Cantera 2.6.0 unavailable with Conda ?

[Joe Trzaska]

I am attempting to install Cantera 2.6.0 (or whichever version has since become the most recent) via Conda, as recommended on the website.  However, when I enter the following command, the installation routine locates and installs cantera-2.5.1.

>> conda create --name ct-env --channel cantera cantera ipython matplotlib jupyter

This version is out of step with some of the tutorials, making it hard to grasp elements of the functionality.

I tried to install this version and upgrade to the latest with the command below, but I received an output reading "All requested packages already installed," and the cantera version remained 2.5.1.  

>>conda update --channel cantera cantera

Can anyone direct me towards Cantera 2.6.0?

Thanks for your help!

[Ray Speth]

Hi,

Can you provide some more information about your system? Specifically, with the ct-env environment activated, can you share the full list of packages installed, as output by conda list, and the basic information about the conda environment shown by conda info?

Regards,
Ray

Hi Ray, 

I'm also having trouble upgrading to 2.6 on Windows.  Upgrading on mac worked fine, but on Windows 10, I only have the option of 2.5.1 -- trying both cantera and conda-forge channels.

Please find the requested information attached.  Like Daniel, I am also using Windows 10.  As a troubleshooting exercise, I will try to install Cantera on my laptop running Ubuntu later today.

[Bryan Weber]

Hi all,

Sorry about this! I have two requests for more debugging: 1) Only install Cantera into a brand new environment, what do you get? 2) Specify the version of Cantera to be installed, conda install -c cantera cantera=2.6.0 what do you get?

Thanks!
Bryan

Hi Daniel,

Thanks! The conda-forge one is known, conda-forge doesn't build Windows packages for Cantera, since they're available on the cantera channel.

For the conda create ... cantera=2.6.0, can you show the rest of the output from the unsatisfiable error? That will actually say what the conflict is. Could you also try the mamba solver?

conda install -n base mamba

mamba create -n cantera26 -c cantera cantera=2.6.0

Thanks!

Bryan

Hi Daniel,

I _think_ I resolved this this afternoon. We hadn't properly labeled the new libcantera package in our channel. Please give it another try (regular conda should be fine) and let me know how it goes.

Best,

Bryan

[Joe Trzaska]

Bryan - I was able to get 2.6.0 installed this morning, thank you!  FYI I did have to specify the version ( ... cantera=2.6.0), as without that inclusion conda continued to locate version 2.5.1, instead.

Hi Bryan,

Yes, worked fine for me too -- but as Joe wrote, I had to specify cantera=2.6.0.  Thanks for figuring it out!
