Hopefully someone here knows a thing or 2 about this.
Short Question
I am running into an error using phpdoc on the command line, installed via pear on PHP 7.0.2. The error is:
#> phpdoc
PHP Fatal error: Uncaught Doctrine\Common\Annotations\AnnotationException:
You have to enable opcache.load_comments=1 or zend_optimizerplus.load_comments=1.
in /usr/local/php5-7.0.2-20160108-102134/lib/php/phpDocumentor/vendor/doctrine/annotations/lib/Doctrine/Common/Annotations/AnnotationException.php:193
How do I fix this error?
Details
Opcache is enabled and opcache.load_comments=1 is in my opcache.ini file, verified by using the commands: php -i | grep "Opcode" and php -i | grep "opcache" respectively. Within that .ini file I can verify that changes are loaded by checking enable and disable opcache via that file.
With that said, if I have opcache.load_comments=1 in my .ini file, why am I still getting this error?
Thanks!
I encountered the same problem while using the PHAR version of PHPDocumentor. The PHAR includes an obsolete version of Doctrine Annotations.
The older version of Annotations is referring to the opcache.load_comments setting in php.ini, which does not exist in PHP 7:
This has been fixed upstream in Annotations:
For now, using the composer version of PHPDocumentor by executing composer require --dev phpdocumentor/phpdocumentor resolved the problem for me.
You can also use composer without manually switching vendors directory contents. Just use:
composer require doctrine/annotations
to have the latest version of doctrine/annotations (at least 1.2.5 solves the problem)
phpDocumentor 2.8.5 is the default version with Ubuntu 16.04. However, php7 support wasn't added until 2.9. I got it working by using the following on the command line:
sudo apt-get install php7.0-mbstring
wget https://github.com/phpDocumentor/phpDocumentor2/releases/download/v2.9.0/phpDocumentor.phar
chmod +x phpDocumentor.phar
sudo mv phpDocumentor.phar /usr/local/bin/phpDocumentor-2.9.phar
sudo ln -s /usr/local/bin/phpDocumentor-2.9.phar /usr/local/bin/phpdoc
If you installed phpDocumentor from pear, use the following to remove it:
sudo pear uninstall phpdoc/phpDocumentor
Thanks deepdivedylan for links. However, composer require --dev phpdocumentor/phpdocumentor did not solve my problem. But reading through the links and downloading doctrine annotations patch 1.2.5 worked fine. Just download archive and replace vendor/doctrine/annotations folder with its contents.
You can download the latest version of phar from github releases .
The link from website is to an older version of it.
