Not able to install composer in laravel project

Question

I am new in Php and start working on laravel based project but facing one issue when installing composer on project level (I am using Phpstrom Ide).

composer install --no-interaction --ansi Loading composer repositories with package information Installing dependencies (including require-dev) from lock file Nothing to install or update Generating optimized autoload files > Illuminate\\Foundation\\ComposerScripts::postInstall > php artisan optimize Script php artisan optimize handling the post-install-cmd event returned with error code 1 Failed to install packages for ./composer.json.

Process :-

1. Install composer and wamp server
2. Hit this command in order to create laravel project

composer create-project laravel/laravel --prefer-dist

and project is created with this error and no vendor folder is created

Installing laravel/laravel (v5.4.30) - Installing laravel/laravel (v5.4.30): Downloading (100%) Created project in C:\\wamp64\\www\\laravel

php -r "file_exists('.env') || copy('.env.example', '.env');" Script php -r "file_exists('.env') || copy('.env.example', '.env');" handling th e post-root-package-install event returned with error code 1

Answer 1

[Symfony\\Component\\Console\\Exception\\RuntimeException] The "-e" option does not exist.

Above error comes because of options shortcuts… here composer - version means composer -v … and which is not working in your case. That's the reason behind the last error stack.

Refer this link to see GitHub issue. the -e option does not exist

instead of running composer -version try to run

composer --version

and see it shows composer version or not...if not then the composer is not installed properly.

Then run

laravel --version

if you don't see version there. install composer and laravel again. Below link will be helpful for step by step installation.

laravel new doesn't work

Answer 2

It seems that composer is not properly installed on your environment...

Follow the official documentation and try again to install your dependencies.

Let me know if this solution worked.
