Installing local file dependencies fail in spite of file existing

[navyamehta]

• 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 18.04.5 LTS
• Poetry version: 1.1.4

Issue

I download the TensorRT-7.2.2.3.Ubuntu-18.04.x86_64-gnu.cuda-11.1.cudnn8.0.tar.gz file from NVIDIA and put it in the same folder as pyproject.toml. My virtualenv is 20.4.1 and install-metadata is 3.4.0. However, I get the following error on poetry install --no-dev
`
TypeError

expected string or bytes-like object

at /opt/conda/lib/python3.8/site-packages/poetry/core/utils/helpers.py:24 in canonicalize_name
20│ canonicalize_regex = re.compile("[-]+")
21│
22│
23│ def canonicalize_name(name): # type: (str) -> str
→ 24│ return canonicalize_regex.sub("-", name).lower()
25│
26│
27│ def module_name(name): # type: (str) -> str
28│ return canonicalize_name(name).replace(".", "").replace("-", "_")
`
Any help would be appreciated!

We're also facing this issue on some machines
pyhton 3.8.6 (pyenv) / wsl1 / ubuntu / poetry 1.1.3 (as 1.1.4 has an issue when resolving with private repos)

There was a case with similar symptoms here: #3628
Maybe the root cause is also similar in your case... might also be a false lead.

Closing as a duplicate of #3628 as it has more information.
