Multiple version peotry.lock causing TypeError: unhashable type: 'Container'

[ahmet2mir]

Short description

Hello,

When I try to convert a poetry.lock I got TypeError: unhashable type: 'Container' when peotry.lock has multiple versions

Adding a simple print(subname, subcontent, ) print before the exception show

aioredis [{'version': '>=0.3.3', 'optional': True, 'markers': 'python_version < "3.7" or python_version < "3.7" and extra == "redis"'}, {'version': '>=1.0.0', 'optional': True, 'markers': 'python_version >= "3.7" or python_version >= "3.7" and extra == "redis"'}]

Python can't convert a subcontent item of container type
to a set.

Maybe check the type before applying set and enforce using for exampe items() to convert it ?

Output

$ dephell deps convert --from-format poetrylock --from-path poetry.lock --to requirements.lock --envs main
ERROR TypeError: unhashable type: 'Container' 

Steps to reproduce

Add in peotry.lock

[package.dependencies]
aiomcache = {version = ">=0.5.2", optional = true, markers = "extra == \"memcached\""}
aioredis = [
    {version = ">=0.3.3", optional = true, markers = "python_version < \"3.7\" or python_version < \"3.7\" and extra == \"redis\""},
    {version = ">=1.0.0", optional = true, markers = "python_version >= \"3.7\" or python_version >= \"3.7\" and extra == \"redis\""},
]
