Error for creating conda env

[jiaboli007]

I got the following error:

conda env create -f requirements.yml
Collecting package metadata (repodata.json): done
Solving environment: failed

I tried on two different MacBook Pro, and got the same errors.

It will be great to provide some hints how to solve this problem.

Thanks!

[aashrafh]

Sorry, but I couldn't re-generate the error! Everything works just fine.

[jiaboli007]

Maybe it is a platform dependent issue. Which platform are you developing Mozart? Linux? I am testing on macOS Catalina 10.15.7

[aashrafh]

I'm using Linux 5.10.15-1-MANJARO and tested it on other Linux platforms and Windows works fine but didn't test it on macOS.

[jiaboli007]

Thank you so much for your information. I will try on a Linux machine. I believe Mozart is a great open source project, I really appreciate your team have put things together and a lot of people will benefit from this work. It will be nice to get Mozart working on macOS, as a lot of high-end developers for music are using Mac.

Same issue for me on Windows 64-bit:

`(base) C:\Users\Ken\Downloads\Mozart>conda env create -f requirements.yml

I am having the same issue as @ken830 , on Windows 10:
`(mozart) C:\Users\35171\Desktop\Codebase\Mozart\Mozart-main>conda env create -f requirements.yml
