PHP Fatal error: .../vendor/autoload.php: No such file
Getting a Fatal error with Version 2.17:
PHP Fatal error: require(): Failed opening required '.../selfoss/vendor/autoload.php' (include_path='.:') in .../selfoss/common.php on line 7
The require statement in common.php is unconditional:
require __DIR__ . '/vendor/autoload.php';
However, nowhere in the codebase do I find a file named autoload.php or a directory named vendor. Also, I cannot find a reference to either in installation instructions.
What am I missing?
