Searching for pygame results in ValueError

[sztomi]

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Ubuntu 19.04
• Poetry version: 0.12.17
• Link of a Gist with the contents of your pyproject.toml file: n/a (the error is not related to pyproject.toml contents and happens even without one)

Issue

Steps

1. Run poetry search pygame

The following exception raised:

[ParseVersionError]  
Unable to parse ".9".

After some debugging, I found that the culprit is the pygame-music-grid package (which is one of the search results). Its version is .9 which semver can't parse.

[sztomi]

pip simply ignore the invalid version, so I think it's reasonable for poetry to do the same in these cases.
