The "Problem 1"

Oldemar

I have a lot of these composer.

$ composer require flagrow/core
[InvalidArgumentException]
Could not find a matching version of package flagrow/core. Check the packag
e spelling, your version constraint and that the package is available in a
stability which matches your minimum-stability (stable).

$ composer require flagrow/ads

./composer.json has been created

Problem 1

$ composer require flarum/core
[InvalidArgumentException]

lity (stable). Require it with an explicit version constraint allowing its
desired stability.

etc.

Can you help me?

Oldemar what do you have so far and what are you trying to achieve ?

Flarum installation instructions can be found here https://flarum.org/docs/install.html

Instructions to install extensions can be found in each individual extension discussion. The commands listed must be executed inside of the directory that contains the Flarum install.

luceos

Sounds like you're in the wrong folder/path; do you see a composer.json and flarum file?

ls -la will tell you.

Oldemar

Yes, doing a test (Profile, Settings, Start a Discussions, etc), so that is no problem. I have composer.json and I rename flarum to forum. I had doing a few of the Extensions also (forum/public/admin#/extensions).

Namecheap and host is Stellar. https://www.namecheap.com/support/knowledgebase/article.aspx/9981/2182/how-to-install-flarum

But I can not test these: https://discuss.flarum.org/t/extensions - "Problem 1" or "InvalidArgumentException" on Putty.

So why?

datitisev

Oldemar Your minimum-stability in composer.json seems to be stable - try changing it to beta.

Also - the package flagrow/core doesn't exist so it makes sense that it errored.

Oldemar

Yes, I am doing beta, not stable: composer create-project flarum/flarum . --stability=beta

And I can change Extensions, but I can not change Add Extension

Allright, flagrow/core doesn't exists. But composer require extiverse/bazaar, composer require flagrow/ads, composer require flarum/core and many others exist. But all are the errors.

putty:
`$ ls -s composer.json
4 composer.json

$ ls -s public_html/forum/

$ ls -s public_html/forum/composer.json
4 public_html/forum/composer.json

$ ls -s public_html/forum/public/`

So what to do?

clarkwinkelmann

Oldemar

cd public_html/forum
composer require package/name

flarum/core is not something you need to install yourself. It's already installed. Not sure where you copied that from.

datitisev

If clarkwinkelmann doesn't work, try running composer config minimum-stability beta and run the commands to require extensions again.

Oldemar

Thank you for composer config minimum-stability beta

But this for errors again:

clarkwinkelmann

Oldemar all those commands look successful. Do the extensions appear in the Flarum admin panel ?

You can ignore the Carbon warning, it's only for Flarum developers. Do not try upgrading Carbon. Flarum is using older libraries that still require Carbon v1.

datitisev

Oldemar You do not need to run ./vendor/bin/upgrade-carbon at all. Those are warnings that are for the developers, not the end user - you can ignore those messages every time.

When it says "Nothing to install or update", the packages/extensions have already been installed.

Also - you most likely want to downgrade dragonmantank/cron-expression as you updated it to 2 BREAKING versions higher and could break stuff in Flarum.

Do NOT replace abandoned packages from abandoned package warnings unless they are extensions you have installed (e.g. flagrow/ads).

PS: I formatted your post to use codeblocks, so it is not as long as the message repeats a few times.
