Examining conflicts takes forever installing cnvkit with conda

[HeejunJang]

Hello

I tried to install cnvkit using conda.

However, it is currently unfinished on the 3rd day.

Only the process of "Examing conflicts ~~" is being repeated over and over again.

Can I solve this problem by changing my other options?

Please Help

Thank you.

Hi @HeejunJang,

In my experience this is due to conda struggling to find compatible packages within a single channel

1. What is your conda version (output of conda --version)
2. What is exact conda command you used ?
3. Do you have any channels specified in your .condarc config file ? (output of conda config --show channels)
4. What is your "channel priority" ? (output of conda config --show channel_priority)

To install CNVkit (or any "bioinformatics" package/app), I usually type conda create -n <package> -c conda-forge -c bioconda <package> => Order matters, so this tells conda to first look for dependencies in conda-forge, then in bioconda (then in defaults channel, see conda's help) => So here, please try : conda create -n cnvkit -c conda-forge -c bioconda cnvkit (possibly helpful : https://conda-forge.org/docs/user/tipsandtricks.html#how-to-fix-it)

Hope this helps ! Have a nice day, Felix.

Hello, Here's my information.

1. conda 22.9.0
2. conda update --all conda install cnvkit

• conda-forge
• bioconda
• defaults

4. channel_priority: flexible

I'll try with your suggestion and reply again.

Thank you.

Hello,

I installed with "conda create -n cnvkit -c conda-forge -c bioconda cnvkit"

and did "conda activate cnvkit"

But, Simmilar error occured before I ran cnvkit.py (source version) without conda environment.

I confirmed that similar errors occur both when running with conda and without conda.

Thank you.
