Poetry downloading same wheels multiple times within a single invocation #2415
Description
- 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 (
-vvvoption).
- OS version and name: macOS 10.14.6
- Poetry version: 1.0.5
- Link of a Gist with the contents of your pyproject.toml file: https://gist.github.com/bb/501f33ad3f35eb8c26ce2513ca6074c8
Issue
When adding a new dependency, it is downloaded multiple times; I observed three downloads, two of those are unneccessary.
Starting with a pyproject.toml as in the Gist given above, I run
poetry add https://github.com/oroszgy/spacy-hungarian-models/releases/download/hu_core_ud_lg-0.3.1/hu_core_ud_lg-0.3.1-py3-none-any.whl
Then I see the following output (XXX added as markers for explanation below):

XXX - Updating psycopg2-binary (2.8.4 -> 2.8.5)
At the positions where the marker XXX is inserted, the same 1.3GB download is done again and again.
Similar, when adding another package later, again XXX marks the cursor position when the big download is done:
$ poetry add djangorestframework

XXX
I'd expect the file to be downloaded a most once and reused.
