Cannot instantiate interface PhpParser\Parser about super_closure HOT 10 CLOSED

Thanks. I'll take a look at it when I have time. That may be a couple months from now though, so feel free to send a PR if you have time.

Okay

We can just do the same as what class preloader has done?

Wait, our code already does this. How come this is nor working for you. That code never gets called on 2.x?

from super_closure.

Our code looks like this:

    /**
     * @param \ReflectionFunction $reflection
     *
     * @throws ClosureAnalysisException
     *
     * @return \PhpParser\Node[]
     */
    private function getFileAst(\ReflectionFunction $reflection)
    {
        $fileName = $reflection->getFileName();
        if (!file_exists($fileName)) {
            throw new ClosureAnalysisException(
                "The file containing the closure, \"{$fileName}\" did not exist."
            );
        }


        return $this->getParser()->parse(file_get_contents($fileName));
    }

    /**
     * @return CodeParser
     */
    private function getParser()
    {
        if (class_exists('PhpParser\ParserFactory')) {
            return (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
        }

        return new CodeParser(new EmulativeLexer);
    }

The bottom line is only ever called on php parser 1.x.

Are you noticing this issue due to a static analzyer, or due to it actually happening?

from super_closure.

I was experiencing the issue with nikic/php-parser v2.1.0 and jeremeamia/SuperClosure 2.2.0 on my production server but not on my development server (which is weird). For a quick fix in my production server, I had to use v1.4.1 of php parser. Out of curiosity, I tested SuperClosure 2.2.0 and php-parser v2.1.0 on another project on thesame production server and wasn't getting the exception. When I open your code in PhpStorm, I notice that the bottom line is underlined with
the error "Cannot Instantiate Interface Parser" thesame exception that was displayed when I was using nikic/php-parser v2.1.0 and jeremeamia/SuperClosure 2.2.0 on the prod server.

DId you restart/reload php-fpm after deploying?

from super_closure.

It looks like you just have stale caches on the productyion server.

Let me reload and see what I get.
