Question & Answer :
I cognize that this content has been posted galore occasions, however for maine it appears to beryllium a antithetic job.
So, this mistake
Informing: necessitate(vendor/autoload.php): failed to unfastened watercourse: Nary specified record oregon listing successful C:\xampp\htdocs\site_web\send_mail.php connected formation three
Deadly mistake: necessitate(): Failed beginning required ‘vendor/autoload.php’ (include_path=‘C:\xampp\php\PEAR’) successful C:\xampp\htdocs\site_web\send_mail.php connected formation three
seems astatine the begining of my codification from this formation:
necessitate 'vendor/autoload.php';
Truthful, I conjecture location essential beryllium a /vendor/autoload.php record location successful my machine (I person put in composer and ran composer necessitate phpmailer/phpmailer).
Truthful, I regarded for this record utilizing: dir /s autoload.php successful the Home windows bid formation, and recovered 1 present: C:\Home windows\SysWOW64\vendor\autoload.php,
however for maine, syswow64 folder has thing to seat with autoload.php, I don’t seat what I americium lacking present.
What you’re lacking is moving composer instal, which volition import your packages and make the vendor folder, on with the autoload book.
Brand certain your comparative way is accurate. For illustration the illustration scripts successful PHPMailer are successful examples/, beneath the task base, truthful the accurate comparative way to burden the composer autoloader from location would beryllium ../vendor/autoload.php.
The autoload.php you recovered successful C:\Home windows\SysWOW64\vendor\autoload.php is most likely a planetary composer set up β wherever you’ll normally option issues similar phpcs, phpunit, phpmd and so on.
composer replace is not the aforesaid happening, and most likely not what you privation to usage. If your codification is examined with your actual bundle variations past moving replace whitethorn origin breakages which whitethorn necessitate additional activity and investigating, truthful don’t tally replace until you person a circumstantial ground to and realize precisely what it means. To make clear additional β you ought to most likely lone always tally composer replace domestically, ne\’er connected your server arsenic it is fairly apt to interruption apps successful exhibition.
I frequently seat complaints that group tin’t usage composer due to the fact that they tin’t tally it connected their server (e.g. due to the fact that it’s shared and they person nary ammunition entree). Successful that lawsuit, you tin inactive usage composer: tally it domestically (an situation that has nary specified restrictions), and add the section vendor folder it generates on with each your another PHP scripts.
Moving composer replace besides performs a composer instal, and if you bash not presently person a vendor folder (average if you person a caller checkout of a task), past it volition make 1, and besides overwrite immoderate composer.fastener record you already person, updating bundle variations tagged successful it, and this is what is possibly unsafe.
Likewise, if you bash not presently person a composer.fastener record (e.g. if it was not dedicated to the task), past composer instal besides efficaciously performs a composer replace. It’s frankincense critical to realize the quality betwixt the 2 arsenic they are decidedly not interchangeable.
It is besides imaginable to replace a azygous bundle by naming it, for illustration:
composer replace ramsey/uuid
This volition re-resoluteness the interpretation specified successful your composer.json and instal it successful your vendor folder, and replace your composer.fastener record to lucifer. This is cold little apt to origin issues than a broad composer replace if you conscionable demand a circumstantial replace to 1 bundle.
It is average for libraries to not see a composer.fastener record of their ain; it’s ahead to apps to hole variations, not the libraries they usage. Arsenic a consequence, room builders are anticipated to keep compatibility with a wider scope of adult environments than app builders demand to. For illustration, a room mightiness beryllium suitable with Laravel 5, 6, 7, and eight, however an app utilizing it mightiness necessitate Laravel eight for another causes.
Composer 2.zero eliminated immoderate remaining inconsistencies betwixt instal and replace outcomes; if you’re moving composer 1.x you ought to decidedly improve.
