Installation failed - trying to install modules on Drupal8 using composer

Question

So I'm getting the same error message for any module I try and install on my drupal8 enviroment. I've been shuffling files and folders around so I'm sure I've broken something.

Is there anywhere I can look in drupal log files for anymore help on the error or does someone know the cause of this error?

Thanks Mark

@RadosławHalicki I've added that now. Orginally the document root was in a 'web' folder but I moved it back to the root, so I wonder if that's something to do with it. — Mark

There is simple solution for your issue. Add web-root folder. To be fair this is good practice to store vendor outside of web folder.

Here is example how you should do it (you can also change web to docroot or anything else you like):

    "extra": {
    "drupal-scaffold": {
        "locations": {
            "web-root": "./web"
        }
    },
    "installer-paths": {
        "web/core": [
            "type:drupal-core"
        ],
        "web/libraries/{$name}": [
            "type:drupal-library"
        ],
        "web/modules/contrib/{$name}": [
            "type:drupal-module"
        ],
        "web/profiles/contrib/{$name}": [
            "type:drupal-profile"
        ],
        "web/themes/contrib/{$name}": [
            "type:drupal-theme"
        ],
        "drush/Commands/contrib/{$name}": [
            "type:drupal-drush"
        ],
        "web/modules/custom/{$name}": [
            "type:drupal-custom-module"
        ],
        "web/themes/custom/{$name}": [
            "type:drupal-custom-theme"
        ]
    },

Probably you noticed that drush commands are outside of web folder. Same way you store build scripts, server hooks, patches etc.

Yes this works (when I run it locally). I moved the files from the 'web' folder to the root because on our hosted server, it only works if the files are there. I will put a seperate question up tomorrow as I'm sure I must be missing something simple there.

This answer should probably note that these settings are what is used in recommended-project which is references in the Using Composer to Install Drupal and Manage Dependencies docs

To be fair I would recommand to change server settings to use web-root folder. This is how two best Drupal hostings work - Acquia and Pantheon. If not I will try to solve it without root folder also.
