Composer show where package is composer/composer

[llaville]

I used the PHAR version of Composer 2.2 (sel-updated from 2.1 today), on my Ubuntu 18.04 LTS, Windows WSL2 environment

lrwxrwxrwx 1 root     root          25 Dec 18 07:57 /usr/local/bin/composer -> /usr/local/bin/composer-2
-rwxr-xr-x 1 devilbox devilbox 2358836 Jan 29 07:24 /usr/local/bin/composer-2

When I run this command:

composer show composer/semver -vvv

I get the following output:

requires

requires (dev)

This is expected output (package type = library)

But when I try with composer/composer itself that is also a package type = library, I got following output

And I expected this to happen: The same kind of results that we got wit composer/semver

[llaville]

I realized that the command composer show works only with packages installed, and not those available.

Sorry to disturb, its not an issue !

It does work if you use -a / --all. Probably the not found exception message could suggest that / be more informative. Reopening to keep this in mind.
