To install the Composer package globally, you need to use the composer global require command, 1. Execute composer global require vendor/package-name to install the package to the global vendor directory; 2. Make sure that the Composer bin directory (such as ~/.composer/vendor/bin or C:\Users\YourName\AppData\Roaming\Composer\vendor\bin) has been added to the system PATH to run the executable file; 3. Update or composer global update via composer global update vendor/package-name uninstalls the global package. This method is suitable for CLI tools used across projects, such as laravel/installer or php-cs-fixer, and only needs to configure PATH once to take effect permanently.

How to install a package globally with Composer?

To install a package globally with Composer, you use the global keyword. This installs the package into a central Composer directory on your system, making its executables available globally (assuming the Composer bin directory is in your system's PATH).

How to install a package globally with Composer?

Here's how to do it:

1. Use the composer global require command

Run this command in your terminal:

How to install a package globally with Composer?
 composer global require vendor/package-name

For example, to install Laravel's installer globally:

 composer global require laravel/installer

This installs the package into Composer's global vendor directory (usually located at ~/.composer/vendor on Linux/macOS or C:\Users\YourName\AppData\Roaming\Composer\vendor on Windows).

2. Make sure the Composer bin directory is in your PATH

After installing a global package, you can run its binaries (like laravel , phpcs , etc.) only if the Composer bin directory is in your system's PATH .

The global Composer bin directory is typically:

  • Linux/macOS : ~/.composer/vendor/bin
  • Windows : C:\Users\YourName\AppData\Roaming\Composer\vendor\bin

Add it to your shell profile (like .bashrc , .zshrc , or system environment variables on Windows):

 export PATH="$HOME/.composer/vendor/bin:$PATH"

Then reload your shell:

 source ~/.zshrc # or ~/.bashrc

? Tip: You only need to do this once. After the bin directory is in your PATH, all future global packages will be executed automatically.


3. Updating or removing global packages

  • Update a global package:

     composer global update
  • Remove a package:

     composer global remove vendor/package-name

    Common use cases

    Global packages are typically CLI tools, such as:

    • laravel/installer
    • phpunit/phpunit
    • squizlabs/php_codesniffer
    • friendsofphp/php-cs-fixer

    These tools are meant to be used across multiple projects, so installing them globally avoids duplication.


    Just remember: global doesn't mean “available in every project” — it means “installed once, usable from anywhere via command line.” For project-specific dependencies, always use composer require without global .

    Basically: use global for tools, not for app dependencies.
