When runnning composer install on my laravel project I get the error:
Script php artisan clear-compiled handling the post-install-cmd event returned with error code 255
Any advice on what could be the issue? Note composer installs all the vendor packages. The full output is below:
[user@some_path]$ composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Generating autoload files
> php artisan clear-compiled
Script php artisan clear-compiled handling the post-update-cmd event returned with error code 255

Makse sure your storage/ & bootstrap/cache directory writeable.
Make sure your .env file doesent contain any spaces.
Ex:
key=value istead of key=va lue
remove the
bootstrap/cache/config.php file.
then
composer dumpautoload
composer update
Try to remove /bootstrap/compiled.php ( if you have it )

step 1 - Check your php version. If your laravel is old , then it wont support 7.x, you need to switch (check this if you are using mac) to PHP 5.6 in this case.
Step 2 - remove composer.lock and run composer install

The only thing that command does is delete the bootstrap/cache/services.php file, if it exists. Most likely, the file exists, but the permissions aren't set correctly to allow you to delete it.

i found the solution. Here is list of extensions that causes this problem.
extension=php_pdo_pgsql.dll
extension=php_pdo_sqlite.dll
extension=php_pgsql.dll
extension=php_pdo_mysql.dll
you have to uncomment all of these extensions from your php.ini
E:\wamp64\bin\php\php7.1.9\php.ini
Note :: Must check your database credential into your .env file

I assume the problem can come from multiple sources. In my case, I had a syntax error in my config/app.php. Reverted to a previous version and the remade my edits.
