Composer - failed opening required for phpseclib

Question

I am trying to run a PHP file in a Vagrant VM which also uses composer for the build.

I am getting the following errors:

PHP Warning:  require(/var/www/CLIENT/vendor/composer/../phpseclib/phpseclib/phpseclib/bootstrap.php): failed to open stream: No such file or directory in /var/www/ispe/vendor/composer/autoload_real.php on line 66

Warning: require(/var/www/CLIENT/vendor/composer/../phpseclib/phpseclib/phpseclib/bootstrap.php): failed to open stream: No such file or directory in /var/www/CLIENT/vendor/composer/autoload_real.php on line 66
PHP Fatal error:  require(): Failed opening required '/var/www/CLIENT/vendor/composer/../phpseclib/phpseclib/phpseclib/bootstrap.php' (include_path='.:/usr/share/php') in /var/www/CLIENT/vendor/composer/autoload_real.php on line 66

Fatal error: require(): Failed opening required '/var/www/CLIENT/vendor/composer/../phpseclib/phpseclib/phpseclib/bootstrap.php' (include_path='.:/usr/share/php') in /var/www/CLIENT/vendor/composer/autoload_real.php on line 66

Now as far as I can tell, phpseclib shouldn't be required for this particular functionality, or anything else (though I haven't 100% confirmed the anything else bit yet).

Even so, I decided to add it to my composer.json ("phpseclib/phpseclib": "2.0.4") to get rid of the errors, with no luck.

I'm fairly new to Composer, so I am wondering precisely what I might be doing wrong here or what needs to be setup.

I can confirm that the directory /var/www/CLIENT/vendor/composer/../phpseclib/phpseclib/phpseclib/ exists, however there is no file bootstrap.php inside the directory.

Instead I see the following:

Crypt  File  Math  Net  System

EDIT: I also want to clarify that the file autoload.php is inside the vendor directory and that the PHP version of the VM is 7.0.

Composer does not only download your dependencies, it also recursively downloads dependencies of dependencies. If you are not using this library directly, it is likely a dependency of one that you are using, or one that one of those is using. You can try grepping for phpseclib in */composer.json within your vendor directory to get a better idea what is including it. – Capwell

Answer 1

I strongly believe that the cache is the problem, It cannot be 100% sure but try destroying your Vagrant instance, or

You could follow the following steps:

1. Delete the vendor folder
2. Delete composer.lock
3. Run the command composer clearcache (or clear-cache)
4. Run composer install

Oneliner for easy copy/pasting:

rm -rf vendor composer.lock && composer clearcache && composer install

Please add some explanation to your answer such that others can learn from it. Especially as removing the lock file can have severe consequences – Characharabanc

This should probably be a comment under the accepted answer as it does what the answer suggests in a single line – Gesundheit

I'm getting the same error but I don't have any composer.lock or composer.json files so I can't do the reinstall. I have no idea how this is even working without those files. – Autogiro
