Script php artisan optimize handling the post install cmd event returned with error code 255

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

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:wamp64binphpphp7.1.9php.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.

I am getting an error when I run composer update: n

Generating autoload filesn> Illuminate\Foundation\ComposerScripts::postUpdaten> php artisan optimizenn n [Symfony\Component\Debug\Exception\FatalErrorException] n Call to undefined function apache_request_headers() n nnScript php artisan optimize handling the post-update-cmd event returned with error code 255n n

Problem is in my custom error handler, loaded through a service provider: n

private function include_request_headers()n<n // Include request headers in log entryn if( $request_headers = \apache_request_headers() )n <n $this->log_entry .= ‘Request headers:’ . PHP_EOL;nn foreach( $request_headers as $k => $v )n <n $this->log_entry .= «\t» . $k . ‘ = ‘ . $v . PHP_EOL;n >n >n>n n

Service Provider: n

I realize that this may not be proper usage of a service provider, since I’m not actually binding something to the container. n

The apache_request_headers function definitely exists on my server. I had to add the backslash in front of it, because without it the error above thinks apache_request_headers is part of the App\Exceptions namespace. n

I did move the loading of this service provider to the top of the stack in config/app.php, because I want to have it load as soon as possible. If I comment out the section that is throwing the error, composer update works fine, and even with uncommenting the error handler works fine too. n

Assuming that you’re actually running an Apache server — since I would imagine you’d see this error if trying to execute it on an nginx server — what happens when you comment out that bit of your error handler? Is another error thrown? Could it also be having a problem since a command line request isn’t routed through Apache? n»,»bodyInMarkdown»:»Assuming that you’re actually running an Apache server — since I would imagine you’d see this error if trying to execute it on an nginx server — what happens when you comment out that bit of your error handler?

The same error also occurred on my project right after I made a new entry to the app.php->providers, n

Turns out I was missing a comma (,) at the end of the entry even though it was the last in the list. n
