installs, or the User path for Current User installs:
In addition the installer will add the following to the environment of the current user:
C:\Users\<user>\AppData\Roaming\Composer\vendor\bin
directory to your path.http_proxy
value, if a proxy is specified in the installer.The uninstaller will remove the path to the composer files directory and, if the user data was
removed, the Composer\vendor\bin
path. The PHP path and any http_proxy
value will be left intact.
The installer supports Inno Setup's Setup Command Line Parameters, although not all
of them are relevant. Of interest are the /VERYSILENT
or /SILENT
options for
Unattended Installs and the /SAVEINF=
and /LOADINF=
directives for
creating and using a settings file. The following additional parameters are available:
/PHP="folder-or-exe"
uses PHP from the specified location, adding it to the path if necessary./DEV="path"
selects Developer Mode and installs Composer to the specified path without an/PROXY=proxy-url
is the proxy url to use and save, but only if noThe uninstall program supports Inno Setup's Uninstaller Command Line Parameters, plus the following parameters:
/DELETE=local
removes <user>\AppData\Local\Composer
data./DELETE=all
additionally removes <user>\AppData\Roaming\Composer
data.Unattended installs and uninstalls require the /VERYSILENT /SUPPRESSMSGBOXES
command line options.
/DELETE=
parameter (as above), which will apply to all users if being run as an Administrator.Composer-Setup is licensed under the MIT License - see the LICENSE
