**Running `composer create-project laravel9 appnamehere` fails because Composer interprets `laravel9` as a package name rather than a version constraint, preventing folder creation; the correct command is `composer create-project --prefer-dist laravel/laravel="9.*" appnamehere`.**

When attempting a **laravel 9 install** via command line, developers frequently encounter silent failures where the target directory is never created. This occurs due to a syntax misunderstanding in how Composer resolves package names versus version constraints. According to the `laravel/framework` source code, successful installation requires specifying the official `laravel/laravel` skeleton repository with an explicit version constraint that maps to the 9.x release line.

## Why `composer create-project laravel9` Fails to Create Folders

When you execute `composer create-project laravel9 appnamehere`, Composer treats **`laravel9`** as the package identifier to fetch from Packagist, not as a version specification. Because no package named `laravel9` exists in the registry, Composer throws a `[Composer\Downloader\TransportException] Could not download…` error and aborts before writing any files to disk. The target folder is never created because the dependency resolution phase fails upstream.

## Correct Laravel 9 Install Command Syntax

To perform a valid **laravel 9 install**, you must specify the `laravel/laravel` skeleton package and append a version constraint that isolates the 9.x branch:

```bash
composer create-project --prefer-dist laravel/laravel="9.*" appnamehere

```

Alternatively, you can use caret notation:

```bash
composer create-project --prefer-dist laravel/laravel:^9.0 appnamehere

```

**Key components of the command:**

- **`laravel/laravel`** – The official starter repository containing the default application structure (routes, controllers, configuration files).
- **`="9.*"` or `^9.0`** – A version constraint that instructs Composer to resolve the latest 9.x release of the skeleton, which in turn requires `illuminate/*` packages from the framework repository.
- **`appnamehere`** – The target directory that Composer will create and populate. This path must not exist, or must be completely empty, to avoid write conflicts.

### Understanding the Package Structure

The `laravel/laravel` repository serves as the application skeleton, while `laravel/framework` provides the core `Illuminate` components. During installation, Composer reads the skeleton's [`composer.json`](https://github.com/laravel/framework/blob/main/composer.json) (located at `https://github.com/laravel/laravel/blob/9.x/composer.json`), which declares `"laravel/framework": "9.*"` in its requirements, ensuring the correct framework version is pulled from the `laravel/framework` repository.

## What Happens Under the Hood

When you run the correct **laravel 9 install** command, Composer performs the following steps according to the framework source:

1. **Skeleton Resolution** – Composer clones the `laravel/laravel` repository and reads its [`composer.json`](https://github.com/laravel/framework/blob/main/composer.json) to determine dependency requirements.
2. **Framework Resolution** – Based on the skeleton's requirements, Composer resolves the `illuminate/*` packages (such as `illuminate/support` and `illuminate/database`) from the `laravel/framework` repository's [`composer.json`](https://github.com/laravel/framework/blob/main/composer.json) (found at `https://github.com/laravel/framework/blob/9.x/composer.json`).
3. **File Generation** – Composer copies the skeleton files into the target directory, including the `artisan` entry point and [`src/Illuminate/Foundation/Application.php`](https://github.com/laravel/framework/blob/main/src/Illuminate/Foundation/Application.php), which handles service provider registration during bootstrap.
4. **Post-Install Hook** – Finally, Composer executes `php artisan key:generate` to create the application encryption key, completing the installation.

## Common Pitfalls During Laravel 9 Installation

| Symptom | Cause | Remedy |
|---|---|---|
| "Could not find a matching package" | Using `laravel9` instead of `laravel/laravel` as the package name | Use the correct package identifier `laravel/laravel` |
| Folder not created but no error shown | Target directory already exists and contains files | Delete or rename the existing folder, or specify a new path |
| "Your PHP version is 7.x, but Laravel 9 requires ≥ 8.0" | Local PHP runtime below minimum requirement | Upgrade to PHP 8.0 or higher before installation |
| Version resolution ignores constraints | Outdated Composer binary | Run `composer self-update` to ensure modern constraint parsing |

## Practical Code Examples

```bash

# Standard Laravel 9 install with strict version pinning

composer create-project --prefer-dist laravel/laravel="9.*" my-laravel-9-app

# Using caret syntax for semantic versioning

composer create-project --prefer-dist laravel/laravel:^9.0 my-laravel-9-app

# Non-interactive mode for CI/CD pipelines

composer create-project --prefer-dist --no-interaction laravel/laravel="9.*" ci-laravel-9

# Verify the installation

cd my-laravel-9-app
php artisan --version

```

## Summary

- **Use the correct package name** – Specify `laravel/laravel`, not `laravel9`, as the first argument to `composer create-project`.
- **Apply a version constraint** – Append `="9.*"` or `^9.0` to ensure Composer resolves the 9.x skeleton and corresponding `illuminate/*` framework packages.
- **Check PHP compatibility** – Laravel 9 requires PHP 8.0 or higher; verify your environment with `php -v` before installing.
- **Ensure directory availability** – The target folder must not exist (or must be empty) to prevent Composer from aborting the file generation phase.
- **Understand the dependency chain** – Composer resolves versions by reading the skeleton's [`composer.json`](https://github.com/laravel/framework/blob/main/composer.json), which references the framework repository's [`composer.json`](https://github.com/laravel/framework/blob/main/composer.json) to pull core components like [`src/Illuminate/Foundation/Application.php`](https://github.com/laravel/framework/blob/main/src/Illuminate/Foundation/Application.php).

## Frequently Asked Questions

### Why does Composer report that it cannot find the `laravel9` package?

Composer interprets the first argument after `create-project` as the package name to fetch from Packagist. Since `laravel9` is not a registered package, the command fails during the download phase. You must use `laravel/laravel` as the package name and specify the version using a constraint like `="9.*"`.

### Can I install Laravel 9 into a folder that already exists?

No. Composer requires the target directory to either not exist or be completely empty. If the folder contains any files, including hidden files like `.gitignore`, Composer will abort to prevent accidental overwrites. Delete or rename the existing directory before running the installation command.

### What PHP version is required for a Laravel 9 install?

Laravel 9 requires **PHP 8.0 or higher**. If your local environment runs PHP 7.x, Composer will halt with a dependency resolution error stating that your PHP version does not satisfy the `"php": "^8.0"` requirement found in the framework's [`composer.json`](https://github.com/laravel/framework/blob/main/composer.json).

### How does Composer determine which framework version to install alongside the skeleton?

The `laravel/laravel` skeleton's [`composer.json`](https://github.com/laravel/framework/blob/main/composer.json) explicitly requires `"laravel/framework": "9.*"`. When Composer processes this requirement, it queries the `laravel/framework` repository and resolves the specific `illuminate/*` package versions (such as `illuminate/support` and `illuminate/database`) that correspond to the 9.x release line, ensuring version compatibility across the application stack.
