I am getting this error on line 29 in vendor/lajax/yii2-asset-minifier/src/minifiers/PhpJsMinifier.php :
public function minify($path)
{
return Minifier::minify(file_get_contents($path), $this->options
}
I am using the minimal configuration
'assetMinifier' => [
'class' =>'lajax\assetminifier\Component',
],
