Howto Install Plugin_Manager On Roundcube 1.1.3

[Norbert]

Hello,
I read "Getting started" on https://plugins.roundcube.net/. I added in my local file composer.json the line
...
"require": {
"php": ">=5.3.7",
"roundcube/plugin-installer": "~0.1.6",
"pear-pear.php.net/auth_sasl": "~1.0.6",
"pear-pear.php.net/net_idna2": "~0.1.1",
"pear-pear.php.net/net_sieve": "~1.3.4",
"pear-pear.php.net/mail_mime": "~1.9.0",
"pear-pear.php.net/net_smtp": "~1.6.3",
"patchwork/utf8": "~1.2.3",
"myroundcube/plugin_manager-installer": "dev-master"
},
But after php composer.phar update, I have [ErrorException] Undefinided Index.
How can I can to solve it?

Try with "roundcube/plugin-installer": "*",

Thank you, I have no error now. But it seems there is a confusion between plugin_installer and plugin-installer. With a previous version (1.0.4), I had a plugin menu in settings but now (1.1.3) nothing.
I read plugin_installer is obsolete. I'm looking a tool to manage all plugins and its version.
