Composer Global Require Laravel/Installer Not Working

When trying to install the Laravel installer globally using the command composer global require laravel/installer, you might encounter errors or issues that prevent the installation from completing successfully. These issues can be due to misconfigurations, permission problems, or other environment-specific factors. Below, we'll break down the most common causes and walk through a step-by-step guide to resolving this problem.

Step 1: Verify Composer Installation

Before running the command, make sure Composer is correctly installed on your system. Run the following command to check if Composer is installed and accessible globally:

Command: composer -v

If Composer is not installed or the command isn’t recognized, you will need to install it first. Follow the official Composer installation guide based on your operating system.

Step 2: Ensure the Composer Global Bin Directory is in Your PATH

One of the most common issues is that the Composer global bin directory is not added to your system’s PATH. After successfully running composer global require laravel/installer, the Laravel executable should be available globally. However, if the bin directory isn't in the PATH, it won’t work.

Fix: Add Composer’s Global Bin Directory to PATH

1. Locate Composer’s Global Bin Directory:

On Unix-like systems (Linux, macOS), run the following command:

Command: composer config — global home

You should see something like:

/Users/your-username/.composer
On Windows, the directory is typically located at:
C:\Users\your-username\AppData\Roaming\Composer\vendor\bin

Add the Bin Directory to PATH:

On Unix-like systems, open your terminal and edit your shell configuration file (e.g., .bashrc, .zshrc, or .bash_profile):

Command: nano ~/.bashrc

Add the following line at the end of the file:

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

After adding this, save the file and reload your shell configuration:

source ~/.bashrc

On Windows, follow these steps:

Right-click on This PC or My Computer and select Properties.
Click on Advanced system settings.
In the System Properties window, click on Environment Variables.
Under System variables, find the Path variable, select it, and click Edit.
Add the path to your Composer's global bin directory.

Verify the Path:

Run the following command to check if Laravel installer is globally available:

Command: laravel -v

Step 3: Fix Permissions Issues

Another common reason for the failure is permission-related problems. If you’re encountering a Permission denied or similar error, it might be due to restricted write access to Composer’s directories.

Fix: Correct Permissions

1. Check Ownership and Permissions:

Navigate to the global Composer directory to check its permissions:

Command: cd ~/.composer

Use the ls -la command to see the permissions and ownership:

ls -la
Ensure that the current user has the correct ownership and permissions. If not, you can fix it by changing the ownership:
sudo chown -R $USER ~/.composer

2. Avoid Using sudo with Composer:

Using sudo with Composer can cause permission issues. If you've previously installed global packages using sudo, you may need to reset the permissions using the command mentioned above. Always try to run Composer without sudo to avoid these conflicts.

Step 4: Clear Composer Cache

Sometimes, Composer cache issues can prevent successful installation. Clearing the cache might resolve the issue.

Fix: Clear Composer Cache

Run the following command to clear Composer’s cache:

Command: composer clearcache

After clearing the cache, try running the installation command again:

Command: composer global require laravel/installer

Step 5: Update Composer

If you’re still having trouble, your Composer installation might be outdated. Update Composer to the latest version.

Fix: Update Composer

Use the following command to update Composer globally:

Command: composer self-update

Once updated, retry the Laravel installer command:

Command: composer global require laravel/installer

Step 6: Reinstall Composer or Laravel Installer

If none of the above steps work, there may be a problem with the Composer installation itself, or with the Laravel installer package.

Fix: Reinstall Composer

Uninstall and reinstall Composer following the official documentation. Make sure to backup any global Composer packages before proceeding.

Fix: Remove and Reinstall Laravel Installer

1. Uninstall Laravel Installer:

Command: composer global remove laravel/installer

2. Reinstall Laravel Installer:

After removal, reinstall the package:

Command: composer global require laravel/installer

Conclusion

By following these steps, you should be able to resolve any issues when attempting to install Laravel globally via Composer. Always ensure that your system is properly configured, permissions are correct, and that Composer’s global bin directory is in your PATH. With these common fixes, you should be able to get the Laravel installer up and running without further issues.
