Permission error when installing without root

[Aceticia]

I'm trying out poetry for managing machine learning environments on HPC. I do not have root access on it, and the permission issue is likely directly caused by that.

What I did:

1. Create a conda environment p39 with python 3.9 and pip installed in it
2. Activate p39 and ensure python and pip are under its prefix
3. Write the requirements in pyproject.toml
4. run poetry install

Then I get this error:

Command ['/gpfs/data/oermannlab/users/xl3942/.conda/envs/p39/bin/python', '/gpfs/data/oermannlab/users/xl3942/.local/share/pypoetry/venv/lib/python3.8/site-packages/virtualenv/seed/w

Content of my pyproject.toml:

[tool.poetry]
name = "poetry_trial"
version = "0.1.0"
description = ""
authors = ["Aceticia <liuchris34@gmail.com>"]
license = "MIT"

[tool.poetry.dependencies]
python = "^3.9"
torch = { url = "https://download.pytorch.org/whl/cu113/torch-1.11.0%2Bcu113-cp39-cp39-linux_x86_64.whl", platform = "linux" }
torchvision = { url = "https://download.pytorch.org/whl/cu113/torchvision-0.12.0%2Bcu113-cp39-cp39-linux_x86_64.whl", platform = "linux" }

[tool.poetry.dev-dependencies]

[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"

Note that only installing torch doesn't have this issue. The specific package that fails looks like charset-normalizer: Updating charset-normalizer (2.0.4 /tmp/build/80754af9/charset-normalizer_1630003229654/work -> 2.0.12): Failed.

I don't quite understand why this is the case: shouldn't everything be managed by a virtualenv? Am I missing something here? Any pointers will be helpful, thank you.
