4.1.0-RC1 - impossible to access the installation tool

[lionel-m]

After installing Contao, I can not access the installation tool.

Path: http://localhost:8888/contao410rc/web/install.php

Message:

The installation has not been completed. Open the Contao install tool to continue.
500 Internal Server Error - InternalServerErrorHttpException

Did you install Contao using Composer? I assume it did create the parameters.yml? The problem most likely is that Composer will create parameters.yml but not localconfig.php.

Did you install Contao using Composer?

Yes php composer.phar create-project contao/standard-edition=4.1.0-RC1 contao410rc

parameters.yml is ok

You're right, the folder system/config is empty

Fixed in contao/installation-bundle@4a519c0. To test the fix, you have to add the following line to the "require" section of your composer.json file:

    "require": {
        …
        "contao/installation-bundle": "dev-release/1.0.0",
    },

@leofeyer I added this line and after the composer update it returns:

[leofeyer]

Yes, sorry, it should have been:

    "require": {
        …
        "contao/core-bundle": "dev-release/4.1.0 as 4.1.x-dev",
    },

Thanks 👍

Hmm, even with the "contao/core-bundle": "dev-release/4.1.0 as 4.1.x-dev" line in the composer.json require section and an dependency update by running composer update I still get an Error 500 when running the install tool (/install.php).

The error_log shows the following stack trace:

I have just tried it with a fresh install and it worked like a charm.

composer create-project contao/standard-edition <target> dev-release/4.1.0

I have completed the Composer setup and then opened the install tool. It asked me to accept the license and to set a password and then completed the installation as usual.

Okay, thanks a lot. Setting up a new fresh install with

composer create-project contao/standard-edition . dev-release/4.1.0

did the trick. The installation went through without any problems now.

Yesterday, I did it as follows:

1. composer create-project contao/standard-edition . 4.1.0-RC1
2. Added the new requirement "contao/core-bundle": "dev-release/4.1.0 as 4.1.x-dev" to the composer.json
3. Executed the composer update command

Apparently, that was not the same. 😕
