Try to install my own extension via composer in TYPO3 - composer-php

Question

My first steps with TYPO3 CMSand composer... but I cannot install my own distribution package. Try to:
composer require stsa/hellotypo3
I've got this error:
[InvalidArgumentException]
Could not find a version of package stsa/hellotypo3 matching your minimum-stability (stable). Require it with an explicit version constraint allowing its desired stability.
I've install TYPO3 9.5.1 via composer and (for testing) install a 3rd party extension like mask with composer require mask/mask. It works perfectly.
Here's my composer.json of my distribution extension, which I've uploaded to packgist. The json-file is valid, but there must be sth. wrong ..
{
"name": "stsa/hellotypo3",
"type": "typo3-cms-extension",
"description": "FLUID Templates & TypoScript",
"homepage": "https://www.hello.de/",
"keywords": [
"TYPO3",
"CMS",
"extension"
],
"authors": [
{
"name": "Stsa",
"email": "contact#hello.de",
"role": "Developer",
"homepage": "https://www.hello.de/"
}
],
"license": [
"GPL-2.0-or-later"
],
"require": {
"typo3/cms-core": "^9.5"
},
"autoload": {
"psr-4": {
"Stsa\\Hellotypo3\\": "Classes/"
}
},
"replace": {
"hellotypo3": "self.version",
"typo3-ter/hellotypo3": "self.version"
}
}
No way .. it doesn't work with that. I also try to set "minimum-stability": "stable". But honestly, I have no idea what I can do ..?! Can someone help me? Thanks.
EDIT 1: Today I've update my own extension at packgist. It must be available now with this vendor/name.
EDIT 2: Now I've made a test extension via sitepackagebuilder, upload to git, sumbit to packgist. Try to install via composer require hellotypo3de/hellotest .. still the same Error warning: Could not find a version of package hellotypo3de/hellotest matching your minimum-stability (stable). Require it with an explicit version constraint allowing its desired stability. ..?! Where's my mistake?

Answer 1

I assume you want to use your extension only on one installation as local extension. So that's the way to go:
Create a directory, e.g. packages in your project's root directory.
Move your extension into this directory and name the folder stsa-hellotypo3. The part before the dash is your namespace, the part behind the package name.
Add to your composer.json of your extension the following entry:
"extra": {
"typo3/cms": {
"extension-key": "stsa_hellotypo3"
}
}
Now TYPO3 will use stsa_hellotypo3 as extension key.
Change into your composer.json file in your TYPO3 project root the repositories entry:
"repositories": [
{
"type": "path",
"url": "packages/*"
},
{
"type": "composer",
"url": "https://composer.typo3.org/"
}
],
composer will look now into the packages folder for packages to install.
Now you can add your extension to the project:
composer require stsa/hellotypo3:#dev
The extension is symlink'ed as stsa_hellotypo3 in typo3conf/ext/ directory. With the #dev the development version is installed (which you have). you can also add a version entry into your extension's composer.json file, then you can omit the #dev.
If you do it that way you don't have to add your extension's autoloading information to the root composer.json file.

It's possible to install your local distribution extension manually. You have to insert your extension at the "require-section" and add a new type of package at the "repositories-section" in your repsoitory root composer.json. See my example:
{
"repositories": [
{
"type": "composer",
"url": "https://composer.typo3.org/"
},
{
"type":"package",
"package": {
"name": "stsa/hellotypo3",
"version":"master",
"source": {
"url": "https://github.com/name/hellotypo3-distribution.git",
"type": "git",
"reference":"dev-master"
}
}
}
],
"name": "typo3/cms-base-distribution",
"description" : "TYPO3 CMS Base Distribution",
"license": "GPL-2.0-or-later",
"config": {
"platform": {
"php": "7.2"
}
},
"require": {
"helhum/typo3-console": "^5.5.5",
"typo3/minimal": "^9.5",
"typo3/cms-about": "^9.5",
"typo3/cms-adminpanel": "^9.5",
"typo3/cms-belog": "^9.5",
"typo3/cms-beuser": "^9.5",
"typo3/cms-felogin": "^9.5",
"typo3/cms-fluid-styled-content": "^9.5",
"typo3/cms-form": "^9.5",
"typo3/cms-impexp": "^9.5",
"typo3/cms-info": "^9.5",
"typo3/cms-redirects": "^9.5",
"typo3/cms-reports": "^9.5",
"typo3/cms-rte-ckeditor": "^9.5",
"typo3/cms-setup": "^9.5",
"typo3/cms-seo": "^9.5",
"typo3/cms-sys-note": "^9.5",
"typo3/cms-t3editor": "^9.5",
"typo3/cms-tstemplate": "^9.5",
"typo3/cms-viewpage": "^9.5",
"stsa/hellotypo3": "dev-master"
},
"scripts":{
"typo3-cms-scripts": [
"typo3cms install:fixfolderstructure",
"typo3cms install:generatepackagestates"
],
"post-autoload-dump": [
"#typo3-cms-scripts"
]
},
"extra": {
"typo3/cms": {
"cms-package-dir": "{$vendor-dir}/typo3/cms",
"web-dir": "public"
}
}
}
dev-master is here important!
The composer.jsonfrom your extension looks like this:
{
"name": "stsa/hellotypo3",
"type": "typo3-cms-extension",
"description": "FLUID Templates & TypoScript",
"homepage": "https://www.hellotypo3.de/",
"keywords": [
"TYPO3",
"CMS",
"extension"
],
"authors": [
{
"name": "StSa",
"email": "hello#hellotypo3.de",
"role": "Developer",
"homepage": "https://www.hellotypo3.de/"
}
],
"license": [
"GPL-2.0-or-later"
],
"require": {
"typo3/cms-core": "^9.5"
},
"autoload": {
"psr-4": {
"Stsa\\Hellotypo3\\": "Classes/"
}
},
"replace": {
"hellotypo3": "self.version",
"typo3-ter/hellotypo3": "self.version"
},
"extra": {
"typo3/cms": {
"extension-key": "hellotypo3"
}
}
}
Or you can install your extension from packgist, but don't forget:
composer require stsa/hellotypo3:master-dev#dev
or
composer req stsa/hellotypo3:#dev

Answer 3

"require": {
"typo3/cms-core:^9.5"
},
Does that work? If not sry, but hope it helps
