I just published my first package on Packagist: https://packagist.org/packages/felixfbecker/advanced-json-rpc.

I tagged the first commit with version v1.0.0, which Packagist detects correctly. When trying to install the package with composer

composer require felixfbecker/advanced-json-rpc

I get

[UnexpectedValueException]
Invalid version string ""

What am I doing wrong?

Try add some minimum-stability into the composer.json file

    "minimum-stability": "stable",

Or 

"minimum-stability": "dev",
"prefer-stable" : true

and then update the packag in https://packagist.org

  • Do you mean in the composer.json of the library or the composer.json of the project? Also > Remember though: Most likely the reason why you need those stability flags is because the maintainers of your dependencies did not tag stable releases. You should go and annoy them right now so they add branch-aliases and tag releases. And as soon as they do, you can nuke those stability flags and be happy again. How can I tag a stable release? – felixfbecker Aug 24 '16 at 18:28

After all, it was not a problem with the published package, but with the project's composer.json.
