conda installer

[mr249]

Hello.
I am using Ubuntu and I have tried python versions 3.5, 3.7, 3.9, and 2.7 and each time I get an error that my python version is wrong. I have tried to create a clean environment using: conda create -c bioconda -n flye flye=2.9 and activated it and it gave the same error. I have pasted my error messages below.

• flye -> python[version='2.7.*|>=2.7,<2.8.0a0|>=3.7,<3.8.0a0|>=3.8,<3.9.0a0|>=3.6,<3.7.0a0|>=3.9,<3.10.0a0']

Your python: python=3.5

• flye -> python[version='>=3.10,<3.11.0a0|>=3.5,<3.6.0a0']

Your python: python=3.9

I was wondering if you have any suggestions. Thank you.

Hello,
I had the same issue, and I resorted to downloading the right package from https://anaconda.org/bioconda/flye/files and using conda install path_to_file.tar.bz2
Note that the "i" button on the package list indicates the required python version.

But we shouldn't have to do that in the first place. It seems that conda does not detect the right version to install.

[mikolmogorov]

I would also make sure that you are running the latest version of conda (conda update -n base conda).

Also, try being explicit with the python version: conda create -n flye_29 flye=2.9 python=3.9

If it still fails, please send the full terminal output, not just last error message.

I have same problem, and attach the terminal output.

If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.

@tujiaki please check my suggestions from the post above and post the full terminal output of each command in case they fail.

@HuoJnx what's the output of conda create -n flye_29 flye=2.9 ?

[HuoJnx]

@fenderglass
Thank you very much for your help! It works!!!

Hi, @fenderglass, I have the exact same issue as HuoJnx but your suggestion to solve the problem is not showing:

conda create -n flye -c bioconda flye=2.9 python=3.9

No success did a dependency change or is something else happening?

[mikolmogorov]

@jjkoehorst @louellette try conda create -n flye_29 -c bioconda flye=2.9

[druvus]

@jjkoehorst @louellette you need to set up channels according to this documentation. Alternatively, you could manually define the channels at the prompt as you did. Just make sure to also include conda-forge, i.e. conda create -n flye_29 -c conda-forge -c bioconda flye=2.9 as bioconda depends on conda-forge.

I would also recommend to take a look at mamba to handle conda installation as it it as a better dependency solver.
