Fatal error Installing using composer

[crysaro]

I got a fatal error in the browser after installing CodeIgniter using composer with the following command:
composer create-project codeigniter4/devstarter my_project_name -s dev
The error was:
Fatal error: require(): Failed opening required 'I:\\my_project_name\\app\\Config/../../vendor/codeigniter4/framework/system/bootstrap.php'
I checked the vendor folder and the "framework" folder /vendor/codeigniter4/ is missing. I only saw /vendor/codeigniter4/codeigniter4/.

I renamed the /vendor/codeigniter4/codeigniter4 to /vendor/codeigniter4/framework and there were no more errors.

I think that is related with #1871 . Try running 'composer update' and check if fix it

[crysaro]

Running 'composer update' did not fix it.
I created another test project.
composer create-project codeigniter4/devstarter testproj -s dev
After installing cd testproj
and run 'composer update' and there is still the error.

This is because of codeigniter4/devstarter#1, and it makes the devstarter unusable.

The quick fix is to open app/Config/Paths.php and change this line:

public $systemDirectory = __DIR__ . '/../../vendor/codeigniter4/framework/system';

to this:

public $systemDirectory = __DIR__ . '/../../vendor/codeigniter4/codeigniter4/system';

("framework" to "codeigniter4")

@jim-parry and I wrote about it a bit, but there's going to need to be a change to the release scripts in admin/ in order to fix this.

[jim-parry]

devstarter is not created by the release scripts. I have updated its app/Config/Paths.php, which should fix the problem for new installs this way. Existing ones might need to manually update the path, as described aboce.

[jim-parry]

Not hearing anything contrary in 6 days, I presume the fix works.

I use linux, so this worked for me:
composer update --ignore-platform-reqs
