Composer-Setup downloads and installs Composer so you can use it easily from the command line.
- it looks for PHP on your computer
- it adds PHP to the path
- it installs Composer globally - just type
composerfrom any location to use it
- it lets you use the Command Prompt, Git Bash, Msys, Msys2 and Cygwin (including cygwin php)
- it can be deployed unattended for silent installs/uninstalls
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.
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 creates a log file, which may be useful to review if you experience any issues. This is stored in your
AppData\Local\Temp with a formatted filename:
Setup Log YYYY-MM-DD #nnn.txt.
The uninstall program is available from the Control Panel. Go to Programs and Features, select Composer, then click Uninstall. This offers the option to remove user cache and configuration data.
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 are an Administrator or not.
Admin install for all users:
C:\<Program Files>\ComposerSetup- uninstaller
C:\ProgramData\ComposerSetup\bin- composer files
C:\Users\<user>\AppData\Local\ComposerSetup\bin- composer files
Note: These locations are fixed because Composer needs a guaranteed, persistent, writable location to perform its updates.
The installer will modify your system path for Admin installs, or your user path for User installs:
- the path to PHP will be added/replaced
- the path to the composer files directory will be added/replaced
In addition the installer will add the following to the user environment:
C:\Users\<user>\AppData\Roaming\Composer\vendor\bindirectory to your path
http_proxyvalue, if 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.
