Drupal-project: Could not scan for classes inside "scripts/composer/ScriptHandler.php" which does not appear to be a file nor a folder

[kenneho]

Hi.

I've ran this command to create a new Drupal project:
composer create-project drupal-composer/drupal-project:8.x-dev /app --stability dev --no-interaction

When running composer install --no-dev, I get this error:

[RuntimeException]
Could not scan for classes inside "scripts/composer/ScriptHandler.php" which does not appear to be a file nor a folder

I don't know if this is related, but I installed my project to /app, while the composer install output seems to be trying to access files under /var/www (which I've deleted, since I don't use it):

Cannot create cache directory /var/www/.composer/cache/repo/https---packages.drupal.org-8/, or directory is not writable. Proceeding without cache
Cannot create cache directory /var/www/.composer/cache/repo/https---packagist.org/, or directory is not writable. Proceeding without cache
Cannot create cache directory /var/www/.composer/cache/files/, or directory is not writable. Proceeding without cache
Could not scan for classes inside "scripts/composer/ScriptHandler.php" which does not appear to be a file nor a folder

I suspect there's something with my local setup that's causing this. I'll investigate further...

On the server i ran composer create-project, running composer install works fine. But I've checked the /app folder into source code, and when my build server run composer install, everything works fine until composer start generating autoload files:

<snip>
- Installing drush/drush (9.3.0): Downloading (100%)
- Installing vlucas/phpdotenv (v2.4.0): Downloading (100%)
Generating autoload files
[RuntimeException]
Could not scan for classes inside "scripts/composer/ScriptHandler.php" which does not appear to be a file nor a folder 

I suspect composer is looking for ScriptHandler.php in the wrong path. The actual path is /app/composer/ScriptHandler.php, not scripts/composer/ScriptHandler.php that it currently looks for.

In composer.json, I change classmap like this, which seems to have resolved my issue (need more testing to verify):

"classmap": [ "./composer/ScriptHandler.php" ],

This could be related to the absolute path (/app), please try a relative path instead. Could be a bigger composer issue.

I've run into this same issue, just by installing a fresh copy of the project, then in a Dockerfile, running:

FROM composer as vendor

COPY composer.json composer.json
COPY composer.lock composer.lock

RUN composer install \
    --ignore-platform-reqs \
    --no-interaction \
    --no-plugins \
    --no-scripts \
    --prefer-dist

I'll try that classmap change as well and see if it helps. The composer image installs into ./app as well.

...and now I feel dumb. I forgot to copy in the scripts/ dir in my Dockerfile above. This works:

FROM composer as vendor

COPY composer.json composer.json
COPY composer.lock composer.lock
COPY scripts/ scripts/
COPY web/ web/

RUN composer install \
    --ignore-platform-reqs \
    --no-interaction \
    --no-plugins \
    --no-scripts \
    --prefer-dist

where location scripts / dir ? i am try search but not found

[smoore0509]

Here's what I did:

• in the top level of the project (where composer.json is):
  $ find ./ -name 'ScriptHandler.php'
  That returned
  .//vendor/consolidation/robo/scripts/composer/ScriptHandler.php
  OK, that's kind of weird, but I went into composer.json and reset classmap thus:
  "classmap": [
  ".//vendor/consolidation/robo/scripts/composer/ScriptHandler.php"
  ]
  And now composer works (in that project anyway :-))

/var/www/.composer/cache/ not writeable error and which I've deleted, since I don't use it definitely sounds like a Composer issue. Would be interesting what $ composer config --global --list | grep cache and whoami returns. I suggest you reinstall Composer and retry.

Please feel free to reopen this issue by adding more info/steps/commands to reproduce this issue.

OH! Thank you. This was exactly my issue. Thank you
