artisan clear-compiled return error code 255

Question

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

From all the random "correct" answers, I can deduct that this comes from an error in code, but it may be anywhere in the project. For me, it was on the Exception Handler. I extended a class that was not available. Good luck finding out the source for real problem. — JoeGalind, Dec 18 '19 at 20:12

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 )

And make sure you HAVE a .env file, in my n00b case. – Ciabaros May 11 '21 at 17:54
Also make sure your autoloaded directories like `src` in many cases do not contain fatal errors for parsing. – WebDevPassion Feb 22 '23 at 08:47

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.

Just run the npm install command from any terminal then re-run composer to install all your dependencies.
