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.
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).

Here's how to do it:
1. Use the composer global require
command
Run this command in your terminal:

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
withoutglobal
.Basically: use
global
for tools, not for app dependencies.The above is the detailed content of How to install a package globally with Composer?. For more information, please follow other related articles on the PHP Chinese website!
