DomCrawler is available for me on 8.2.4...

 (8.2.4)  alex: ~/dev/sites/drupal8alt.dev > d php
Psy Shell v0.7.2 (PHP 7.0.7 — cli) by Justin Hileman
>>> class_exists('\Symfony\Component\DomCrawler\Crawler');
=> true
>>>

@grumpy74 how did you do the upgrade and does vendor/symfony/dom-crawler/Crawler.php exist... I guess not. I think what might have occurred here is due to https://www.drupal.org/blog/drupal-8-will-no-longer-include-dev-dependen.... This was announced in the 8.2.3 release notes - https://www.drupal.org/project/drupal/releases/8.2.3.

Hi @alexpott,

I just downloaded the drupal 8.2.4 verison and replace the files.

But the folder Symfony component is not there. How did ypu get symfony\compoent folder in yur drupal vendor folder ?

In my vendor folder, missing the folder vendor\symfony\dom-crawler that is a dev version, so your anwer was correct.

But How can I have Symfony\Component\DomCrawler\Crawler in my vendor ?

Thx for help

@grumpy74 what code do you have that is using the dom-crawler? The reason this is no longer included in 8.2.4 is that is it is only needed for running our test suite - so it is a dev dependency. If you download the 8.2.x development tarball it'll be there but it'd be best to work out why you need this. Removing the development only code was a decision based on several factors and by design so this is not a bug and not critical.

Ok thanks for the reply and explanation.

So I will include symfony domCrawler not in dev version using composer in my project.

Thaks again @alexpott, and sorry for the bad categorization in "critical" (was my first issue post).
