PackagesNotFoundError / UnsatisfiableError #3

Closed rhodrid closed 5 years ago

rhodrid commented 5 years ago

Thanks for the amazing graphics you make. They're terrifyingly beautiful. I'm trying to generate an SVG of Arctic Sea Ice Volume to print on a large banner. However, I'm not getting very far and am having no luck installing the dependencies.

OS: Ubuntu 18.04 Anaconda: 3 2019.03 Linux x86_64

conda create --name ice python=3.6
conda activate ice
conda config --add channels conda-forge
conda config --set channel_priority strict
conda install --file requirements.txt

conda install gives the following error

PackagesNotFoundError: The following packages are not available from current channels:

  - basemap==1.1.0=py36_2
  - geos==3.5.1=1

If I install basemap-1.1.0-py36_2.tar.bz2 & geos-3.5.1-1.tar.bz2 from the repo I get a UnsatisfiableError and if I remove them from requirements.txt I get the same.

Tried using pip instead?

rhodrid commented 5 years ago

@MarvinKweyu I did try it before I tried it with Anaconda. 

pip3 install -r requirements.txt
Invalid requirement: '_license=1.1=py36_1'
= is not a valid operator. Did you mean == ?

I've also tried conda create --name ice3 --file requirements.txt as per the first line of requirements.txt.

conda create --name ice3 --file requirements.txt

Hello! I am very sorry for the environment errors. I have now updated requirements.txt to Python 3.7. There may be issues on your distribution with Basemap, and I recommend following the tips from https://github.com/matplotlib/basemap/issues/419.
