Cannot install Plugin - even after correcting composer.json

[FragenAnsForum]

In Plugin Base Guide | Shopware Documentation

the „composer.jsonon“ „require“: {
„shopware/core“: „6.3.*“
},

• even after correcting from „6.3.*“ to „~6.6.0“ (and of course: composer.json) I cannot install the plugin. php bin/console plugin:install --activate Test works, but in the Backend I get „Failed Dependency“. I’ve cleared the cache. What is the reason? I run dockware:dev\latest

What if you remove the require at all? Did you also clear the cache of the shop? Did You checked the composer.json in the shop root directory?

I…did not think of removing „require“. Should work! I cleared the cache.

Unfortunately I had to rebuild the whole container - docker cp does not suffice.

You need to find out, where the plugin is requiring Shopware 6.3. If you change to 6.6.0, clear the cache, then anywhere else its requiring 6.3…
