I am trying to get started with downloading this project:
And I've downloaded the packages in the requirements file but I can't figure out why the artic package won't download. I am getting this error:

How do I solve this problem?
I had this error while trying to install dotenv. With this command:
pip install dotenv
For anyone facing this error with dotenv. The right command actually is:
pip install python-dotenv
I faced a similar issue, due a recent change in pip. I solved it by adding the following to the installation command:
--use-deprecated=backtrack-on-build-failures
E.g. instead of pip install numpy I now ran:
pip install numpy --use-deprecated=backtrack-on-build-failures
I had the same problem with metadata-generation-failed. This GitHub issue comment helped me (Ubuntu 18.04):
sudo apt-get install python-dev
sudo apt-get install build-essential
python -m pip install -U pip or python3 -m pip install -U pip
pip3 install --upgrade setuptools
pip install numpy --use-deprecated=legacy-resolver can actually help, but there will be a red warning: pip's legacy dependency resolver does not consider dependency conflicts when selecting packages. anyway it solve my problem!
Downgrading setuptools worked for me
pip install "setuptools<58.0.0"
I was facing the same issue with another package. I have followed document . In this document, the 4 reasons behind failure.
My problem solved with 1st step only.
As mentioned there, I have upgraded pip using command: python -m pip install --upgrade pip
