Error on Composer.phar update on deployment server

Hi there, i've come across this a good few times, check that:

• There are no service providers listed in your config/app.php that you don't have the packages installed for.
• That the storage directory, and the appropriate subdirectories are writeable.
• Check the php error log if you can, you can type php -i | grep error to display info on where PHP errors might be being logged if you don't know.

Also, sometimes i find that just deleting the vendor folder and the composer.lock file (depending on your deployment setup), then running composer install from scratch fixes most errors.

I also got this error in my artisan file in my error log

PHP Parse error: syntax error, unexpected 'class' (T_CLASS), expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$'

I already did what you advice but still get the error Script php artisan clear-compiled handling the post-install-cmd event returned with an error

[RuntimeException]
Error Output:

Regarding this :

PHP Parse error: syntax error, unexpected 'class' (T_CLASS), expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$'

Which version of php are you using on that server? Keep in mind that laravel 5.1 requires

"php": ">=5.5.9",

Hoe that helps.

Best.

s.

My php version in my local is 5.5.27 which is the composer works fine. In my deployment server php version is 5.5.28
